    Abstract: A plasma polymerization apparatus is provided for forming a polymerization coating on an inner surface of an object. The plasma polymerization apparatus comprises a chamber, a gas supply, a monomer source, a first electrode, a second electrode, a power source, and a metal foil. The gas supply is connected to the chamber for filling the chamber with a working gas. The monomer source is connected to the chamber for providing a vaporized monomer material into the chamber. The first electrode is located at a first side of the chamber. The second electrode is located at a second side of the chamber. The power source is electrically connected to the first electrode and the second electrode for generating plasma. The metal foil is wrapped around an outer surface of the object and placed between the first electrode and the second electrode. A plasma polymerization method is also provided.

    Abstract: A method for sterilizing ambient air includes the steps of: a) installing a plasma-based smart window including an atmospheric pressure plasma device which includes first and second transparent flat patterned electrodes sandwiched between a light-transmissive substrate and a light-transmissive cover plate; and b) applying a power supply parameter of a predetermined magnitude between the first and second transparent flat patterned electrodes at ambient temperature and pressure to generate a surface plasma proximate to the light-transmissive substrate or the light-transmissive cover plate so as to inactivate microorganisms in the ambient air.
