木塑复合材料(WPC)因结合植物纤维和热塑性塑料的特质,兼具优异性能与环保特性。但界面相容性差、功能性不足等问题制约其高附加值应用,因此对其进行改性具有重要意义。单一改性难以同步解决界面、力学及功能等多重问题,而协同改性通过多组分、多机制的协同突破单一体系局限,是提升其综合性能的关键。综述典型协同体系的作用机制,以及协同改性对WPC界面相容性、力学性能及功能性增强的影响规律,针对当前研究存在的环境友好型改性体系开发滞后、多组分协同效应调控规律不明晰等问题,展望了协同改性WPC的发展前景,旨在为推动高附加值、高性能WPC的研究提供科学理论依据。
Wood-plastic composites (WPCs),by combining the characteristics of plant fibers and thermoplastic plastics,exhibit excellent performance and environmental protection properties.However,issues such as poor interface compatibility and insufficient functionality restrict their high-value-added applications,making their modification significantly important.Single modification method struggles to simultaneously address multiple challenges related to interface,mechanics,and functionality.In contrast,synergistic modification,leveraging the synergistic effects of multiple components and mechanisms,breaks through the limitations of single systems and has become the key to enhancing the comprehensive performance of WPCs.This paper systematically reviewed the action mechanisms of typical synergistic systems,as well as the influence rules of synergistic modification on the improvement of interface compatibility,mechanical properties,and functionality of WPCs.Aiming at the existing problems in current research,such as the delayed development of environmentally friendly modification systems and the unclear regulation rules of multi-component synergistic effects,it discussed the development trends of synergistically modification of WPCs,providing a scientific theoretical basis for promoting the research on high-value-added and high-performance WPCs.
