PREPARATION AND CHARACTERIZATION OF POLYIMIDF/POLYANILINE COMPOSITES
PI/PANI复合材料的制备与表征

Polyimide(PI)/polyaniline(PANI) nanocomposites were prepared as a electromagnetic wave absorption material. Nano-PANI was synthesized with DBSA as the emulsifier and doping agent and APS as oxidant by a micro-emulsion method. On this basis,PAA/PANI composites were synthesized in NMP saturated solutions of PANI at room temperature,then PI/PANI composites were prepared through imidization.The crystallization of polymers was characterized by XRD,the intermediate and polymer were also characterized by FTIR spec...
