Patent ID: 7235302

Claim:
An article comprising: a first subsrate having a surface; and a second substrate having a surface, wherein the surface of the first substrate contacts the surface of the second substrate, and wherein each of the first and second substrates in independently comprise a matrix material selected from a metal, a glass, an organic-inorganic composite, a fluropolymer, and a non-fluoropolymer polymer with the proviso that at least one of the first substrate and the second substrate is a fluoropolymer that forms a mixture with a bonding composition, wherein the bonding compositton includes a light-absorbing compound that absorbs light between 200 nm and 400 nm, and an electron donor that is distinct from the light absorbing compound, such that when the bonding composition is exposed to actinic radiation of a wavelength that is absorbed by the light-absorbing compound, free radicals are generated at the interface of the first and second substrates thereby enhancing the bonding of the first substrate to the second substrate, further wherein the electron donor is an alkylamine.
