Disclosed are a leaf-inspired hydrogel composite and a preparation method thereof, belonging to the field of biomimetic composites. The disclosure includes the following steps: preparing a green fabric by formulating a printing paste with a colorant and printing it onto a fabric, thereby obtaining the green fabric capable of simulating the green peak and red edge spectral features of plant leaves, mimicking the palisade tissue and skeletal structure of leaves using the green fabric; formulating a hydrogel prepolymer solution using PVA as a matrix, combined with a highly hygroscopic monomer, a crosslinking agent, and an initiator; and finally pouring the solution into a mold containing the green fabric for polymerizing, enabling in situ hydrogel formation on the fabric surface and within its pores to yield the leaf-inspired hydrogel composite. The composite eliminates reliance on hygroscopic salts while ensuring stable moisture absorption and simulation performance, as well as excellent durability.
