Abstract

In an encapsulation system with functional core materials, it is important to enhance the mechanical and thermal stabilities of the microcapsules to sustain their properties in the matrix polymer. In this study, poly(melamine-urea-formaldehyde) (MUF) microcapsules were prepared by in-situ polymerization in an oil-in-water emulsion. Then, the microcapsules were rewrapped with melamine-urea-formaldehyde and silica to form multiwalled organic/inorganic hybrid microcapsules. From the combined results of 1H-NMR imaging, FT-IR spectroscopy, TGA, and SEM-EDX, it was found that the microcapsules have highly enhanced mechanical durabilities. In addition, when introduced into silicone rubber composites, the microcapsules were observed to be well dispersed and result in mechanical improvement of the composite owing to the rigid inorganic surface of the microcapsule. This enables the possibility of creating functional composites with high durabilities.
