1. A method for producing a conductive glass fiber mesh with laser induced coating graphene, comprising:
(I) preparing a glass fiber paper coated with a carbon-containing precursor material, wherein the glass fiber paper coated with the carbon-containing precursor material is prepared by a wet papermaking process comprising:
(i) preparing a dispersion of the carbon-containing precursor material;
(ii) preparing a mixed pulp of the carbon-containing precursor material and glass fibers; and
(iii) pressing the mixed pulp into the glass fiber paper coated with the carbon-containing precursor material on upper and lower surfaces thereof;
(II) subjecting the glass fiber paper coated with the carbon-containing precursor material to laser irradiation to reduce the carbon-containing precursor material into the laser induced coating graphene, obtaining a glass fiber paper coated with the laser induced coating graphene; and
(III) folding the glass fiber paper coated with the laser induced coating graphene to obtain the conductive glass fiber mesh with laser induced coating graphene.
