摘要：

A study is made of the possibility of using fullerene-containing polymers as materials for gas-separating membranes. Fullerene-containing poly(phenylene oxide) was prepared and its density and free volume were estimated. The coefficients of gas permeability and the selectivity factors for separation of air into oxygen and nitrogen were measured for poly(phenylene oxide) having various fullerene contents. A correlation is established between the change in the transport properties and the free volume. It is shown that modifying poly(phenylene oxide) with fullerene is potentially useful for improving the transport properties of the membranes. (C) 1999 American Institute of Physics.
