▎ 摘　　要

NOVELTY - High-toughness conductive and anti-freezing carbon nanotube organic hydrogel, is claimed. The carbon nanotube organic hydrogel is prepared by (i) adding polyvinyl alcohol (PVA), propionamide (AAm), vinyl acetate (VAc), N-methylene bisacrylamide (MBA), hydroxylated multi-walled carbon nanotubes; (ii) adding PVA to the dimethyl sulfoxide/water mixed solvent, fully dissolving at 110 degrees C, cooling to room temperature, slowly adding the weighed HO-MWCNT, and then include the configured AAm and The mixed solution of VAc, add APS and stirring uniformly, then ultrasonically degassing, pouring the liquid into the mold, reacting at 60 degrees C for 6 hours, cooling to room temperature, freezing at -20 degrees C for 24 hours, and unfreezing at room temperature. USE - Used as high-toughness conductive and anti-freezing carbon nanotube organic hydrogel. ADVANTAGE - The organic hydrogel: can exhibits excellent tensile strength, break point elongation and conductivity, respectively 561 KPa, 2134% and 0.00312 S/cm, improves the frost resistance and has freezing point at 60 degrees C.
