We have studied carbon molecular sieve membranes derived from<br />

poly(phenylene oxide) (PPO) as a new type of carbon precursor. Carbon hollow<br />

fiber membranes are promising for the industrial use of membrane modules,<br />

however, one of the main problems of carbon hollow fiber is brittleness. In this<br />

study, a flexible carbon hollow fiber membrane derived from PPO derivative is<br />

investigated and a membrane module containing hundreds of carbon hollow<br />

fibers is successfully prepared. This carbon hollow fiber membrane module<br />

showed not only better mechanical stability but excellent performance for the gas<br />

separation such as CO2/CH4.
