Functionalization of linseed oil-filled microcapsules with PMMA shell by using HMDA for self healing application

In this study, microcapsules containing linseed oil (LO) and with polymethyl methacrylate (PMMA) shell were prepared by solvent evaporation method. The yield of microcapsulation and the oil content of microcapsules were obtained about 65-87% and 70%, respectively. Surface modification of PMMA microcapsules was performed byHDMA in order to create functional groups that was detected by FTIR. Optical microscopy indicated a spherical morphology for micrcapsules with mean size of 5 μm and 50 μm at 1000 and 600 rpm, respectively
