polyurethane), elastomeric materials (like silicone rubber), semiconduc-
tors, metals, ceramics, glass, and other materials. The adhesion of the
Tetracarbon TM coating is so high that it can be removed from the substrate
together with substrate material. Thus, its adhesion to many substrates is
higher than the substrate material strength. Samples of silicone rubber
coated with Tetracarbon TM were mechanically tested, including elongation
by 300% and multiple deformations; the coating withstood these tests
without visible damage, as no cracks or coating exfoliation were observed.
The high flexibility and elasticity are unique features of Tetracarbon TM .
The low friction coefficient (0.1-0.2) against metals, smooth and uniform
surfaces, and excellent adhesion allow Tetracarbon TM to be employed in
numerous applications. The unique characteristics of Tetracarbon TM can be
controlled and varied during its deposition, which allows customizing the
Tetracarbon TM coating for different applications.
In experiments on biomedical examination of Tetracarbon TM , the
absence of protein denaturation was found on its surface. It is also
characterized by exceptionally low blood coagulation potential, thus having
perfect blood compatibility. Figure 11.22 shows the rate of the clot growth
on the surface of different materials in comparison with the Tetracarbon TM
films. As can be seen in Figure 11.22 the Tetracarbon TM coating possesses
a record thrombus resistance and allows improving biocompatibility of
medical implants and devices, thus preventing thrombus formation and
reducing the risk of implant rejection or inflammation. Tetracarbon TM can
