Abstract

The invention provides a high-thermal-conductivity antibacterial composite material and a preparation method thereof. An epoxy resin modifier is obtained through the following steps: mixing epoxy resin, a silicone leveling agent, diaminodiphenyl methane, ethylene glycol and deionized water, performing low-speed stirring and mixing, then adding a directing agent, performing low-speed stirring and mixing, adding silver nanowires, and performing low-speed stirring and mixing, so as to obtain the epoxy resin modifier. The epoxy resin modifier is used for combination with a carbon fiber material, and then magnetron sputtering by zinc oxide is carried out, so that the thermal conductivity of carbon fiber is improved, also excellent antibacterial properties are provided, and better UV shielding performance is provided.
