  • METHOD FOR DEPOSITING A BIOCIDAL COATING ON A SUBSTRATE
    Publication number: 20130209811
    Abstract: A method produces a biocidal coating on a substrate, by a flame assisted chemical vapour deposition and a plasma assisted chemical vapour deposition step. In a first step, a biocidal material is deposited onto the substrate, possibly in combination with a first coating forming material. The second step provides a coating forming material onto the first layer, possibly in combination with a second biocidal material. The first step can be a flame assisted CVD step and the second step a plasma assisted CVD step or vice versa.

  • METHODS OF NUCLEATION CONTROL IN FILM DEPOSITION
    Publication number: 20110086235
    Abstract: Disclosed herein are methods to achieve a significant degree of nucleation control with a chemical vapor deposition based coating approach, by controlling the chemistry of a specifically chosen under layer on a substrate such as glass and then treating this under layer on at least its surface to a specified degree to achieve targeted nucleation control in the second layer film, which is at least partially crystalline.

  • Titania coatings by cvd at atmospheric pressure
    Publication number: 20060141290
    Abstract: A method for deposition of titania, and titania-containing, thin films by CVD, using an atmospheric pressure glow discharge plasma as a major source of reaction, which leads to film properties, and film growth rates, normally only achievable (by atmospheric pressure CVD) with significantly higher substrate temperatures.
