Abstract

Phase change microcapsules have a wide range of applications, but as a type of microplastic, they pose a certain environmental pollution risk. In this article, we prepared degradable lactic-acid-based phase change microcapsules by using PLA diol (PLA-500)-modified IPDI and BDO as wall materials and n-octadecane as the core material via an interfacial polymerization method. The optimal process cond…
