A porous film includes at least one porous polyimide film that includes a polyimide resin, an organic amine compound and a resin other than a polyimide resin, and that does not include a polar aprotic solvent, wherein a content of the organic amine compound is 0.001% by weight or higher with respect to a total weight of the porous polyimide film.

Provided are a low-reflective coating layer, a porous layer, a method of fabricating the porous layer, and an optical member including the porous layer. According to an embodiment, a low-reflective coating layer comprising a porous film having hollow sphere structures or bowl-like structures is provided. Each hollow sphere structure or bowl-like structure may have cavity formed therein. The hollow sphere structures or the bowl-like structures may be formed from spherical micelles, and each spherical micelle may be formed by self-assembling a supramolecular complex of a first compound block and a second compound block. In addition, the first compound block may constitute a backbone of the supramolecular chemical compound and the second compound block may constitute a side chain of the supramolecular. The second compound block may be non-covalent bonded to the first compound block.

A biocompatible controlled release form of complexed iodine is achieved by a complexation of polyvinyl alcohol based foam and characterized by a residual starch component to optimize iodine release profiles. The resulting iodine complexed polyvinyl alcohol foam may be utilized locally as an antimicrobial agent that releases controlled amounts of iodine sufficient to kill microbes for extended durations without excessive bulk and rigidity.
