Diamond and boron nitride particles coated with a polymerized dianhydride
Abstract
Abstract A THIN, CONTINUOUS FILM IS FORMED ON A SUBSTRATE BY ULTRAVIOLET SURFACE PHOTOPOLYMERIZATION OF A MATERIAL IN THE GASEOUS PHASE. THE MATERIAL IS SELECTED FROM VARIOUS ANHYDRIDES AND DIANHYDRIDES. SUCH FILMS, WHICH CAN BE SELECTIVELY FORMED AS ELECTRICALLY INSULATING OR ELECTRICALLY CONDUCTIVE, ARE USEFUL AS COATINGS ON METALIC AND NONMETALLIC SUBSTRATES, AND FOR CORROSION PROTECTION. THE ELECTRICALLY INSULATING FILMS ARE USEFUL FURTHER AS CAPACITOR DIELECTRICS, CRYOGENIC DEVICE INSULATION, INSULATION FOR MICROELECTRIC DEVICES, AND PRIMER OR INSULATION ON ELECTRI- CALLY CONDUCTIVE WIRE, WHILE THE ELECTRICALLY CONDUCTIVE FILMS CAN ALSO BE EMPLOYED AS CONDUCTIVE LAYERS IN MICROELECTRIC DEVICES.
