Abstract

The invention relates to a micro contact pattern printing method with hydrogel as template and colloid and crystal as ink, comprising the steps that: diluting monodisperse silicon dioxide, or polystyrene, or polymethyl methacrylate microspheres with deionized water; evenly diluting and mixing the mixture of acrylamide and methylene bisacrylamide with a rate of mass to volume of 10% to the rate of3% to 6% while adding an initiator azobisisobutyronitrile; obtaining hydrogel through irradiation and polymerization for 40 minutes by a high-voltage mercury lamp under four DEG C; peeling the hydrogel off a die, sufficiently washing the hydrogel and storing the hydrogel in pure water of four DEG C; ; immersing the prepared template into colloid and crystal solution, lifting and pulling the templateby a lifting-pulling machine, facilitating the formation of self-assembled colloid and crystal foil and waiting for the foil dried under ambient temperature, and softly making a hydrogel template with patterns formed in the second step contact with a substrate of hydrophobic material of the coating layer with colloid and crystal, removing the template, and an orderly colloid and crystal being transferred to the surface of the substrate.
