Composite material comprising a fabric and amphoteric polyelectrolytes hydrogel is provided. In composite materials, amphoteric polyelectrolytes hydrogel is a polymer hydrogel having randomly dispersed cationic and anionic repeating groups, at least some of the fabric are coated with amphoteric polyelectrolytes hydrogel. The method for manufacturing a composite material, the step (a) ~ (c) :( a) to prepare an amphoteric polyelectrolyte monomer mixture for the hydrogel produced; (b) dipping the fabric into the monomer mixture solution; and (c) polymerizing the monomers in the monomer mixture solution and obtaining a precursor of a composite material.
