Carbon nanotube (CNT) was successfully introduced into chromophoric polymer phase change materials (PCM) to synthesize solar thermal conversion PCM with high thermal conductivity.X-ray diffraction,scanning electron microscopy and thermal conductivity tester,et al,were used to characterize the structure and thermal storage and transfer performance of the PCMs.The results shown that the thermal conductivity and solar thermal conversion efficiency of the PCMs were significantly improved with the addition of CNT.With the best CNT content (the mass ratio of CNT and PCM was 4∶100) in PCM,the solar thermal conversion efficiency of the CNT/PCM was as high as 89.93%,and the thermal conductivity was 0.405 W·m-1·k-1,which was significantly improved by 118.9% compared with pure PCM.
