FABRICATION OF MICROENCAPSULATED PCMs WITH NANOCLAY DOPED CHITOSAN SHELL AND THEIR APPLICATION TO COTTON FABRIC

Abstract

In this study, preparation of composite microcapsules with clay nano particles (CNPs) doped chitosan shell and paraffin core was carried out by oil-in-water (o/w) complex coacervation method. It was aimed to microencapsulate phase change materials (PCMs) within composite shell material composed of organic and inorganic components. The effect of surface active materials having different hydrophilic/lipophilic balance (HLB) on preparation and properties of the microcapsules was also investigated. Thermal properties, morphology, chemical structure of the prepared microcapsules containing PCMs (MicroPCMs) were analyzed by differential scanning calorimeter (DSC), Thermogravimetric analysis (TGA), optical microcopy, and Fourier transform infrared (FT-IR) spectroscopy, respectively. The thermo-regulation effect of the MicroPCMs on the cotton fabric was investigated
