基于模板法制备两亲性Janus纳米粒子及其应用进展

Janus粒子是同一粒子中含有两种不同化学组成的非对称结构,其中两亲性Janus粒子是在对立面分别含有亲水基、疏水基两种不同化学基团,作为一种新型纳米材料受到广泛的关注。该文综述了模板法制备不对称结构的两亲性Janus粒子以及其应用领域,包括硬模板法、软模板法、牺牲模板法以及无模板法;综述了两亲性Janus粒子在表面活性剂、牙科粘合剂、微胶囊、功能涂层、催化剂以及生物传感器等方面的研究进展。

Preparation and Application of Amphiphilic Janus Nanoparticles Based on Template Method

Janus particles are asymmetric structures containing two different chemical compositions in the same particle. The amphiphilic Janus particles are two different chemical groups containing hydrophilic groups and hydrophobic groups on the opposite side, which is a new type of nanomaterial. In this paper, the amphiphilic Janus particles prepared by template method and their application fields are reviewed, including hard template method, soft template method, sacrificial template method and template-free method. The research progress of amphiphilic Janus particles in surfactants, dental adhesives, microcapsules, functional coatings, catalysts and biosensors are reviewed.
