Abstract:
Methods for making antimicrobial coating materials are described. Antimicrobial materials and antimicrobial material precursors are formed from hexahydrotriazine and/or a hemiaminal material and a non-fouling material and adhesive material may be incorporated into the antimicrobial materials and antimicrobial material precursors. The hexahydrotriazine and/or hemiaminal material may be made from a diamine and an aldehyde. Metal ions are also incorporated into the antimicrobial material precursors to form an antimicrobial material.
Abstract:
The invention relates to a method for functionalising a surface of a solid substrate with at least one acrylic acid polymer layer, said method comprising the steps of: i) placing said surface in contact with a solution consisting of at least one acrylic acid homopolymer, a solvent and, optionally, metal salts; ii) removing the solvent from the solution in contact with said surface; and iii) binding the polymer to said surface by thermal treatment.
Abstract:
A method of preparing a conductive metallic layer or pattern comprising the steps of: - applying a metallic nanoparticle dispersion on a support to obtain a metallic layer or pattern, - contacting the metallic layer or pattern with a solution containing an acid or an acid precursor capable of releasing the acid during curing of the metallic layer or pattern. It has been observed that by contacting the metallic layer or pattern with a solution containing an acid or an acid precursor capable of releasing the acid, higher conductivities at moderate curing conditions are obtained.
Abstract:
A method for producing a porous polymer structure involves (i) forming a polymer; (ii) subsequently contacting the polymer with a nonsolvent and inducing the formation of an emulsion in which the nonsolvent is present as the dispersed phase and the polymer as the continuous phase; and (iii) removing at least some of the nonsolvent so as to leave pores within the polymer, wherein the polymer is formed by exciting one or more molecules in an exciting medium, in particular by pulsed plasma deposition. Emulsion formation in step (ii) may be induced by or in the presence of an emulsion stabilising agent. Also provided is a porous polymer structure produced using the method, and a polymer which is impregnated with an emulsion stabilising agent, for use in the emulsion formation step of the method.

One aspect of the invention provides a method for fabrication of a membrane on a surface. The method includes: providing a surface interfacing two environments, wherein one of the environments is a liquid; providing a flow-recirculating fluidic device having channel exits in the liquid environment in proximity of the surface; and delivering locally one or more processing solutions. The one or more processing sources including one or more membrane sources adapated and configured to form a membrane on the surface.
Abstract:
An article with different surface properties on opposing sides is provided including a sheet having a first side and a second side, wherein the first side displays low adhesion properties, said first side comprising a roughened, porous or structured surface and a wetting liquid disposed upon the surface to form a stable liquid film; and wherein the second side displays a second property dissimilar from that of the first side. The article can be adhered to a variety of objects to impart anti-fouling properties.
Abstract:
The invention provides a method for chemically modifying a surface of a substrate, preferably a silicon substrate, comprising the steps of providing a substrate having at least a portion of a surface thereof coated with an organic coating composition comprising unsaturated moieties forming a surface coating, and introducing a vapour phase reactive intermediate species based on a Group 14 or Group 15 element from the Periodic Table of Elements to the substrate whereupon said reactive intermediate species is able to react with a number of the unsaturated moieties in the coating composition thereby chemically modifying the surface coating. Also disclosed is a surface-modified substrate obtained or obtainable by the method, and uses thereof in the fabrication of MEMS and IC devices.
Abstract:
An architectural construct is a synthetic material that includes a matrix characterization of different crystals engineered to exhibit certain properties. An architectural construct can be fabricated by a process involving layer deposition, formation, exfoliation and spacing. In one aspect, purified methane can be dehydrogenated onto a substrate by applying heat through the substrate. Deposited carbon can form a plurality of layers of a matrix characterization of crystallized carbon through self-organization. The layers can be exfoliated and spaced to configure parallel orientation at a desired spacing and thickness using selected precursors and applying heat, pressure, or both. The desired architectural construct can further be stabilized and doped to exhibit desired properties.
