Abstract

The present invention discloses a carbon pyrine polymer structure and preparation methods and applications with light thermal effects and thermal conductivity.Then repeat the thickness of the heat dissipation structure 1-15 times, get the fiber network connected to the fiber bouquet of sections A, place the fiber optic network in a mixture B, treat 5-60min under the absolute pressure of 0.001 to 90kPa, and thenThe processed optical fiber network is taken out of the mixture B or solidified for 1 to 4h under the normal pressure of 60 to 200 ° C with a mixture B to obtain the carbon pyrine polymer structure.The design of the carbon pupa polymer of the present invention is clever and simple to prepare. The carbon nanoma coating on the surface of the fiber network can absorb the optical energy emitted by the fiber and convert it into heat energy. The polymer with the heating filler can quickly pass the heat to the carbon ‑ ‑ ‑ ‑ 本 本 本The surface layer of the polymer structure realizes heating or heating of specific space.

Description

technical field [0001] The invention belongs to the technical field of photothermal and thermally conductive composite materials, and in particular relates to a carbon-polymer structure with photothermal effect and thermal conductivity, and a preparation method and application thereof. Background technique [0002] Solar energy refers to the thermal radiant energy of the sun. In modern times, it is generally used for photovoltaic power generation or to provide energy for water heaters. However, there are problems such as high cost, low conversion rate, and limited application. Efficient use of solar energy for heating is an important direction for the development and utilization of solar energy in the future. [0003] Carbon nanomaterials (including carbon nanotubes, carbon nanofibers, graphene, etc.) have good photothermal effects and can continue to generate heat under the action of sunlight, especially near-infrared light. Carbon nanomaterials are usually self-assembled ...
