Descrição

Descrição geral

A tunable, polymeric, photonic material.

Poly(4,5-difluoro-2,2-bis(trifluoromethyl)-1,3-dioxole-co-tetrafluoroethylene)(AF2400) is a fluorinated polymer that formed by copolymerization of 4,5-difluoro-2,2-(trifluoromethyl)-1,3-dioxole(PDD) and tetrafluoroethylene(TFE). It has a relatively high glass transition temperature(T_g) and optical transparency which allows it be a photo-stable polymer that can be used for a wide range of coating application in electronic and electrochemical industry.

Aplicação

AF2400 dissolved in supercritical CO₂ as a solvent can be used as an activated layer that forms an electrode for fuel cell applications. It may be used in the fabrication of organic nanofiltration membrane with polytetrafluoroethylene(PTFE) that can be used in the extraction of hexane from crude mixture of soybean oil. Nanocomposites of silver nanoparticles(AgNPs) may be formed by incorporating AF2400 via vapour phase co-deposition process that can be used in surface enhanced raman spectroscopy sensors and color filters.

Optically transparent due to the cycloether moieties in the structure which prevent crystallization. Also possesses nonadhesive characteristics and low refractive index making it more interesting than PTFE for optical applications.

Optoelectronic devices for optical clarity, low-refractive index coating for optical devices, protective coating for chemical resistance, release coating, and sight window for harsh chemical environments.

Used as a fluoropolymer for 157-nm lithography.

Características e benefícios

High gas permeability, high compressibility, good creep resistance, low thermal conductivity, transparent to microwaves and the lowest dielectric constant of any known fluoropolymer.

forma física

Amorphous copolymer.
