Latest Patents

Yang's patent, titled "Vapor deposition of parylene-F using 1,4-bis (trifluoromethyl) benzene," describes a method for creating a PA-F polymer film. This process involves a mixture of 1,4-bis (trifluoromethyl) benzene (TFB) and a halogen initiator, which is introduced into a low-pressure reactor containing a metal catalyst. The reactor operates at elevated temperatures to facilitate a chemical reaction that generates a reactive monomer on the catalyst's surface. This monomer is then condensed onto a substrate that is cooled to a temperature conducive to polymerization, resulting in the formation of the PA-F polymer film. The halogen initiator's proportion typically ranges from 0.25 to 50% by volume relative to the TFB/halogen initiator mixture, with the reactor functioning at temperatures between 200°C to 700°C and pressures below one torr. The substrate's surface is maintained at temperatures from -30°C to room temperature, with dibromotetrafluoro-p-xylene (DBX) being the preferred halogen initiator, typically used at a concentration of about 1 to 5%.
