Embodiment

[0012] Add 0.02 g of graphene to 80 ml of N-methylpyrrolidone, ultrasonically disperse for 45 min, then add 0.0037 g of zinc acetate, 0.0392 g of 3,4,9,10-perylenetetracarboxylic dianhydride and 0.0242 g of trihydroxymethylamino Methane, continue to ultrasonically disperse for 45 minutes, and then react at 180°C for 12 hours under a nitrogen atmosphere. After the reaction is completed, pour the reaction solution into absolute ethanol to precipitate the material, filter, and vacuum-dry the obtained filtrate to obtain a purple-black product , that is, perylene anhydride non-covalently modified graphene.

Abstract

The invention discloses a preparation method and application of perylene non-covalently modified graphene. The preparation method comprises the following steps: adding 0.02g of graphene in 80mL of N-methylpyrrolidone, carrying out ultrasonic dispersion for 0.5-1h, then adding 0.0037g of zinc acetate, 0.0392g of 3,4,9,10-Perylenetetracarboxylic dianhydride and 0.0242g of trihydroxymethyl aminomethane, continuously carrying out ultrasonic dispersion for 0.5-1h, then carrying out reaction for 10-14h at the temperature of 180 DEG C at the nitrogen atmosphere, pouring a reaction liquid in anhydrous alcohol to carry out precipitation and material discharge after reaction is finished, filtering a product, and vacuum drying an obtained filtrate to obtain a purple-black product, i.e. the perylene non-covalently modified graphene. The perylene non-covalently modified graphene can be applied to the technical field of epoxy resin-based composite or high-performance shape-memory polymer preparation. The preparation method and the application are very simple in preparation process and are liable to popularize; and in addition, the prepared perylene non-covalently modified graphene can be used for preparing the epoxy resin-based composite and high-performance shape-memory polymer and fully utilizes the synergetic enhancement effect of perylene and graphene in performance.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification, in particular to a preparation method and application of perylene anhydride non-covalently modified graphene. Background technique [0002] Graphene is a new carbon material with a single-layer two-dimensional honeycomb lattice structure formed by densely packed carbon atoms. It has a large specific surface area and a π-π conjugated structure. As an ideal two-dimensional crystal material, graphene It exhibits many excellent properties, such as stable chemical properties, high mechanical strength, excellent electrical and thermal properties, etc. These unique properties of graphene make it have broad application prospects in sensing devices, composite materials, energy storage devices, electronic devices and other fields. Studies have found that its Young's modulus is 1100GPa, and its fracture strength reaches 130GPa, which is much higher than the strength of steel. It is co...
