  • Patent number: 9566609
    Abstract: Methods for replicating a nanopillared surface include applying a nanopillar-forming material to a surface of a replica substrate to form a precursor layer on the replica-substrate surface. A template surface of a nanomask may be contacted to the precursor layer. The nanomask may include a self-assembled polymer layer on a nanomask-substrate surface, the template surface being defined in the self-assembled polymer layer. The self-assembled polymer layer may have nano-sized pores with openings at the template surface. The precursor layer may be cured while the template surface remains in contact with the precursor layer. The nanomask is removed to expose a nanopillared surface having a plurality of nanopillars on the replica-substrate surface. The nanopillars on the replica-substrate surface may correspond to the pores in the template surface. Nanopillared surfaces may be replicated on one side of the replica substrate or on two opposing sides of the replica substrate.

  • Patent number: 9434641
    Abstract: A method for protecting a sheet surface by forming a discontinuous layer of a long-chain organic material having a main carbon chain comprising at least 12 carbon atoms and a hydrophilic group at one end of the main chain on the sheet surface. The protective layer is easy to remove using standard cleaning method, while providing satisfactory surface protection against particle contamination and scratches, at a very low coating thickness. The invention is particularly useful for protecting glass sheet surfaces during glass sheet finishing such as edge grinding and polishing. The invention is especially useful for the finishing and packaging of LCD glass substrates.

  • Publication number: 20110053270
    Abstract: A method for forming a pattern-coated substrate includes disposing a composition comprising a polysaccharide-based polymer on a substrate to generate a coated substrate. The polysaccharide-based polymer composition is substantially free of cross-linking monomers. The method further includes exposing a portion of the coated substrate to a first dose of UV radiation to induce crosslinking of the polysaccharide-based polymer, wherein a portion of the substrate is shielded from the ionizing radiation. The UV exposed coated substrate may be washed or hydrated to remove uncross-linked polysaccharide-based polymer.
