Starch nanoparticles have been prepared with W/O starch microemulsion as microreader and epichlorohydrin as cross-linking agent. The factors affecting the preparation of SN have been investigated via the characterization of TEM. The results show that the size and size distribution of SN are mainly controlled by the interfacial strength of microreactor, and the interfacial strength of microreactor is chiefly influenced by W value (the molar ratio of water / surfactant) and concentration of starch. The SN with controllable size and size distribution can be obtained by adjusting preparation parameters.

利用所得到的W／O型淀粉微乳液作为微型反应器，以环氧氯丙烷为交联剂制备出淀粉纳米粒，并借助透射电镜的表征研究了各制备因素的影响，研究结果表明：淀粉纳米粒的粒径及粒度分布主要受微型反应器的界面强度控制，而影响界面强度的因素主要是R值(即水与表面活性剂的摩尔比值)及淀粉液浓度。
