Fabrication of opal hydrogel composite for humidity sensing

By diposition of monodisperse polystyrene latex with average size of ۲۲۰ nm on a glass surface, anopal was fabricated as SEM images verify.Then, acrylamide monomer and crosslinker in aqouessolution injected into the space between PS particles and polymerized. In this stage opal hydrogelcomposite (OHC) is fabricated and can be used as humidity sensor. This sensor can be usedquantitically or qualifically.
