Preparation and characterization of melamine-urea-formaldehydemicrocapsules containing methacryloxy propyl terminated polydimethylsiloxane

In this work methacryloxy propyl terminated polydimethylsiloxane (MAT-PDMS), as a light cure healing agent, was encapsulated with a melamine-urea-formaldehyde (MUF) shell fabricated by in-situ polymerization. A polyvinylpyrrolidone (PVP) was used to stabilize the dispersion. The chemical structures of core, shell and microcapsules were determined by using FTIR analysis. The morphology of the prepared microcapsules was studied by using a scanning electron microscope (SEM). Thermo gravimetric analysis (TGA) was used to evaluate the thermal stability of samples
