介绍了核壳型乳胶粒子的基本形态结构和常用的表征手段,详细说明了用透射电子显微镜(TEM)表征核壳型乳胶粒子结构的两种情况,即分析透射电子显微镜法、普通透射电子显微镜法(免染色法和选择性染色法),并给出了它们的适用范围。分析透射电子显微镜适合表征所有类型的核壳型乳胶粒子,免染色法只适合表征乳胶粒内各组分对电子束散射能力差别较大的体系,选择性染色法适合于染色试剂能够使乳胶粒子的某一组分发生化学反应的情况。相关的研究者可以根据自己研究体系的具体情况和表征手段的条件,选择用哪种方法来表征乳胶粒子的核壳结构。为从事相关研究的工作者准确地证明乳胶粒子是否确实具有核壳结构提供有益的帮助。
The basic morphological structure and common characterization methods of core-shell latex particles are introduced. Two cases of characterization of core-shell latex particles by transmission electron microscopy (TEM) are described in detail, that is, transmission electron microscopy, transmission electron microscopy Method (free staining method and selective staining method), and gives their scope of application. Analysis of transmission electron microscopy is suitable for characterization of all types of core-shell latex particles. The non-staining method is only suitable for characterizing the system with different components of the latex particles on the electron beam scattering ability. The selective dyeing method is suitable for the dyeing reagent to make the latex particles The chemical reaction of a certain component of the situation. Relevant researchers can choose which method to characterize the core-shell structure of latex particles according to the specific conditions of their own research system and the means of characterization. It provides useful help for the workers engaged in relevant research to accurately prove whether the latex particles do have the core-shell structure.
