Abstract Scope |
Porous titanium dioxide ceramic (PTC) with uniform, controllable, 3D fully interconnected pore structure and high porosities were prepared by a facile particle-stabilized emulsion templating method, and adjustable pore structure of PTCs could be obtained by controlling its solid content from 20 to 35 wt. %. Specifically, PTC was featured by large cavities connected by small-sized windows on the wall. The large cavities endow the PTC with large capability for impregnating PCMs, and the small windows make the leakage of impregnated PCM difficult. Moreover, its strength and porosity can be tailored. The study showed that the three-dimensional interconnected tailored pore structure and high porosities had positive effects on improving the thermal storage capacity and thermal properties of PCMs, PTC is a promising carrier material for High temperature energy storage. |
