Multi-phase design and morphological control of 9: 15 pm proton exchange membrane
Wes Hezzleton E.
Professor Simmons, Department of aggregation engineering
At the school of polymer engineering at Akron University in 2007, Lloyd Robertson, Henry Wu and Jim McGrath, extended Lloyd\'s pioneering identification of the upper limit of gas separation to the performance of proton exchange membranes (PEMs).
The basic problem with PEMs in this case is to optimize penetration, proton flux and durability.
Unfortunately, normally, the highly expanded film does not have very good mechanical properties.
The two variables proton transport and durability are closely related to traditional homopolymers or random polymer films.
High conductivity requires high ions
Exchange capacity (IEC)
, This will also produce higher water solubility in the membrane, but high water expansion will reduce durability.
Through the survey literature, Lloyd and his co-authors observed that there appeared to be an upper limit between conductivity and water concentration in the proton exchange membrane.
Just like the upper limit of gas separation, they propose that to exceed the upper limit, the form of the membrane needs to be completely changed.
By introducing another phase in morphology, decoupling of transport and mechanical properties can be achieved, which can be achieved through polymer mixtures, block polymers, or polymer composites, many research groups around the world have been considering new designs for PEMs based on polyphase polymer systems.
Similar work is being done for membranes in other separation processes, such as reverse osmosis and batteries.
In this presentation, we will discuss our development research on the pems for the preparation of polymer mixtures and nano-composites.
Specifically, the polymer mixture is made up of a poly with a neutral polymer or another Poly and nano-composite material that contains a dispersion in a lower IEC
In both cases, the effect of the electric field alignment of the conductive phase in the direction of transmission will be discussed. 9:20-
9: 50 influence of Lloyd Robertson on gas separation membrane
Kenneth A Freeman
Kobe professor of chemical engineering at the University of Texas today, gas separation using polymer membranes is widely used in applications such as air separation and dehydration, hydrogen purification and separation, and natural gas purification.
Lloyd Robertson has made many fundamental contributions to science and engineering in this field, contributing to today\'s success.
For example, he was the first person to compile \"so-and-so.
In today\'s most widely recognized and used form, called the \"upper limit\" trade-off between engas permeability and selectivity, his groundbreaking paper on the subject is the most-citednon-
Review article in The Journal of Membrane Science.
The gas permeability properties of new materials are usually compared to Lloyd\'s original upper limit or his recent update to show progress in separation performance.
In 2007, he extended the concept to the field of fuel cell film.
His work inspired our efforts to develop cap models, as well as recent work that demonstrated this trade-off between membrane flux and the selection of porous liquid filtration membranes and those used for seawater desalination.
Based on this concept, Lloyd uses a huge database of gas permeability data in thousands of polymers to define the best value of effective gas molecular size for penetration performance.
As interest extends to the high temperature gas separation field, the temperature dependence of the upper limit has been described in theory and presented in a joint paper between Lloyd and our team in Texas.
This presentation will highlight these and Lloyd\'s other contributions to the field of gas separation in an attempt to provide some perspective on the enormous impact and impact Lloyd\'s work has and will continue to have in the field of Membrane Science. 9:55-

Improving the thermal efficiency of screw extrusion 1259996 at 9: 00 | Adrian Kelly, University of Bradford, has complex thermal problems associated with polymer melt extrusion.
The process efficiency associated with melting and conveying polymers using barrel internal rotating screws is highly dependent on the friction, heat and flow properties of the polymer, the chosen screw geometry, and the specified extruder operating conditions, including the machine set temperature and screw speed.
The melting of the polymer is achieved by the combination of heat conduction and viscous shear.
This process is energy intensive, but it cannot be simply expressed as optimization with the energy per kilogram of the product.
The quality of the extrusion is also crucial.
Meltquality can be defined based on the value and uniformity of the melttemperature.

Three dimensional finite element optimization technology.
In this study, various strategies were used to optimize the geometry to meet the ideal flow target of the mold outlet and the minimum pressure drop.
Finite element simulations using numerical optimized geometry predict more uniform flow than simulations using baseline geometry.
However, some numerical optimized mold geometry obtained in this study is impractical for manufacturing.
So we see the power of CFD.
The optimization-based approach leads to potentially better performance options;
But we have also seen the need to understand design techniques and manufacturing techniques in order to analyze the practicality of the proposed optimization solution.
By using geometric constraints, this knowledge can be used to redirect optimization to a more practical solution.

Impact of wall height not supported at 10: 00 on ABS 1260092 linear vibration welding | Avraham Benatar, Ohio State University vibration welding is very popular in the automotive industry due to short cycle and high joint quality.
In the rear lights of the car, it is often used to weld the silicone lens onto the ABS backing.
The design of the welding fixture adapts to the size change of the part, usually resulting in welding of long and high unsupported walls.
Therefore, we study the T-of the linear vibrationwelding vertical organic glass plate horizontal ABS plate-
Joint with the vibration motion to the horizontal to the PVC plate.
The effects of the height, vibration amplitude, meltdown, and pressure of the non-supported silicone wall on the strength of the joint were evaluated.
As expected, for short unsupported walls, high quality welds with short welding times are produced.
However, as the height of the wall increases, the welding time required to produce the weld will be longer until the height is so large that the PVC plate will bend instead of producing relative motion at the interface.

Stable stage in order to achieve reproducible welding performance
State melting formation and copper-
The rate of decline must be reached in this process.
Recent results show that the decay time has a huge impact on the morphology and mechanical properties of the weld.
These results confirm the known structure.
Parts made in industry are more or less always off target geometry.
During the connection, the scaling warping of the part, the local sink marking or the side bias can lead to a local difference.
In the case of component warpage, the current policy is to increase the connection pressure to achieve a full match between the two joints. The force-
During the welding process, due to the deformation of the joint part, the local connection pressure on the welding length is different.
These different connection pressures lead to different welding properties.
This paper shows the impact on the process behavior and on the welding quality, local and global.
Welding for a long time did not help us.

Zirconium phosphate (ZrP)
Synthesis in a solution system containing polymers (
Such as polyethylene (pet)or monomer.
During the synthesis of ZrP, the PEG chain is embedded in the mezzanine space of ZrP, resulting in a larger mezzanine distance, which is similar to the insertion compound.
The correct recipe ratio has proven to be the key to avoiding the formation of the original ZrP and avoiding interfering with the growth of the ZrP layered structure.
It was also found that longer polymer chains were desirable in order to minimize the formation of the original ZrP, but did not affect the sandwich distance.
All PEG chains are completely parallel to the layer plane.
In addition to the polymer, many other molecules have also been successfully embedded in the mezzanine space to form a plug-in structure.

9: 30 using an infrared temperature sensor 1259862 to monitor the thermal uniformity in screw extrusion | Adrian Kelly, University of Bradford studied the ability of the infrared temperature sensor to provide information related to the thermal uniformity and melting performance of a single extruder.
The infrared sensor is located in the barrel of the single screw extruder close to the end of the Screw, and also in the instrument mold adapter.
The results were compared with the results obtained by the thermocouple mesh sensor located at the entrance of the extrusion die.
In the experiment of three extruder screw geometry, two grades of high density polyethylene were used in a certain screw speed range.
When located in the mold adapter, the infrared sensor detects temperature changes related to the melting instability, but these changes are less than the actual fluctuations detected by the thermocouple mesh sensor, suggesting that the depth of penetration of the infrared sensor is limited.
When located in the extruder barrel, the infrared sensor provides a batch measurement of the melting temperature on the depth of the spiral channel in the measurement section, which is more closely related to the temperature measured using a thermocouple mesh.
