摘要
目的制备PbS纳米粒子。方法利用由苯乙烯(st)与丙稀酸叔丁酯(t-BA)的聚合反应制得无规共聚物P(St-tBA)水解得到的两亲型无规共聚物聚苯乙烯-丙烯酸(P(St-AA))为添加剂,采用溶剂热法制备了PbS纳米粒子。结果通过溶剂热法制备了多种形貌的PbS纳米粒子并用透射电镜(TEM)观察了其形貌。结论通过溶剂热法可以制备多种形貌的PbS纳米粒子,聚合物P(St-AA)加入量、溶剂等对PbS纳米粒子的形貌有影响。
Objective: To prepare PbS nano-crystalline powders. Methods: With amphiphihc random copolymer of polystyrene-acrylic acid (PSt-AA) which was prepared by the hydrolysis of P(St-tBA) synthesized by the random polymerization of styrene and tert-butyl methacrylate as additive, PbS nano-crystalline powders was fabricated by a solvo- thermal approach. Results: PbS nano-crystalline powders with different morphology were prepared and its morphology was investigated by transmission electron microscope ( TEM ). Conclusion : PbS nano-crystalline powders with different morphology can be fabricated by a solvothermal approach and its morphology was affected by the level of PSt-AA. and the category of solvent.
