| Abstract: | With n-butyl methacrylate（BMA） for the capsule core,melamine resin for polymer wall material,microcapsule with self-healing function was prepared by process of in situ polymerization.The diameter distribution,surface morphology,thermal properties and chemical structure of the microcapsules were investigated by means of laser particle size analyzer,optical microscope,microcomputer differential thermal balance and FT-IR,respectively.Meanwhile,the influence of emulsifying agent,stirring speed and the ratio of core material to wall material on the preparation of microcapsules were discussed.Results indicated that the highest loading of BMA in the resultant microcapsules could be about 80 wt% and average particle size of the capsules fell in the range of 40～80 €%em,which could be adjusted by changing processing parameters. |
