Preparation of nanoencapsulated electronic ink by complex coacervation

In this paper, the nanoencapsulated electronic ink containing TiO₂ nanoparticles modified with stearic acid dispersed in tetrachloroethylene(TCE)were prepared by complex coacervation using gelatin-gum acacia as wall materials, and the factors effected the dispersion ability of suspension was discussed, and the nanoencapsulated electric inks were also prepared. The results showed the dispersion was able to be obtained by optimizing the factors. The nanocapsules prepared with uniform size distribution, and the TiO₂ nanoparticles were encapsulated in nanocapsules identified by TEM.
