A Heat Sensitive Color-Developing Nanocapsule as Leucocompound Delivery Carrier

Article Preview

Abstract:

A heat sensitive color-developing nanocapsule as leucocompound delivery carrier was prepared by emulsion polymerization. The nanocapsules were characterized by Malvern particle size analysis, scanning electron microscopy (SEM) and UV/visible spectrophotometer. The heat sensitive color-developing curves of absorbency at different temperature were investigated. The effects of core/wall mass ratio on the heat sensitive color-developing properties of nanocapsules were discussed in detail. The particle size analysis demonstrates that the particle sizes mostly concentrate between 124 nm and 312 nm. SEM result shows that the nanocapsules have smooth surface. The resultant nanocapsules have the highest heat sensitive color-developing absorbency with the the core/wall mass ratio being 1:8.
