Abstract:
An apparatus and a method for surface coating by means of grid control and plasma-initiated gas-phase polymerization. The method comprises: dividing a vacuum chamber into a discharging cavity and a processing chamber by using a metal grid mesh, the metal grid mesh being insulated from the vacuum chamber; separately feeding carrier gas and monomer steam into the discharging cavity and the processing chamber through different pipes, putting a substrate to be processed in the processing chamber, and generating in the discharging cavity plasma that continuously discharges; and applying pulse positive bias to the metal grid mesh, to release the plasma into the processing chamber to initiate monomer polymerization.

Claim (Index 3):
A method for initiated vapor polymerization surface coating by using the apparatus for initiated vapor polymerization surface coating by grid-controlled plasma according to  claim 1 , comprising the following steps:\n 1) placing the to-be-processed base material in the processing chamber; 2) flowing the carrier gas into the discharging cavity through the carrier gas pipeline, and flowing the monomer vapor into the processing chamber through the the monomer steam pipeline; meanwhile, heating the filament electrode and applying high voltage by the power supply to generate continuous glow discharge in the discharging cavity, and applying positive pulse bias generated by the pulse bias power supply on the metal mesh grid; 3) generating stable plasma by continuous discharge in the discharging cavity; applying positive pulse bias on the metal mesh grid to control and release the plasma entering the processing chamber to initiate the monomer vapor to polymerize and deposit on the surface of the to-be-processed base material to form a polymer coating, wherein a structural unit of the monomer at least includes one unsaturated carbon carbon bond, and one unsaturated carbon atom does not include a substituent group; and the performance of the formed polymer coating keeps consistent with the nature of a characteristic functional group in the monomer structure.
