Synthesis of a hexafluoropropylidene-bis(phthalic anhydride)-based polyimide and its conducting polymer composites with polypyrrole

Preparation and Characterization of 4,4′‐Bis(4‐aminophenoxy)diphenyl Sulfone Based Fluoropoly(ether‐imide)/Organo‐Modified Clay Nanocomposites

“…[25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] The most common procedure used in this investigation is a simplified one-pot-two-step polymerization process [40] as shown in Scheme 2. The polymerization was carried out until completion of the 1 st step shown in reaction scheme, and (6FDA þ p-SED) poly(ether-amic acid) (6F-PEAA) was successfully synthesized from 2,2 0 -bis(3,4-dicarboxyphenyl)hexafluoropropane dianhydride (6FDA) and 4,4 0 -bis(4-aminophenoxy)diphenyl sulfone (p-SED), as follows.…”

“…Several procedures for the preparation of polyimides are reported in the literature 25–39. The most common procedure used in this investigation is a simplified one‐pot‐two‐step polymerization process40 as shown in Scheme .…”

Improving electrochromic properties via copolymerization

“…On the other hand, they have poor mechanical properties; they are often insoluble, nonmelting, and thus not processible. A variety of methods such as grafting alkyl groups into the main chain, the synthesis of soluble precursors, and the preparation of conducting polymer composites, blends, and copolymers are used to improve mechanical properties [8].…”
