Abstract :Phase change materials insert ignore into journalissuearticles values(PCMs); can store and release latent heat by making phase transitions between solid-solid or liquid-solid phases at specific temperature ranges. In the preparation of silk fibroin insert ignore into journalissuearticles values(SF); and chitosan insert ignore into journalissuearticles values(CHI); based phase change microcapsules and foam structures, the usage of virgin coconut oil insert ignore into journalissuearticles values(VCO); as a phase change agent was investigated, both forms were successfully prepared and characterized. Scanning Electron Microscope insert ignore into journalissuearticles values(SEM); and optical microscope with heating block analyzes were performed on microcapsules. SEM, Fourier-transform infrared spectroscopy, and differential scanning calorimeter analyzes were performed on foams. SF and CHI-based microcapsules had homogeneous size distribution and were thermally stable up to 60°C. Characteristic properties of the foam structures changed with the amounts of SF and CHI, and phase change occur at around 25°C, the melting temperature of VCO, resulting in energy absorption of 0.5287 W/g. Microcapsule and foam PCMs obtained can be used in different medical and thermoregulated textile applications.
