A design and optimization of photo-thermal energy conversion components using textile fiber is very important in solar thermal energy conversion technology. In this study, an innovative bionic photo-thermal energy conversion model based on polar bears hair (Ursus maritimus) energy conversion mechanism has been explored and optimized. Besides, a processing technology and wave guiding principle using this new model were investigated to enhance the solar-thermal energy utilization property. Specifically, the fluorescent property, reflectivity and photo-thermal conversion property of the selected fabricating materials were measured and demonstrated in detail. The experimental results showed that this proposed new model worked well to design high-efficiency photo-thermal energy conversion devices. Also the bionic materials exhibited a high photo-thermal converting efficiency as well as outstanding heat insulation properties.
