Abstract
In accordance with the purpose(s) of the present disclosure, as embodied and broadly described herein, embodiments of the present disclosure, in one aspect, relate to porous polymer membranes, structures including porous polymer membranes, devices including porous polymer membranes, methods of using porous polymer membranes, methods of making porous polymer membranes, and the like.
Claims15
A method of making a structure, comprising:
- disposing nanoparticles onto a surface to form an array of nanoparticles;
- introducing a prepolymer mixture to the array of nanoparticles;
- polymerizing the prepolymer mixture to form a polymer framework around the array of nanoparticles;
- and
- removing the nanoparticles to form an ordered array of voids to form a porous polymer membrane, wherein the distance between at least two pairs of adjacent voids is substantially the same, wherein the polymer framework separates the voids, wherein when the voids are in a collapsed state the porous polymer membrane is substantially clear, wherein when the voids are in a uncollapsed state the porous polymer membrane has an iridescent color, wherein upon pressure to an area of the collapsed voids, the collapsed voids renew their uncollapsed state, and wherein upon exposure to an area of the collapsed void to a solvent, the collapsed voids renew their uncollapsed state.
