Carbon nitride thin films as protective coatings for biomaterials: synthesis, mechanical and biocompatibility characterizations

Metal and Ceramic Implants

“…This reaction is neither chemical nor physiological, but is a physical and mechanical effect (Oppenheimer effect). The problem has been resolved by the addition of epoxy resins to harden the carbon fiber agglomerate or by vitrifying processes of the implant surface (e.g., pyrolytic carbon; Hetherington et al 1995) or diamond-like carbon coating (Kornu et al 1996;Tessier et al 2003). In the first case, a toxic element is added which is easily detectable after incomplete polymerization.…”

Spectroscopic ellipsometry characterization of amorphous carbon and amorphous, graphitic and fullerene-like carbon nitride thin films

“…Numerous types of structures of C and CN x have been produced since then and several of the structures show interesting mechanical, tribological, electronic and optical properties making them promising candidates e.g. as tribological coatings [3], as protective layers on magnetic hard disks [4], as filler in electrical conductive adhesives [5], and as a biomaterial [6,7]. In the context of biomaterials, one group of carbon-based materials should be mentioned in particular, the fullerene-like CN x, discovered in 1995 [8][9][10].…”

Surface energy and hybridization studies of amorphous carbon surfaces

“…Owing to their wide range of properties [9], amorphous carbon surfaces have received a special attention particularly focused on their biocompatibility/ haemocompatibility when used as biomedical implant coatings [10][11][12][13][14][15] or on their interactions with molecular additives in the case of hard disk or solid lubricant coatings [16,17]. Amorphous carbon has also been used as anti-stiction coating in MEMS [18].…”
