| 英文摘要 | Inorganic phase change materials (PCM) with relatively high thermal storage capacity and low cost suffer from serious leakge, supercooling and low thermal conductivity, impeding its large-scale application. Herein, hybrid dimensional carbon nanomaterials including carbon nanofiber and graphene, was adopted ot tackle these issues. Furthermore, modified lotus root starch was employed to enhance the overall thermal storage capacity of the composite PCM. The comprehensive properties of the composite PCM were characterized by the technology of SEM, XRD, FT-IR, hot disk, viscometer, DSC, TGA, DFT calculation method. The results show than with the addition of hybrid dimensional carbon nanomaterials, semi -crystallization time of NaCH 3 COO . 3H 2 O- Na 2 S 2 O 3 . 5H 2 O/hybrid dimensional carbon nanomaterials composite PCM decreased from 0.96 min to 0.78 min, indicating the substantial supercooling mitigiation of hybrid dimensional carbon nanomaterials. Meanwhile, the addition of hybrid dimensional carbon nanomaterials also improve the thermal conductivity of the composite PCM to 1.403 W/(m . K), 2.5 times of that of NaCH 3 COO . 3H 2 O-Na 2 S 2 O 3 . 5H 2 O eutectic. It is worth noting that the addition of modified lotus root starch increased the maximum enthalpy of the composite PCM by 9.1%. The more hygrogen bonds of the composite which can improve the PCM-holding capacity, are responsible for this enthalpy increase. The study results can provide new insight on the high-performance inorganic PCM preparation and large-scale application. |
