요약
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 1HNMR
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.
