Embodiment 1
[0021] Specifically include the following steps:
[0022] (1) Prepare a 3mol / L hydrochloric acid solution, calcinate the glass fiber at 450°C for 1 hour, soak in the hydrochloric acid solution to hydroxylate the surface of the glass fiber, reduce the contact angle between the glass and water, and complete the modification of the glass. The optimal process is 3mol / L acid solution treatment for 70min, and the contact angle is 21°.
[0023] (2) Configure γ-aminopropyltrimethoxysilane (KH550) with a mass fraction of 1%. The glass fibers obtained after soaking in an alcohol solution with a modifier of silane coupling agent (KH550) at a concentration of 1.0wt.% for 30 minutes after acid treatment. The modification results show that after modification, the contact angle with water becomes larger, and the hydrophilicity of the glass material decreases; when the mass fraction of coupling agent is less than 1.0%, the contact angle increases with the increase of the concentration, and t...

The invention belongs to the technical field of material preparation, and particularly relates to a preparation method of graphene-coated glass fiber reinforced plastic. The method comprises the following steps: glass fiber reinforced plastic surface treatment. The glass material surface treatment mainly comprises three steps of hydroxylation of the surface of glass fiber,silane coupling agent modification and self-assembly of bovine serum albumin, and the pretreatment of the glass fiber is completed through the three steps, so that the bonding performance of the glass fiber and graphene oxideis enhanced; the graphene oxide is self-assembled on the surface of the modified glass fiber to form a graphene oxide film. According to the invention, the graphene is used for winding the modified glass fiber, and a carbon conductive network is formed in the composite material, so that the composite material has an electric energy shielding function, and the modified glass fiber reinforced plastic wound graphene composite material has good mechanical properties such as compression resistance, tensile strength and the like.

technical field [0001] The invention belongs to the technical field of material preparation, and in particular relates to a preparation method of graphene-coated FRP. Background technique [0002] Graphene is a carbon atom with sp 2 The hybrid orbitals form a hexagonal two-dimensional carbon nanomaterial with a honeycomb lattice. Graphene has excellent optical, electrical, and mechanical properties. At present, many materials are prepared by preparing graphene-based composite materials, using the high conductivity of graphene, in order to expect to obtain conductive materials with excellent performance. FRP has good mechanical properties, heat resistance and corrosion resistance, and is widely used in transportation, construction, and electronic technology. However, due to its poor electrical conductivity, FRP is difficult to apply in the field of electromagnetic shielding. In order to enhance the conductivity of FRP and expand the application of FRP in electromagnetic shi...
