Abstract:
1. A process comprising: applying a solution comprising a first polyelectrolyte that comprises an ionized functional group to a transparent support, followed by washing and drying the support, thereby obtaining a first polyelectrolyte deposit on the support; applying a solution comprising polymer microparticles that comprise an ionized group with a charge opposed to a charge of the first polyelectrolyte deposit to the first polyelectrolyte deposit, followed by washing the first polyelectrolyte deposit, thereby obtaining a deposit of the polymer microparticles on the first polyelectrolyte deposit; covering the deposit of the polymer microparticles with a solution comprising a second polyelectrolyte that comprises an ionized functional group with a charge opposed to the charge of the polymer microparticles, followed by washing and drying the deposit of the polymer microparticles, thereby obtaining a second polyelectrolyte deposit; applying a solution comprising ionized inorganic nanoparticles having a surface charge opposed to the charge of the second polyelectrolyte to the second polyelectrolyte deposit, followed by washing the second polyelectrolyte deposit, thereby obtaining a first layer of ionized inorganic nanoparticles; and removing the deposit of the polymer microparticles and the first and second polyelectrolyte deposits, thereby obtaining a deposit of inorganic nanoparticles on the transparent support, wherein the deposit of inorganic nanoparticles comprises micro gaps.
