Abstract
In this study, the self-healing epoxy-filled microcapsules were synthesized using solvent evaporation technique. Poly(methylmethacrylate) (PMMA) was chosen as a shell material. The size of self-healing microcapsules was controlled by amending the sodium dodecyl sulphate (SDS) emulsifier concentration and agitation speed during the synthesis. The morphology, core content and molecular architecture of microcapsules were characterized by FESEM, solvent extraction technique and FTIR spectroscopy respectively. For microcapsules, the reduced size and shell wall thickness with enhanced core content showed a noticeable improvement escalating their potential use as self-healing agent in polymer composites.
