Claim of US Patent No. 10,189,967

1. A structure comprising:a macroporous photonic crystal membrane including a three dimensional array of macropores, wherein a three dimensional polymer framework separates the macropores, wherein the polymer framework is made of a copolymer of two oligomers, wherein the two oligomers are ethoxylated (20) trimethylolpropane triacrylate (ETPTA 20) and polyethylene glycol (600) diacrylate (PEGDA 600), wherein when the macropores are in a collapsed state, the macroporous photonic crystal membrane is substantially transparent and wherein when the macropores are in an uncollapsed state, the macroporous photonic crystal membrane has an iridescent color.
