Transparent and heat resistant polymer materials have gained much attention in the field of next-generation flexible electronic devices such as display, solar cell, e-paper and etc. New poly(arylene ether)s (PAEs) with both transparency and heat-resistance were prepared by a polycondensation of FBPODS, an ordered-sequence aromatic dihalide, and cardo typed aromatic diols that contain fluorene or adamantane moiety. The resulting polymers were found to be amorphous by X-ray diffractometry and Tg ranged from 200 to 250 ℃. Based on TGA and TMA data, they exhibited excellent thermal stabilities. They had good mechanical properties with modulus of 1750-2150 MPa. The optical transmittance for the PAE films (ca. 20μm thick) was over 70% at 450-800 nm and they also showed water uptake of about 0.65% regardless of their chemical composition. |
