Claim 13:
14. A method for controlling the transmission of light to a substrate, the method comprising:
disposing a porous structured polymer layer atop a substrate, the substrate having
a first surface defining at least part of an enclosed volume;
providing fluid having a refractive index that is within about 30% of the refractive index of the porous structured polymer layer in fluid communication with the porous structured polymer layer;
wetting the porous structured polymer layer with the fluid;
withdrawing the fluid from the enclosed volume to a reservoir separate from the enclosed volume; and
drying the porous structured polymer layer as the fluid is withdrawn from the enclosed volume.
