  Abstract

A porous nanofi ber web with a hierarchical pore structure was formed by electrospinning and nonsolvent-induced phase separation (NIPS) processes. Phenyl silsesquiazane (PSSQZ) containing 20% high-molecular-weight poly(ethylene oxide) (PEO) was electrospun to form a nanofi ber web, where a mixture of high volatility solvent and low volatility nonsolvent induced the pores within the nanofi bers through NIPS mechanism. The content of the polymers and the type and ratio of solvent/nonsolvent signifi cantly aff ected pore formation, and a nanofi ber web with a hierarchical pore structure was formed using 90/10 of PSSQZ/PEO, 80/20 of chloroform/decane, and 5 wt% total polymer content. The nanofi ber web was then converted to inorganic nanofi bers by heat treatment at 700
