Description
Technical Field
The invention relates to the technical field of two-dimensional sheet material modification, in particular to a polymer surfactant for simultaneously stripping and vinylating a two-dimensional sheet material, preparation and application thereof, and application of the surfactant modified two-dimensional sheet material.
Background
The molybdenum disulfide nanosheet, the boron nitride nanosheet, the graphene nanosheet and the like with the two-dimensional lamellar structure have excellent mechanical properties, photothermal effect, heat conducting property, electric conductivity and the like, and are ideal fillers for preparing high-mechanical-property functional nano composite materials at present. The mainstream methods for stripping the two-dimensional lamellar material at present comprise an intercalation method, a mechanical ball milling method, a liquid phase ultrasonic method and an electrochemical method. The sheet material obtained by the liquid-phase ultrasonic stripping method has uniform size, is easy to realize surface functionalization, and is suitable for stripping the two-dimensional sheet material of the reinforced polymer. For example, researchers use homemade polymer ionic liquid as a surfactant to assist in efficient stripping of selenium disulfide in an aqueous medium and simultaneously achieve non-covalent modification of the selenium disulfide surface, but the preparation process of the polymer ionic liquid in the foregoing method is complicated and tedious, and is difficult to produce on a large scale. For another example, researchers have directly adopted a commercial product Pluronic as a surfactant to achieve exfoliation and functionalization of molybdenum disulfide nanosheets. The interface in the molybdenum disulfide nanosheet composite obtained by the above method is formed by physical entanglement. Most of the two-dimensional lamellar nanosheet composite interfacial effects are also formed by physical effects, such as electrostatic effects, hydrogen bonding effects, physical adsorption effects and the like. The interface interaction formed by physical action is weak, energy loss is caused at the interface, and the further improvement of the performance of the two-dimensional lamella nanosheet composite material is limited. At present, most of the existing researches concern the peeling effect of the two-dimensional sheet material and the dispersion degree of the two-dimensional sheet material in the matrix, and the research on the interface design between the two-dimensional sheet material and the matrix is less.

Detailed Description
As mentioned above, the method for peeling and functionalizing the two-dimensional layered material needs to be improved continuously to meet the requirement of preparing a functional two-dimensional nanosheet composite material with high mechanical properties. The inventor of the present invention has made extensive research and practice to provide a vinyl-functionalized polymer surfactant and a technical solution for simultaneously peeling and functionalizing a two-dimensional sheet material. The preparation and technical scheme of the surfactant will be explained in detail as follows.
The surfactant is prepared by reacting polyethyleneimine and allyl glycidyl ether in a molar ratio of 1: 0.5-2 at 40-80 ℃ for 4-10 h. Wherein the number average molecular weight Mn of the polyethyleneimine is 70000, and the structure is a hyperbranched structure.
The surfactant is prepared by reacting amino of polyethyleneimine with epoxy of allyl glycidyl ether, is in a hyperbranched structure, and has a hydrophobic allyl ether chain at the tail end. This portion of the hydrophobic segment does not affect the readily water-soluble nature of the surfactant molecule.
The water solution of the compound is electropositive due to the existence of primary amine, secondary amine and tertiary amine groups in the molecule and the ammonium ions can be formed with water.
As can be seen from FIG. 1, the peaks at 2 to 3ppm are ascribed to the proton peak of methylene, the nuclear magnetic peaks at 2.4 to 2.9ppm are ascribed to the proton peak of methylene, and the nuclear magnetic peaks at 5.8 to 5.9ppm are ascribed to the proton peak b of allyl, indicating the presence of vinyl in the surfactant molecule. The average substitution degree of the amino group in the surfactant was 0.68, which means that 0.68 mol of vinyl group was contained per 1 mol of the surfactant molecule, as calculated from the proton peak area.
The surfactant is applied to assisting efficient stripping and functional modification of a two-dimensional sheet material under the action of ultrasound, and the ultrasound conditions are as follows: ultrasonic treatment is carried out for 8-16 h under 200-300W of power. The two-dimensional lamellar material is molybdenum disulfide, boron nitride or graphene, and molybdenum disulfide is preferred. The mechanism is that the inorganic two-dimensional sheet material is hydrophobic and is electronegative in water, and under the ultrasonic condition, stripping and functionalization are successfully realized through the electrostatic interaction and the hydrophobic interaction between the surfactant and the two-dimensional sheet material, so that the two-dimensional sheet material with a large amount of vinyl on the surface and the physical adsorption inside is formed.
As can be seen from the figures 2a and 2b, the transverse size of the molybdenum disulfide nanosheet obtained by stripping is 100-200 nm, and the thickness is 2-6 nm, which shows that the molybdenum disulfide is successfully stripped into nanosheets with uniform sizes under the assistance of the surfactant through the ultrasonic effect.
As can be seen from fig. 3a and 3b, the vinyl functionalized polymer surfactant is indeed present on the surface of the molybdenum disulfide nanosheet, indicating that under ultrasonic conditions, the surfactant molecules are successfully adsorbed on the nanosheet surface through electrostatic interaction and hydrophobic interaction.
As can be seen from fig. 4 and 5, the vinylated molybdenum disulfide nanosheets have significantly increased hydrophilicity and are capable of forming a stable dispersion in an aqueous solution.
The prepared vinylation two-dimensional lamellar material can be used as a cross-linking agent of a synthetic polymer. The synthetic polymer is obtained by free radical polymerization of vinyl monomers and can react with vinyl in the vinyl two-dimensional lamellar material in the polymerization reaction process, so that a chemical cross-linking interface effect is formed, and meanwhile, a physical adsorption effect exists in the vinyl two-dimensional lamellar material, so that a physical cross-linking interface interaction is formed, an interface with coexistence of chemical cross-linking and physical cross-linking is formed, and the preparation of the functional two-dimensional nanosheet composite material with high mechanical properties is facilitated.
The vinyl monomer comprises any one or the combination of more than two of acrylamide, acrylic acid and N-isopropyl acrylamide.
The present invention is described in detail below by way of examples, it should be noted that the examples are only for the purpose of further illustration, and are not to be construed as limiting the scope of the present invention, and that those skilled in the art can make insubstantial modifications and adaptations of the present invention based on the above disclosure.
