摘要： Textured and porous organic polymeric films can be obtained by subjecting organic polymeric films that are swellable in carbon dioxide, to supercritical carbon dioxide while such films are under an atmospheric pressure of at least 73 bar and an applied physical force of at least 0.05 Newtons. The textured and porous organic polymeric films have surface wrinkles having an average peak to valley height of at least 1 μm and up to and including 3,000 μm, and a porosity of at least 10%.

摘要： A non-aqueous silver precursor composition contains at least 1 weight % of one or more (a) polymers that are certain cellulosic polymers; (b) reducible silver ions; and (c) an organic solvent medium consisting of: (i) a hydroxylic organic solvent having an α-hydrogen atom and a boiling point at atmospheric pressure of 100-500° C., and, optionally, (ii) a nitrile-containing aprotic solvent or a carbonate-containing aprotic solvent different from the (i) organic solvent, each having a boiling point at atmospheric pressure of 100-500° C. The (b) reducible silver ions are present in an amount of 0.1-400 weight %, based on the total weight of the one or more (a) polymers. This composition can be used to form silver nanoparticles under silver ion reducing conditions and then applied to various substrates to provide silver nanoparticle patterns.
