Comprising the following steps: firstly, preparing a CP40 film, and then preparing a CP40 / CT% composite film: preparing a chitosan solution with the mass concentration of 1%, adding tannic acid TA into the chitosan solution, stirring for 30 minutes in a shading manner at room temperature to form a CT coating solution, flatly laying the prepared CP40 film on a planar carrier, coating the surface of a substrate film with the CT coating solution, and putting the composite film and the carrier into a drying oven at 45 DEG C for constant-temperature drying, so as to obtain the CP40 / CT% composite film. And after the solvent of the coating layer is completely volatilized, taking out and stripping to obtain the CP40 / CT% composite film. Under the action of hydrogen bonds and electrostatic attraction, a compact network structure of an amorphous-weak crystal region is formed in the composite film, so that the interface bonding strength of the film is enhanced, and the rigidity and flexibility of the film are balanced. The physical and chemical properties and biological activity of the composite membrane are synergistically optimized, and the composite membrane has obvious degradation signs after being buried in soil for 35 days and belongs to a biodegradable material.

This invention discloses a high-energy-storage flexible wood fiberboard, its preparation method, and its applications, belonging to the field of wood functional materials. It disperses a non-isocyanate polyurethane formed by the reaction of epoxidized soybean oil cyclic carbonate and soybean protein within polyacrylamide chains. The hydrogen bonding between the polyacrylamide chains and the non-isocyanate polyurethane transfers external stress and dissipates energy, thereby improving the adhesive's toughness. Simultaneously, a conductive material is introduced into the three-dimensional network structure formed by mixing porous wood fiber materials to prepare conductive composite wood fibers. A multi-dimensional, multi-scale hierarchical directional composite assembly technology of wood fiber materials and novel conductive adhesives is employed to achieve directional charge transfer from the polymer to the wood pores, giving the flexible wood fiberboard intrinsically high energy storage characteristics. This helps solve the problem of traditional furniture's single-carrier function and promotes the high-value utilization of wood materials.
