九十年代以来，人们对纳米材料的制备、应用及研究越来越多［１］，纳米材料的制备技术也日趋成熟。纳米材料制备科学中所追求的是颗粒度小，粒径均匀，分散性好的合成方法。本文选用表面修饰法合成了表面修饰ＰｂＳ纳米颗粒，该法是以类高分子聚合的竞争反应为基础，在无... Since the nineties, people have more and more of preparation, application and research of nanomaterials [1], nanomaterials preparation technology is also maturing. Nanoscale material preparation science is pursued by the particle size is small, uniform size, good dispersion synthesis method. In this paper, the surface modification of surface-modified PbS nanoparticles were synthesized, the method is based on the competitive polymer-based polymerization reaction based on the ...
