Abstract

The invention provides a benzoxazine / epoxy resin / graphene oxide composite material and a preparation method thereof. The ternary composite material reduces curing temperature and increases toughness. The method comprises the following steps: step 1, dissolving graphene oxide in a solvent to obtain a graphene oxide solution; step 2, adding epoxy resin to the graphene oxide solution obtained in step 1, stirring to disperse it evenly, and obtaining a ring Oxygen resin and graphene oxide mixed solution; Step 3, add benzoxazine intermediate in the epoxy resin and graphene oxide mixed solution that step 2 makes, stir to make it disperse evenly, make benzoxazine / ring Oxygen resin / graphene oxide mixture; step 4, drying the benzoxazine / epoxy resin / graphene oxide mixture obtained in step 3 to obtain a benzoxazine / epoxy resin / graphene oxide composite material.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof, in particular to a benzoxazine / epoxy resin / graphene oxide composite material and a preparation method thereof. Background technique [0002] Graphene is the first two-dimensional carbon atom crystal with a thickness of one atom realized, and it is also a filler for new nanocomposite materials with excellent performance. In recent years, graphene has caused a sensation in the chemical and physical circles because it turns two-dimensional materials from concept to reality. Graphene oxide is a two-dimensional nanocarbon material with abundant oxygen-containing groups on its surface. Graphene oxide is a sheet of graphite under the action of strong acid and strong oxidant, oxygen atoms enter the graphite layer to combine π electrons, and carbonyl, hydroxyl, carboxyl and carbon atoms in the carbon network are combined to form a covalently bonded graphite interlayer compound, and...
