✦ Synopsis

In lithographic techniques for forming nanostructures in surface and polymer thin films, the selectivity of the solvent becomes increasingly important as the target dimensions decrease. Polymer‐based developers. The Figure shows the SC CO~2~–developed image of a copolymer of pentafluoroproyl methacrylate and tert‐butyl methacrylate.magnified image

Silicon-containing organic/inorganic composites were prepared from poly(styrene-co-allyl alcohol) (PSAA) and soluble starch (SS) by infusing SiCl 4 into them using supercritical carbon dioxide (SC CO 2 ) as the carrier medium. The resulting hybrid materials were studied by Fourier transform infrared
