磺化聚醚醚酮酮/氨基封端超支化聚酰亚胺复合膜的制备
Preparation of the Blend Membranes Based on Sulfonated Polyetheretherketoneketone and Amine-terminated Hyperbranched Polyimide
摘要
Abstract
An amine-terminated hyperbranched polyimide(Am-HBPI)was introduced into a sulfonated flurenyl-containing polyetheretherketoneketone(SFPEEKK)matrix to form"acid-base"blends for proton conductive membranes. The uniform and flexible blend membranes were obtained by a solution casting proce-dure with a unique phase-separation microstructure. Both TEM and SEM images clearly showed that the nano-sized Am-HBPI particles were well dispersed in SFPEEKK continuous phase. In comparison with the pristine SFPEEKK membrane, the blend membranes containing Am-HBPI"performance-enhancing component"ex-hibited improved dimensional stability and better mechanical properties. Meanwhile, their proton conductivity could be 0.12—0.16 S/cm at 100 ℃.关键词
