Article Preview

Composite thermochromic energy-storage materials (CTEM)were prepared by sol-gel method, Factors exerting influence on thermochomic and thermal properties of composite materials were discussed, such as the molar ratio of ester to water, the dosage of thermochomic materials, pH value were optimized via 3 factors and 3 levels of L9 (33) orthogonal design. Based on the research,when the molar ratio of ester to water was 1:7, dosage of thermochomic materials was 14g, pH value was 3, the optimal chromatic aberration and cooling time of the composite thermochromic energy-storage materials was successfully acquired. Results showed that the thermochomic materials were firmly enwrapped in silica of three-dimensional network structure, solving the problem of liquid release in the process of phase change and increasing its applications in textile, meanwhile it also had excellent thermochomic and thermal performance.
