General description

Poly[4,5-difluoro-2,2-bis(trifluoromethyl)-1,3-dioxole-co-tetrafluoroethylene] (AF1600) is a fluorinated polymer that is formed by the copolymerization of 2,2-bis(trifluoromethyl)- 4,5-difluoro-1,3-dioxole and 1,1,2,2,- tetrafluoroethylene. It is an optically transparent photo-stable polymer with a high glass transition temperature (Tg), which can be used as a coating in electrochemical and electronic devices.
A tunable, polymeric, photonic material.

Application

AF1600 can form a hydrophobic coating on a silicon wafer that has a contact angle in the range of 115-120° which can be potentially used in agrochemical and printing applications. It may also form a self-assembled monolayer (SAM) on aluminum plates which can be used in the fabrication of water driven triboelectric nanogenerators (WTENGs).
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.

Physical form

Amorphous copolymer.
