Highly innovative work towards development of a new class of materials called Multifunctional Polymers (MPs), such as selfhealing polymers, is in progress. This often refers to the ability ofa material to repair in an autonomic way. Microencapsulation is one of the techniques that reported in the literature [1].Ethylcellulose based microcapsule (ECM) is recently used in polymeric coating as the self-healing material. In this work, ECMwas modified using 3-(Methacryloyloxy)propyl]- trimethoxysilane coupling agent to enhance microcapsules sell via phase change separation (solvent evaporation) method
