The fibrous cellulose composite resin includes fibrous cellulose containing microfiber cellulose, a resin, and an acid-modified resin, wherein the microfiber cellulose has an average fiber width of 0.1 μm or larger, an average fiber length of 0.02 to 2.0 mm, and a percentage of fibrillation of 1.0% or higher, and hydroxyl groups substituted with carbamate groups, and the carbamate groups are ionically bonded to acidic groups of the acid-modified resin.

A method for preparing a biomass-based conductive hydrogel by 3D printing is provided. Firstly, a cellulose-based macromonomer, a rosin-based monomer, an acrylic acid monomer and an initiator are mixed in a certain proportion, stirred, and dissolved at 25-70° C. Then, diisocyanate in an amount of 5-10 wt % of a total mass of the monomers is added to the mixed solution and mixed uniformly to prepare a 3D printing photosensitive resin solution.
