Abstract: A polysiloxane film comprises Si—O bonds and has a thickness of 0.3 to 1.5 microns. Adjacent electrodes coated with the polysiloxane film have a leakage current of at most 0.01 mA at 10 V after contact with water. An electrode coated with the polysiloxane film has a contact resistance of at least 0.01 ohms at 1.0 mm of pogo pin compression under a 1.0 N load. The polysiloxane film provides IPx7 protection from ingress of water.

Abstract: A method of forming a polysiloxane film on a substrate comprises polymerizing a siloxane monomer in a reaction chamber containing the substrate. The polymerization is catalyzed by a 30-60 W radio frequency plasma, the pressure in the reaction chamber during the polymerization is 100-400 mTorr, the residence time of the siloxane monomer in the reaction chamber is 5-120 minutes, the siloxane monomer is heated to 30-200° C. before entering the reaction chamber, and the polymerization is carried out at a temperature of 30-100° C.

Abstract: A dispersion comprised of at least 49 wt % of additive particles, a polymerizable monomer, a dispersant and a solvent. Upon polymerization the dispersion forms a hard coat with a haze of at most 0.5% and a transmission of at least 90%. A hard coat comprises at least 49 wt % of additive particles dispersed in a polymer. A method of making a hard coat comprises forming a dispersion, applying the dispersion to one side of a substrate, and polymerizing the dispersion. The hard coat has a haze of at most 0.5% and a transmission of at least 90%.
