聚乳酸(PLA)作为可降解材料受到广泛关注,但其力学性能仍不能全面满足实际应用需求。纳米材料复合促进结晶度提高是实现高分子材料高性能化的重要途径,而纳米填料的均匀分散和良好相容是其关键因素。采用固相力化学方法实现了碳纳米管(CNTs)在PLA基体中反应接枝及均匀分散,提高了PLA/CNTs复合材料的结晶度,为PLA基复合材料高性能化提供了新路径。
As a degradable material,polylactic acid (PLA) has received widespread attention though。but its mechanical properties cannot fully meet the needs of practical applications.Incorporation of nanomaterials to promote crystallinity paves an important way to achieve high performance of polymer materials,and the uniform dispersion and good compatibility of nanofillers are the key factors.The solid phase mechanochemical method was used to realize the in-situ grafting and uniform dispersion of carbon nanotubes (CNTs) in the PLA matrix,which successfully improved the crystallinity of the PLA/CNTs composite material.A new path to achieve high performance polylactic acid-based composite materials was provided.
