摘要

聚丙烯（PP）基复合材料因其优异的物理化学性能而被广泛应用于工业领域。然而，聚丙烯的脆性是其应用的主要限制因素。为了提高其韧性和耐冲击性，研究人员通过多种方法对聚丙烯进行增韧改性。本文综述了聚丙烯基复合材料的增韧改性方法，包括无机填料改性、有机高分子增韧剂以及共混改性等技术，探讨了这些方法对聚丙烯性能的影响。研究结果表明，通过适当的增韧改性手段，可以显著提高聚丙烯复合材料的力学性能，尤其是其冲击韧性和耐用性。最后，本文分析了聚丙烯增韧改性的发展趋势，并对未来的研究方向进行了展望。

Abstract

Polypropylene (PP) composites have been widely adopted in industrial applications due to their superior physical and chemical properties. However, the brittleness of polypropylene remains a major limitation in practical applications. To enhance its toughness and impact resistance, researchers have implemented various toughening modification methods. This paper reviews the techniques for toughening polypropylene composites, including inorganic filler modification, organic polymer toughening agents, and blending modification, while analyzing their effects on material performance. The findings demonstrate that appropriate toughening approaches can significantly improve the mechanical properties of polypropylene composites, particularly in terms of impact toughness and durability. Finally, the paper examines the development trends in polypropylene toughening modification and outlines future research directions.
