Preparation and heat sensitive color-developing behaviour of poly (MMA-co-St) nanocapsules
Author(s): Haiyang Cui, Jinfang Wang and Puying An
Abstract: The heat sensitive color-developing poly(methylmethacrylate-co-styrene) (P(MMA-co-St)) nanocapsules were prepared by emulsion polymerization with leucocompound as a core material and P(MMA-co-St) as a wall material. The nanocapsules were characterized by scanning electron microscopy(SEM), Fourier transform infrared spectrophotometry (FTIR) and densitometry. The effects of St Content on the heat sensitive color-developing behaviours of nanocapsules were discussed in detail. The FTIR analysis of leucocompound-containing nanocapsules demonstrated that leucocompound was successfully encapsulated in the nanocapsules. The resultant nanocapsules at St content being 20wt% had smooth surface. The nanocapsules with different St content showed different heat sensitive color-developing behaviour.
