The Effects of Synthesis Conditions on PUF Microcapsule Morphology

Abstract:

In this paper, self-healing PUF microcapsules were prepared by in situ polymerization. The test results show that: 1) the ratio of core/wall material can had a significant effect on the average particle size of microcapsules. The ratio happens to be 1.0 to 1.0, best coating, relatively dense surface can be achieved. When the ratio reaches 1.4 to 1.0, the microcapsules have worst coating, particle size, distribution of wide range, and comparatively rough surface. When the ratio is 0.8 to 1.0 or 1.2 to 1.0, preferable coating, uniform particle size and its distribution, as well as smooth and dense surface can be obtained. 2) The faster the stirring speed, the smaller the particle size of microcapsule will be. And the size becomes bigger and varied with the stirring speed decreasing.
