Study on Preparation Technology of Self-healing Micro-nano Capsule based on Calcium Alginate

Abstract

Micro/nano capsules embedment was an effective method to repair micro crack and mechanical damage. In this paper, preparation technology of self-healing micro-nano capsule based on calcium alginate was studied by in-situ method. And the rate of covering and particle size were investigated under different emulsifier dosages and core-wall ratios.
