Preparation and characterization of hexadecane microcapsule with polyurea--melamine formaldehyde resin shell materials

This paper gives a brief report of the preparation of hexadecane microcapsule with polyurea-melamine formaldehyde resin shell materials (HMPM). The sealing performance and thermal stability of HMPM was enhanced much more effectively than that of microcapsule with polyurea shell material (HPM). The results of microscopical imaging analysis system, DSC, TG, and laser particle analyzer were briefly introduced.
