| 20090286435 | Method for Producing, and a Substrate with, a Surface with Specific Characteristics - The invention relates to a method of rendering the surface of a substrate, or at least part of the substrate, to have increased protein resistance. This is achieved by applying an n-substituted glyconic derivative onto the surface of the substrate, or areas or domains of the substrate surface, to allow the pattern resistance to be changed in those areas where the material is applied. In one embodiment the deposition is performed in or in conjunction with a plasma. | 11-19-2009 |
| 20090311555 | Methof for Producing a Thiol Functionalised Coating - A method is provided for applying a reactive thiol containing coating to a substrate. The method includes subjecting the substrate to a plasma discharge in the presence of a compound of formula (I) or formula (Ia): where X is an optionally substituted straight or branched alkylene chain(s) or aryl group(s); R | 12-17-2009 |

| 20100072642 | Method of Coating a Contact Lens - A method of coating a contact lens comprising the steps of forming an initiator layer on the surface of the contact lens by plasma deposition of at least one initiator monomer and polymerising a propagation monomer onto the initiator layer to form a coating layer of a polymeric material on the contact lens and a method of coating a medical device comprising the steps of forming an initiator polymer layer on at least a part of the medical device by plasma deposition of at least one initiator monomer and polymerising at least one zwitterionic monomer onto the initiator layer to form a coating layer of a polymeric material on the medical device. | 03-25-2010 |
| 20100330347 | METHOD AND APPARATUS FOR THE FORMATION OF HYDROPHOBIC SURFACES - The invention relates to the application of a coating to a substrate in which the coating includes a polymer material and the coating is selectively fluorinated and/or cured to improve the liquid repellance of the same. The invention also provides for the selective fluorination and/or curing of selected areas of the coating thus, when completed, providing a coating which has regions of improved liquid repellance with respect to the remaining regions and which remaining regions may be utilized as liquid collection areas. | 12-30-2010 |

| 20090318609 | Method for producing a nitrogen functionalised surface - A method is provided for applying a coating containing reactive nitrogen functionality contained within an aromatic heterocyclic structure to a substrate. The method includes subjecting said substrate to a plasma discharge of a monomer possessing said heterocyclic nitrogen functionality. | 12-24-2009 |
| 20100009095 | Method and Apparatus for Producing a Coating on a Substrate - The invention is directed toward the use of an atomizer to inject a coating material typically in the form of a liquid/solid particulate slurry into a sub-atmospheric pressure plasma to generate a high flux of excited coating forming material that permits the rapid deposition of a composite coating onto a substrate. The use of plasma discharges at reduced pressures results in the more efficient consumption of process precursors and gases, a reduced risk of explosion compared to atmospheric pressure processes and facilitates the removal of volatile components from the deposited composite coatings prior to their use. | 01-14-2010 |
| 20100055413 | ARTICLE, AND A METHOD FOR CREATING THE ARTICLE, WITH A CHEMICALLY PATTERNED SURFACE - 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. | 03-04-2010 |
| 20100240827 | Method for Producing a Grafted Polymer Coating and Substrates Formed in Accordance With the Method - 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. | 09-23-2010 |
