Multifunctional metallized wood material as well as preparation method and application thereof

The invention belongs to the field of natural polymer modified materials, and particularly relates to a method for preparing a multifunctional metallized wood material from wood. The preparation method comprises the following steps: firstly, subjecting wood to alkali treatment and bleaching, and removing hemicellulose and lignin to obtain porous wood rich in cellulose and excellent in elasticity;then subjecting the porous wood to simple oxidation reaction to obtain oxidized porous wood; carrying out glutaraldehyde cross-linking reaction on the oxidized porous wood and a functional polymer polyethyleneimine to obtain polymer wood with chelated heavy metal ions; and finally, subjecting the polymer wood to metal electroless deposition to obtain the metallized wood material with a porous andstable metal layer and good compression performance. The metallized wood material prepared by the method has excellent catalysis and circulation catalysis effects, good conductivity and outstanding antibacterial property, is u
