Rice husk natural fiber remains a highly abundant, eco-friendly and low-cost reinforcement filler for plastic composites fabrication. Hampered by its low aspect ratio and incompatibility with non-polar polymers, its utilization in reinforcing polymer composites often results in decreased composite properties such as decreased tensile strength, impact strength, percentage elongation, and flexural strength. However, stiffness increases. Various surface treatment techniques such as mercerization, compatibilization, acetylation, electron beam irradiation and plasma surface modification have been employed to improve its compatibility with non-polar matrix polymers. This article critically reviews the influence of these surface modification techniques on the resulting composite properties. Based on the analysis of reinforcing efficiencies of these techniques, their strengths, weaknesses, opportunities, and threats, the authors, therefore, project plasma treatment as the most efficient and eco-friendly technique with prospects for high technological application of rice husk plastic composites.

不同表面处理技术对掺入稻壳的聚合物复合材料性能的影响

稻壳天然纤维仍然是用于塑料复合材料制造的高度丰富，环保和低成本的增强填料。由于其低的长径比和与非极性聚合物的不相容性受到阻碍，其在增强聚合物复合材料中的应用常常导致复合材料性能下降，例如抗张强度，冲击强度，伸长率和挠曲强度降低。但是，刚度增加。已经采用了各种表面处理技术，例如丝光处理，相容化，乙酰化，电子束辐照和等离子体表面改性，以改善其与非极性基质聚合物的相容性。本文严格审查了这些表面改性技术对所得复合材料性能的影响。
