The biocompatibility Today, the carbon materials have been the one of best biocompatibility materials.
Espically, the carbon materials maked by isothermal chemical vapor infiltration (ICVI) had represented as artificialy heart valve materials with the highest level, and had been also applied wildly to clinic.
The artificialy heart valve and eardrum repair materials also had been studied.
The resulits show that moderate rigidity, toughness, porous and toughness of this kind of materials is perfect artificialy bone repair materials.
