| Abstract | Cellulose-originated three-dimensional graphene oxide CNT-modified LiOH center dot H2O (3D-GO-CNTs-LiOH center dot H2O) was synthesized by the hydrothermal method. LiOH center dot H2O nanoparticles (5-50 nm) were homogeneously dispersed inside the 3D-GO-CNTs frames. The composite showed enhanced heat storage density, excellent thermal conductivity, and greatly improved hydration rate due to both the hydrophilic reaction interface of 3D-GO-CNTs frames and reduced size of LiOH center dot H2O nanoparticles. LiOH center dot H2O content ratio of 23% (3D-GO-CNTs-LiOH center dot H2O-1) results in best heat storage performance with activation energy of 23.8 kJ/mol, thermal conductivity of 3.06 W/m center dot K, and heat storage capacity of 2800 kJ/kg. 3D-GO-CNTs-LiOH center dot H2O shows 4.2 folders heat storage capacity than that of pristine LiOH center dot H2O after the same hydration reaction. Other composite materials also show good performance: 3D-GO-CNTs-LiOH center dot H2O-2 (activation energy: 28.5 kJ/mol, thermal conductivity: 2.33 W/m center dot K, and heat storage capacity: 2051 kJ/kg.); 3D-GO-CNTs-LiOH center dot H2O-3 (activation energy: 32.3 kJ/mol, thermal conductivity: 2.01 W/m center dot K, and heat storage capacity: 1983 kJ/kg.). The addition of cellulose originated 3D-GO-CNTs was proved to be an excellent strategy to boost the heat storage performance of LiOH center dot H2O. |
