光控偶氮苯与木材复合相变材料的能量储存与释放
Energy Storage and Release in Optically Controlled Azobenzene and Wood Composite Phase Change Materials
摘要
Abstract
Under specific wavelengths of light irradiation,azobenzene can undergo reversible cis-trans configuration isomerization and release heat.However,it still suffers from problems such as slow isomerization rate,low energy storage density,and easy leakage,which limit its practical applications.To address these issues,tetradecyloxyazobenzene(T-ZAO)and tetra-decanol(TD)were mixed at different molar ratios,impregnated into delignified balsa wood,and the morphology,light-controlled performance,energy storage density,and photoinduced isomerization characteristics of the composite materials were determined.The results showed that delignified wood serves as an effective supporting matrix.The optimal molar do-ping ratio of azobenzene was 10%,with a supercooling degree of 3.8 ℃,which could realize light-controlled energy release and an energy storage density of 185.5 J·g-1.The charging time was 40 min and the discharging time was 15 min,accom-panied by excellent cyclic stability.In conclusion,the composite material possesses both efficient light-controlled phase change energy storage and thermal management capabilities,providing a feasible approach for the development of novel in-telligent energy-storing wood materials.关键词
