A one-step sequential method for preparing AgCl@polypyrrole-chitosan core-shell nanoparticles and subsequently the formation of polypyrrole-chitosan hollow nanospheres is reported. The formation of the core and the shell is performed in one reaction medium almost simultaneously. Transmission electron microscopy (TEM) images show the presence of core-shell nanoparticles and hollow nanospheres. Ultraviolet-visible (UV-vis) studies reveal that AgCl was formed first followed by polypyrrole. X-ray diffration (XRD) and UV-vis studies show that AgCl was present in the core-shell nanoparticles and could be removed completely from the core.
报道了一种制备AgCl@聚吡咯-壳聚糖核壳纳米粒子并随后形成聚吡咯-壳聚糖中空纳米球的一步连续法。核和壳的形成几乎在同一反应介质中同时进行。透射电子显微镜（TEM）图像显示了核壳纳米粒子和中空纳米球的存在。紫外可见（UV-vis）研究表明，首先形成AgCl，然后是聚吡咯。X射线衍射（XRD）和UV-vis研究表明，AgCl存在于核壳纳米粒子中，并且可以从核中完全去除。
