FUNCTIONAL POLY(arylene ether)S FILMS WITH HIGH THERMAL STABILITY AND OPTICAL TRANSPARENCY

摘要

In the study, we propose four novel variationally substituent pendant of poly(arylene ether)s with outstanding thermal stability and high optical transmittance. The poly(arylene ether)s are synthesized via nucleophilic displacement on a 2-trifluoromethyl-activated bisfluoro monomer, which reacted with bisphenyl pendants. The experimental result shows that the poly(arylene ether)s moned outstanding physical characteristics, such as glass transition point of~325℃, decomposition temperature Td~540℃ at a weight loss of 5%. In addition, high transmittance of 92% in the visible region, a low dielectric constant of ~ 1.9, and good mechanical property of the poly(arylene ether)s films were experimentally verified. Thefulms good physical property leads to a potential application of poly(arylene ether)s compounds as polymer substrates for electro-optical systems.
