Abstract: Disclosed methods include formulating azobenzene-based polymer networks to induce a modulus change in a highly crosslinked polymer, in vivo, with no external heat requirement and using a benign light as the source of stimuli. A modulus change can be achieved via a coating on the substrate and within the bulk of the substrate via photoexposure. The azobenzene-based polymer network can be formed as a coating or in the bulk of a material from either a glassy composition comprising methyl methacrylate (MMA), poly (methyl methacrylate) (PMMA), and triethylene glycol dimethacrylate (TEGDMA) or a soft material comprising of long-chain difunctional acrylates. The disclosed technology also includes methods of biofilm disruption and removal from the surface of a substrate, and includes methods of inhibiting biofilm growth and cell attachment to a substrate.

The thermoplastic resin composition can have good properties in terms of weather resistance, impact resistance, appearance, and/or antibacterial properties (activity).
Abstract: Methods to pattern substrates with dense periodic nanostructures that combine top-down lithographic tools and self-assembling block copolymer materials are provided. According to various embodiments, the methods involve chemically patterning a substrate, depositing a block copolymer film on the chemically patterned imaging layer, and allowing the block copolymer to self-assemble in the presence of the chemically patterned substrate, thereby producing a pattern in the block copolymer film that is improved over the substrate pattern in terms feature size, shape, and uniformity, as well as regular spacing between arrays of features and between the features within each array compared to the substrate pattern. In certain embodiments, the density and total number of pattern features in the block copolymer film is also increased. High density and quality nanoimprint templates and other nanopatterned structures are also provided.

Abstract: A method of forming at least one lithography feature, the method including: providing at least one lithography recess on a substrate, the or each lithography recess having at least one side-wall and a base, with the at least one side-wall having a width between portions thereof; providing a self-assemblable block copolymer having first and second blocks in the or each lithography recess; causing the self-assemblable block copolymer to self-assemble into an ordered layer within the or each lithography recess, the ordered layer including at least a first domain of first blocks and a second domain of second blocks; causing the self-assemblable block copolymer to cross-link in a directional manner; and selectively removing the first domain to form lithography features of the second domain within the or each lithography recess.
