Abstract

The invention discloses a bucky paper electrocaloric effect-based fusion method and a composite material thereof. The fusion method comprises following steps: bucky paper is contacted with a base material used for hot melting, and then is electrified and heated, and cooled and shaped. The composite material prepared by using the fusion method has a fusion structure of the base material and bucky paper. Full advantage of the excellent bucky paper electrocaloric effect is taken; the fusion method is simple; no pollution is caused; energy consumption is less; and preparation speed is fast. The dispersity of the composite material and carbon nano-materials (carbon nano-tube, carbon nanofiber, and graphene) prepared by the fusion method is high.

Description

technical field [0001] The invention relates to the application field of carbon nano paper, in particular to a bonding method based on the electrothermal effect of carbon nano paper and a composite material thereof. Background technique [0002] Carbon nanotubes and carbon nanofibers are often added to other materials to make carbon nano-reinforced materials because of their one-dimensional nanoscale structure, light weight, excellent electrical and thermal conductivity, and excellent mechanical strength. For example, mixed with organic polymers to make carbon nano-organic composite materials, its performance is comparable to that of the original polymer, while its weight is still very light. Organic composite materials doped with carbon nanotubes or carbon nanofibers can be widely used in fields such as electromagnetic shielding, high vibration damping materials, and high-conductivity high-strength polymer fibers. For example, the open journal Materials Science and Enginee...
