Abstract
nanoparticles in different particle sizes and PAH multilayers were fabricated. The obtained polyelectrolytes-nanoparticle multilayers were fluorinated by a fluorinating agent. Such polyelectrolytes-nanoparticle multilayered coating renders obvious micro-nano composite structure, showing excellent superhydrophilicity, whereas such coating modified eyeglasses keeps excellent light transparency. The results of antifogging and defogging test also proved that the eyeglass modified with this coating had good antifogging and defogging performance. Therefore, such polyelectrolytes-nanoparticle multilayered coating with excellent superhydrophobic and transparent properties might provide a feasible approach for the practical antifogging application of optical lenses.
