The design of composite materials using environmentally compatible materials and adopting sustainable preparation techniques is very necessary for a better environment. The present study is a step towards developing an environmentally friendly alternative to foam-based composites. The aim of the study is to understand the effect of natural fibers from date palms on the property of foam biocomposites. We adopted an environmentally friendly method of compatibilization between the polymer and the fibers for better reinforcement. The compatibility was done by environmentally friendly physical modification using plasma treatment. Plasma treatment provides surface modification and is an economical solution for further processing. In fact, three types of interfaces have been created: (1) by the addition of maleic anhydride, (2) by the use of plasma-treated low-density polyethylene, (3) by the combination of maleic anhydride and plasma. The overall performance was best in the use of plasma treatment alone. The effect was carefully analyzed based on morphological, mechanical and thermal studies. Finally, a morphology–property correlation was established.

使用环境兼容的材料并采用可持续的制备技术来设计复合材料对于改善环境非常必要。本研究是朝着开发基于泡沫的复合材料的环保替代品迈出的一步。该研究的目的是了解枣椰子天然纤维对泡沫生物复合材料性能的影响。我们在聚合物和纤维之间采用了环保的增容方法，以实现更好的增强效果。通过使用等离子体处理的环境友好的物理修饰来实现兼容性。等离子处理可进行表面改性，是进一步加工的经济解决方案。实际上，已经创建了三种类型的界面：（1）通过添加马来酸酐，（2）通过使用等离子体处理的低密度聚乙烯，（3）通过马来酸酐和等离子体的组合。仅使用等离子体处理时，总体性能最佳。根据形态学，力学和热学研究仔细分析了这种影响。最后，建立了形态与属性的关联。
