high temperature polymers ppt pdf
Post: #1

I am a student of chemical engineering.. i need to prepare a ppt on High temperature polymers.. need some help or advised ppt for reference as soon as possible.
Or if possible, i want to work on the recent advancements in the development of processable high temperature polymers because i need to make the ppt in specific topic rather than on a generalize field.
i would also like to work on the ppt of the following topic whose abstract is as follows- PEMFC systems: the need for high temperature polymers as a consequence of PEMFC water and heat management

The proton exchange membrane fuel cell (PEMFC) is usually operated at elevated pressure, requiring the use of a compressor. Also the operating temperature is low, generally below 80 °C. For many applications, a somewhat higher operating temperature would be preferable. This paper describes the reasons for pressurised operation at, or close to, 80 °C in terms of water and heat management issues. It is concluded that a new type of proton conducting material is highly desirable, having many of the good Nafion properties, but based on a proton conduction mechanism that does not require the presence of large amounts of water in the electrolyte.

thank you.. waiting for the help.

High performance plastics are plastics that meet higher requirements than standard or engineering plastics. They are more expensive and are used in smaller quantities. High performance plastics differ from standard plastics and engineering plastics mainly because of their temperature stability, but also because of their chemical resistance and mechanical properties, quantity of production and price.

There are many synonyms for the term high performance plastics, such as: high temperature plastics, high performance polymers, high performance thermoplastics or high technology plastics. The name of high temperature plastics is in use due to its continuous service temperature (CST), which is always higher than 150 ° C by definition (although this is not its only characteristic, as can be seen above).

We often talk about polymers instead of plastics, since both terms are synonymous in the use of engineering. If the term high-performance thermoplastic is used, it is because both standard and technical plastics and high performance plastics are always thermoplastic. Thermosets and elastomers are outside this classification and form their own classes.

However, the differentiation of less powerful plastics has varied over time; while nylon and poly (ethylene terephthalate) were initially considered potent plastics, they are now ordinary.
