    Abstract: A double-inverse opal photonic crystal resin film is formed by embedding nanospheres in pores of polyacrylate inverse opal framework material and then filling the pores of the double-inverse opal photonic crystal resin film with an ethanol solution with hydrophilic acrylamide dissolved therein followed by photopolymerization to form a polyacrylamide network, so as to obtain the double-inverse opal photonic crystal resin film using water as ink. A mass fraction of hydrophilic acrylamide in the ethanol solution is 2 to 8 wt.%. The resin film can induce water to penetrate into the pores of the double-inverse opal photonic crystal resin film, making the nanospheres in the pores of the inverse opal framework distribute from random to order under the action of buoyancy force, thereby eliminating scattering interference and producing brilliant structural colors by regulating refractive index contrast.
