ZnO functionalized paraffin/diatomite phase change material and its thermal management mechanism in PDMS coatings.

ABSTRACT: The functionalization of conventional diatomite/paraffin phase change materials is of great significance to expand its application in thermal management. Herein, a nano-ZnO functionalized paraffin/diatomite phase change material (PA/F-DE/ZnO) with enhanced thermal conductivity, anti-leakage and UV-adsorption was prepared by simple melt blending and adsorption. The results indicated that when nano-ZnO was introduced to PA₁/F-DE (mass ratio is 1 : 1) system, the obtained PA/F-DE/ZnO not only possessed enhanced thermal conductivity and reduced leakage but also presented excellent UV absorption performance and retained the heat storage performance well. The thermal conductivity of PA₁/F-DE/ZnO₁₀ (with 10 wt% of ZnO) is enhanced by 87.73% compared with that of P
