    Abstract: A method for generating spontaneously aligned surface wrinkles utilizes control of local moduli-mismatch and osmotic pressure. The method includes modifying the surface of an elastomeric layer to form a superlayer that is stiffer and/or less absorbent than the elastomeric layer. The elastomeric layer is then swollen with a polymerizable monomer, which causes buckling of the superlayer. The monomer is then polymerized, dimensionally stabilizing the surface buckling. The buckled surfaces generated by the method are useful in a wide variety of end-use applications, including microlenses, microlens arrays, compound microlenses, diffraction gratings, photonic crystals, smart adhesives, mechanical strain sensors, microfluidic devices, and cell culture surfaces.

The processing method comprises a modifying step of curing an organic film by irradiating the organic film with electron beams by means of an electron-beam irradiation device in a rare gas atmosphere, and an applying step of applying a polar liquid to the modified surface of the organic film or a film forming step of forming an inorganic film on the organic film. The organic film is cured and affinity for the polar liquid or the inorganic film is imparted to the organic film.

  • Patent number: 7452609
    Abstract: The present invention provides inexpensively an article with a hard coat excellent in anti-staining property, lubricity, scratch resistance and abrasion resistance. The present invention provides a method for forming the hard coat. A hard coat agent composition comprising an active energy ray-curable compound is applied onto a surface of an article 1 to be hard-coat-treated, thereby forming a hard coat agent composition layer, a surface material layer is formed by film-forming with a surface layer material comprising an active energy ray-curable compound having anti-staining property and/or lubricating property on the surface of the hard coat agent composition layer, and active energy rays are irradiated onto the formed hard coat agent composition layer and surface material layer so as to cure the two layers simultaneously, thereby forming a hard coat layer 2 contacting the surface of the article 1 and an anti-staining surface layer 3 contacting the surface of the hard coat layer 2.

  • Patent number: 7264669
    Abstract: A gradient coating is comprised of a basecoat derived from a polysiloxane prepolymer obtained from a mixture of one to three alkoxysilane monomers and at least one diepoxide monomer, and a lubricious reactant. The basecoat is applied to a substrate and dried. The lubricious reactant is then applied and allowed to permeate into the basecoat. The basecoat and lubricious reactant are then co-cured, resulting in a gradient coating composition. In addition to providing enhanced scratch and mar resistance, the gradient coating composition is solvent resistant and provides a durable hydrophobic and oleophobic surface, which makes it useful as a corrosion protectant and as a release agent.
