Abstract Scope |
The energy storage technology has developed unprecedentedly due to the establishment of environmentally-friendly society. Hydrated salts inorganic PCM has become a research hotspot because of its outstanding heat capacity, adjustable phase temperature and high availability. However, the critical drawbacks of low thermal enthalpy, liquid leakage problem and phase separation limit its further development. In this work, the flaky modified vermiculite (MEVM) was obtained by chemical exfoliation, and the cured lotus root starch (CLRS) was selected as functional additives. Results showed that the pakaging capacity of flaky EVM improved 23.7%. After 2 wt.% CLRS addition, the thermal enthalpy of SAT-CLRS/MEVM reached 180.1 J/g. The contact angle obetween the sample and H2O was 22.24゜, represented good hydrophilicity. In addition, Gaussian 16 and Multiwfn software calculated the weak interaction between SAT and CLRS. This work provides a new perspective for regulating the phase change behavior of inorganic hydrated salts. |
