摘　　要：通过乳液聚合合成一系列含金属离子的聚丙烯酸酯乳液,得到含金属离子的聚丙烯酸酯自修复膜材料。该材料利用单体丙烯酰胺上的酰胺官能团与金属离子Cr^(3+)进行配位,并且单体丙烯酰胺上的酰胺基团可以形成具有可逆作用的氢键,形成金属配位键和氢键双重动态可逆作用的自修复聚丙烯酸酯膜材料。研究发现加入金属离子后薄膜具有自我修复能力,金属离子含量不同时其修复效果也不同。研究了薄膜的最佳自修复温度和最佳自修复时间,实验结果表明,金属离子含量为0.15 g时,聚合物的拉伸强度修复率最高可达80%;薄膜最佳自修复时间为12 h,薄膜最佳自修复温度为60℃。利用聚合物中特殊官能团与金属离子配位作用,赋予了自修复材料优异的机械性能和修复性能。The self-repair properties of polyacrylate membrane material were mainly realized through the dual dynamic reversible effect of metal coordination bond and hydrogen bond.A series of polyacrylate emulsions containing metal ions were synthesized through emulsion polymerization.The self-healing polyacrylate membrane material containing metal ions was coordinated with metal ions Cr^(3+)by the functional group(amide group)on the monomer acrylamide,and the functional group(amide group)on the monomer acrylamide could form reversible hydrogen bonds.It is found that the film has self-healing ability after adding metal ions,and the repair effect is different with different content of metal ions.The best self-healing temperature and the best self-healing time of the film were studied.The tensile test shows that when the content of metal ions was 0.15 g,the tensile strength repair rate of the polymer was up to 80%.The best self-healing time of the film was 12 h,and the best self-healing temperature was 60℃.The coordination of metal ions and special functional groups in polymers has made the self-healing materials have excellent mechanical properties and good repair performances.
