▎ 摘　　要

NOVELTY - A composite electrogenesis fiber based on sodium alginate is prepared by configuring fiber coagulation bath by 2-4 wt.% sodium alginate solution, 10-20 mg/mL graphene oxide solution, 2-8 mg/mL carbon nanotube solution, 2- 4 mol/L lithium chloride solution and 5-15 wt.% calcium chloride, uniformly mixing 55-70% sodium alginate solution, 10-15% graphene oxide solution and 15-33% cellulose nanofiber, adding 5 mL carbon nanotube solution, uniformly mixing and stirring to obtain mixed solution, injecting into fiber coagulation bath through sample injector to form fiber, cleaning fiber, naturally drying, soaking with lithium chloride solution and drying. USE - The method is used for preparing composite electrogenesis fiber based on sodium alginate. ADVANTAGE - The method is simple and convenient, has short preparation period, low preparation cost, material hat can be purchased or prepared in laboratory and added chemical components that are not provided with corrosion so that fiber has good skin-friendly property, and strengthens and stabilizes generated voltage by adding graphitized carboxylated multi-wall carbon nanotube. The fiber can be woven into different shapes for application and absorb moisture in air to become moist and ionize large amount of hydrogen ions, has strong fibre plasticity and good toughness, torsion resistance and tensile resistance, improves water absorption performance in air, and moves molecules along fiber and gathers hydrogen ions to a section of fiber resulting in characteristics of voltage.
