Interface Design and Application Research of Functionalized Fillers Reinforced Polypropylene Composite Materials

摘要

聚丙烯因其加工性能良好与成本优势，在工程材料领域得到广泛应用，但其界面相容性不足制约了复合材料性能提升。功能化填料的引入为界面结构优化提供了新的路径，通过表面改性与界面设计，可在分子层面增强界面结合，实现性能协同提升。本文围绕功能化填料在聚丙烯复合材料中的作用机理，从界面结构演化、填料功能化方式及性能调控规律等方面进行系统分析，并结合典型应用探讨界面设计策略。研究表明，合理构建界面过渡层并调控界面相互作用，可显著改善力学性能与热稳定性，为高性能聚丙烯复合材料开发提供参考。

Abstract

Polypropylene has been widely utilized in engineering materials due to its excellent processability and cost advantages. However, insufficient interfacial compatibility remains a limiting factor for enhancing composite material performance. The introduction of functionalized fillers offers a novel approach to optimize interfacial structures. Through surface modification and interfacial design, molecular-level interfacial bonding can be strengthened to achieve synergistic performance improvements. This study systematically analyzes the mechanisms of functionalized fillers in polypropylene composites, focusing on interfacial structure evolution, filler functionalization methods, and performance modulation patterns. Typical applications are also employed to explore interfacial design strategies. Research findings demonstrate that rational construction of interfacial transition layers and controlled interfacial interactions significantly improve mechanical properties and thermal stability, providing valuable insights for developing high-performance polypropylene composites.
