MULTI-WALLED CARBON NANOTUBE COMPOSITE FORM-STABLE PHASE CHANGE MATERIAL, AND PREPARATION METHOD AND USE THEREFOR

摘要

A multi-walled carbon nanotube composite form-stable phase change material and a preparation method and a use therefor. The multi-walled carbon nanotube composite form-stable phase change material is prepared from multi-walled carbon nanotubes at a weight percent of 16.7-83.3 wt%, a phase change material of 16.7-83.3 wt%, and a biodegradable material of 0-16.7 wt% by means of physical blending. The composite form-stable phase change material features an excellent high-temperature resistance, exhibits solid-solid phase change features, and is able to maintain a stable form under high temperatures. The phase transition of the phase change material from a crystal state to an amorphous state causes the material to have a heat absorption and energy storage function. The excellent thermal conductivity of the multi-walled carbon nanotubes themselves is able to allow the material to achieve the effect of rapid heat absorption and temperature reduction.
