Synthesis and Preliminary Properties of Novel Poly(aryl ether)s Containing β -Naphthalene Pendant Group

Abstract

Two novel poly(aryl ether)s containing β-naphthalene pendant group were synthesized and the structures of these polymers were confirmed by 1 HNMRspectroscopy.Thepolymers exhibited good thermal stabilities with high T g of 256°Cand 274°C, respectively. The polymers are soluble in common organic solvents, such as DMAc, DMSO, CH 2 Cl 2, and CHCl 3, and can be electrospun into microfiber (1-5 μm) with lots of nanopores (>100 nm) from CHCl 3 solution. These fibers showed high hydrophobicity, and the contact angle of fibers is above 120°.
