11. A method to apply a coating of Parylene and boron nitride to an object, comprising the steps of:
-
A. vaporizing Parylene dimers by heating them to about 150 to about 200 degrees C. to form gaseous Parylene dimers; B. cleaving gaseous Parylene dimers to gaseous Parylene monomers by heating gaseous Parylene dimers to about 650 to about 700 degrees C.; C. injecting boron nitride into the gaseous Parylene monomers of Step B; and D. contacting the object to be coated with Parylene with the gaseous Parylene monomers and boron nitride of Step C for sufficient time to deposit coat of Parylene and boron nitride of a final thickness. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
