Graphene-reinforced resin-based all-carbon composite material and preparation method thereof
The invention discloses a graphene-reinforced resin-based all-carbon composite material and a preparation method thereof. The preparation method comprises the following steps of: 1, soaking a carbon nanotube film in a hydrogen peroxide aqueous solution; soaking the film in a hydrochloric acid aqueous solution; washing the film, and carrying out mechanical one-way stretching; immersing the film ina first liquid; flushing the film with dichloromethane; performing vacuum standing to obtain a treated film; immersing the treated film into a second liquid; using a pulling method to perform pullingto obtain a layered structure; pressing the layered structure along the thickness direction of the layered structure under mechanical pressure with the temperature increasing from room temperature to180-200 DEG C during pressing; raising the temperature from room temperature to 1000 to 1100 DEG C in an inert gas or nitrogen environment and keeping the temperature for 30 minutes; and cooling a product to the room temperature so as to obtain the graphene-reinforced resin-based all-carbon composite material. According to the graphene-reinforced resin-based all-carbon composite material and the preparation method thereof, by designing the layered structure, pretreating a layer bonding surface, and applying a graphene filler, slow curing is performed; the close combination of a soft phase anda hard phase is utilized, so that the composite material is compact in texture, and high thermal conductivity of the composite material is realized.
本发明公开了一种石墨烯增强的树脂基全碳复合材料及其制备方法，制备方法包括以下步骤：将碳纳米管薄膜在过氧化氢水溶液中浸泡，再在盐酸水溶液中浸泡，冲洗，进行机械单向拉伸，沉浸在第一液体中，用二氯甲烷冲洗，真空静置，得到处理后薄膜，将处理后薄膜浸入第二液体中，再采用提拉法进行提拉，得到层状结构，再于机械压力下沿层状结构的厚度方向压制，压制时从室温升温至180～200℃，再在惰性气体或氮气环境下从室温升温至1000‑1100℃并于该温度保持30min，冷却至室温，得到石墨烯增强的树脂基全碳复合材料，本发明通过设计层状结构、层结合面的预处理、石墨烯填料的应用，缓慢固化，利用软相与硬相的紧密结合，使复合材料质地紧密，实现了高导热性。
