Nanofiber-reinforced polymer composites exhibit excellent mechanical properties and functionality in the field of modern materials, and are widely used in industrial fields such as aerospace and automotive. Their interface modification is a key factor in improving material performance. This paper studies the dispersibility, interface interaction and modification mechanism of nanofibers in polymer matrices. The compatibility between nanofibers and polymer matrices is improved through surface modification technology, which effectively enhances the mechanical strength and thermal stability of the composites. The influence of nanofiber surface modification methods on the performance of composites is mainly reflected in enhancing interface bonding force, reducing interface stress concentration, and improving dispersibility. Experimental verification shows that the surface modification of nanofibers significantly improves the comprehensive performance of the composites, providing an important theoretical basis for the development of composites in the future.
