Carbon-polymer structure with photo-thermal effect and heat-conducting property as well as preparation method and application thereof

Abstract

The invention discloses a carbon-polymer structure with a photo-thermal effect and heat-conducting property as well as a preparation method and application thereof. The preparation method comprises the following steps: preparing multiple optical fibers, weaving a plurality of b-section optical fibers together to form a heat dissipation structure; repeating a coating thickness regulation and control method on the heat dissipation structure for 1-15 times to obtain an optical fiber network connected to an a-section optical fiber bundle; putting the optical fiber network into a mixture B, processing for 5-60 minutes under an absolute pressure intensity of 0.001-90KPa, and then taking out the processed optical fiber network out of the mixture B (or curing the processed optical fiber network and the mixture B for 1-4 hours under a normal pressure of 60-200 DEG C to obtain the carbon-polymer structure). The carbon-polymer structure is ingenious in design and simple in preparation method, thecarbon nano material coating on the surface of the optical fiber network can absorb light energy emitted by the optical fibers and convert the light energy into heat energy, the polymer matrix containing a heat conduction filler can rapidly transfer heat to the surface layer of the carbon-polymer structure, and heating or warming of a specific space is achieved.
