Presentation Title

Development of New Light-Cured Fluoropolymers for High Performance Coatings and Aerospace Elastomers

Format of Presentation

Poster to be presented Friday March 31, 2017

Abstract

The development of high performance materials is of great interest due to the increasing demands of high technology in automotive and aerospace industries, chemical plants, and microelectronics. Materials that are composed of fluorine-containing carbon chains with flexible linkages find many applications within these fields as they exhibit properties such as excellent temperature stability, oil and water repellency, resistance to oxidation, and low flammability.

This presentation outlines the successful modification of a specific type of fluorinated building block – poly(hexafluoropropylene oxide) or p(HFPO) – to contain functionalized endgroups capable of photopolymerization (i.e. joining the building blocks together to form new materials upon exposure to UV light). Photopolymerization is desirable as it is fast, requiring no more than a few minutes as compared to hours, and can be carried out at room temperature, thus consuming minimal energy. Future work involves exploiting the complementary properties of the maleimide endgroup (an electron acceptor) and ester vinyl ether endgroup (an electron donor) on these p(HFPO) building blocks to form a photo-curable copolymer (a new material incorporating both building blocks) in the absence of a photoinitiator, which typically are toxic and are unable to be removed from the final material. Specific applications for this copolymer include paints resistant to graffiti, coatings for optical fibers, components of lithium batteries, and O-rings and gaskets used in aerospace industry. The p(HFPO) maleimide building block itself is of interest for its ability to act as a photoinitiator in other photopolymerizations, as an alternative to toxic photoinitiators.
