Conductive composites of polyamide-6 with polyaniline coated vegetal fiber

摘要: Abstract Vegetal fibers, like curaua are used as reinforcement for thermoplastics in biocomposites, due to their low density and availability. Polyaniline can be deposited on the surface of fibers producing electrically conductive fibers. The conductivity these PAni treated suggest use antistatic agents. Composites polyamide-6 with Pani-treated were prepared a twin-screw extruder specimens obtained by transfer-molding. electrical properties modified composites measured mechanical evaluated tensile tests. morphology composites, fibrillation process adhesion at polymer/fiber interface observed scanning electron micrography. ATR-FTIR showed that most important bands present thermogravimetric results PAni-coated two distinct weight loss processes positive shift degradation process, corresponding stabilization effect. composite has 5 × 10−7 S cm−1, three orders magnitude higher than pure polyamide-6, range materials. show better performance polymer matrix, SEM shows good interface.
