Abstract:

Polymeric microporous films were successfully prepared from polyetherimide/chloroform solutions by water assisted method. The influence of key operating conditions on the morphology of pores, such as relative humidity and polymer concentration, were studied. By optimizing the humidity and polymer concentration, the regular and uniform microporous films based on polyetherimide(Ultem 1010) could be obtained. Moreover, the thermal stability, corrosion resistence and mechanical properties of the microporous films were excellent.

Key words: Polyetherimide; High performance polymer; Microporous film; Water assisted method
