摘要

Abstract

A facile and efficient method has been developed for microencapsulation of metal oxide nanoparticles in polyurea

via

interfacial polymerization of toluene-2

4-diisocyanate and H

O through the atomizing emulsification approach.The resultant microcapsules were well-shaped and uniform sphere with diameter ranging from 2 to 6 μm.Thermogravimetry(TG)and differential scanning calorimetry(DSC)curves revealed that the microcapsules showed good thermal stability(no decomposition observed under 245℃).Besides

the microencapsulated TiO

has been used as an efficient catalyst for photocatalytic degradation of methyl orange.Furthermore

the photocatalysis of immobilized TiO

could be enhanced by introducing UV absorbing agent to the wall of microcapsules.
