摘要
综述了原子转移自由基聚合法、反向原子转移自由基聚合法、电子转移生成催化剂原子转移自由基聚合法、电子转移活化再生催化剂原子转移自由基聚合法在无机纳米粒子表面接枝聚合物的研究进展,介绍了聚合物接枝改性过程中不同催化体系的特点。采用上述方法在无机纳米粒子表面接枝改性,均能有效控制纳米复合粒子的粒径及其分布,提高纳米粒子的分散性、耐久性和相容性且反应条件简单、可控性强,是前景广阔的聚合方法。
The modification methods of grafting polymer on the surface of inorganic nanoparticles via a series of living polymerization include atom transfer radical polymerization(ATRP),reverse ATRP,activators generated by electron transfer ATRP and activators regenerated by electron transfer ATRP were introduced.The characteristics of different catalytic systems of surface modification via ATRP were described.The particle size and distribution of nanocomposites could be effectively controlled and the dispersibility,durability and compatibility of nanoparticles were improved after modification.In addition,the method was simple to reactionary condition and easily controlled,which was promised.
