When the corrosion-resistant degradable antibacterial hemp fiber fishing net is prepared, firstly, dicarbonyl butyryl chloride di (3, 4-dimethyronitrile phenoxy) silane and activated nano iron oxide particles are mixed to prepare a nano iron oxide mixed solution, so that a large amount of nano iron oxide is prevented from being agglomerated in hemp fibers; the preparation method comprises the following steps: preparing hemp fibers, carrying out supercritical swelling on the hemp fibers by using ethylenediamine to form antibacterial Schiff base, putting the antibacterial Schiff base into a nano iron oxide mixed solution, and carrying out ultrasonic coupling electric heating treatment and warp knitting to form a polypyrrole and metal phthalocyanine film, thereby preparing the corrosion-resistant degradable antibacterial hemp fiber fishing net. The corrosion-resistant degradable antibacterial hemp fiber fishing net prepared by the invention has good antibacterial performance, tensile strength and corrosion resistance.
