The formation of microporous surfaces through polymer induced phase separation in a photopolymer solvent mixture using photopolymerization via light self-focusing and self-trapping. The self-trapping of light sets fixed regions of brightness and darkness, sustained by the polymerization of light, and then wave guiding within the substrate. Phase separation occurs with the solvent phase separating in the regions of darkness and crosslinking in the regions of brightness. Upon removal of the solvent, precise and uniformly dispersed pores are created in the surface. The pore size and spacing may be tuned by adjusting the weight fraction of the photopolymer solvent mixture as well as through changes in the mask pattern. 1. A microporous structure , comprising a polymerized monomer having a surface defining a series of pores that have a diameter ranging from 10 to 40 micrometers and that are spaced apart from each other by a distance ranging from 50 to 100 micrometers.2. The structure of claim 1 , wherein the microporous structure has a thickness between 100 and 400 micrometers.3. The structure of claim 1 , wherein the monomer comprises trimethylolpropane triacrylate (TMPTA).4. The structure of claim 1 , wherein the surface is coated with a plurality of nanoparticles.5. The structure of claim 4 , wherein the nanoparticles comprise polytetrafluoroethylene (PTFE).6. The structure of claim 5 , wherein the coated surface is characterized by a static water contact angle at or above 150°. The present application is a divisional of U.S. application Ser. No. 16/164,910, filed on Oct. 19, 2018, which claims priority to U.S. Provisional App. No. 62/579,964, filed on Nov. 1, 2017.The present invention relates to microporous surfaces and, more particularly, to the combination of photopolymerization induced phase separation and light self-trapping in photopolymer-solvent mixtures to control the formation of pores.Living systems abound with surface anatomies possessing inherent porous, ...
