Development of Compatibilized Polyamide 1010/Coconut Fibers Composites by Reactive Extrusion with Modified Linseed Oil and Multi-functional Petroleum Derived Compatibilizers

This work reports the preparation and characterization of fully bio-based polymer composites with coconut fibers (CFs) as an alternative to wood-plastic (WPCs), typically based on petroleum derived materials. Polyamide 1010 (PA1010) was melt-extruded 20 wt% CFs and, after that, shaped into pieces by injection molding. Four different multi-functionalized compatibilizers were tested increase polymer-fiber interactions subsequent improvement toughness. These consisted two chemically modified vegetable oils, namely maleinized epoxidized linseed oil (MLO ELO) respectively, commercial additives from glycidyl functionality, that is, low-functionality epoxy-based styrene-acrylic oligomer (ESAO) polystyrene-glycidyl methacrylate random copolymer (PS-GMA). The addition all four improved both mechanical thermomechanical properties composites, thus resulting in high-performance composite materials relatively low water uptake. Furthermore, morphology obtained revealed extraordinary embedment biopolymer matrix, which plays a crucial role improving Among compatibilizers, those oils can be considered most interesting ones due they offer more sustainable solution.
