In this work, we propose a green method for decorating natural fibers derived from dwarf palm waste with graphene oxide (GO) sheets. In detail, plasma-treatment was used to activate fiber surface for the subsequent GO-coating, which was performed in water. Poly(butylene adipate-co-terephthalate) (PBAT)-based composites incorporating 50% of either raw, plasma-modified or hybrid fibers were prepared by compression moulding and thoroughly analysed to investigate the processing-structure-properties relationships of these systems. The outcomes reveal that combining plasma treatment and GO coating enables fabricating green composites with significantly improved mechanical performance (stiffness and tensile strength increments of up to 500% and 300%, respectively) and electrical conductivity on the order of 10 S/m.

基于等离子体激活和 GO 涂层矮棕榈纤维的多功能绿色复合材料

在这项工作中，我们提出了一种用氧化石墨烯（GO）片装饰源自矮棕榈废料的天然纤维的绿色方法。具体来说，使用等离子处理来激活纤维表面，以便随后在水中进行 GO 涂层。通过压缩成型制备含有 50% 原始纤维、等离子体改性纤维或混合纤维的聚己二酸-对苯二甲酸丁二醇酯 (PBAT) 基复合材料，并进行彻底分析，以研究这些系统的加工-结构-性能关系。结果表明，结合等离子处理和 GO 涂层能够制造出机械性能显着提高的绿色复合材料（刚度和拉伸强度增量分别高达 500% 和 300%），电导率约为 10 S/m。
