  • Patent number: 10449473
    Abstract: The invention provides a coating which exhibits fast oleophobic-hydrophilic switching behaviour with, for example, equilibration of high oil contact angle (hexadecane=80°) and low water contact angle (<10°) values which occur within 10 s of droplet impact. These optically transparent surfaces display excellent anti-fogging and self-cleaning properties. The magnitude of oleophobic-hydrophilic switching can be further enhanced by the incorporation of surface roughness and in one embodiment the coating is applied to a surface in the form of a mesh in order to form an effective filter.

  • Patent number: 8597736
    Abstract: A method for producing polymer coatings by surface initiated polymerization from a plasma deposited coating is provided. The modification of surfaces by polymer attachment is a versatile and efficient means of controlling interfacial properties, such as surface energy (i.e. wetting behavior), permeability, bio-activity, and chemical reactivity. The present invention provides a method whereby a plasma deposited coating is applied to a substrate and the polymer coating formed by surface initiated polymerization is formed on the coating rather than the substrate itself. This means that the growth of the polymer using the grafting from procedure can be performed efficiently and independently of the substrate from.

  • Publication number: 20100055413
    Abstract: The invention relates to the provision of an article and a method of forming an article with a surface which can have at least one sub-layer and a top layer of material. At least one part of the top layer is selectively removed to expose at least one sub-layer and/or the surface of the substrate and allow the functionality of the sub-layer and/or surface to be utilised in the area(s) where it is exposed. The top layer, where it remains, acts as a barrier to the sub-layer and/or surface being exposed to the surrounding environment. Typically parts of the top layer are removed in a patterned manner to provide a series of predefined areas at which the sub-layer or sub-layers are selectively exposed.
