Thermodynamic approaches were used to investigate the antibacterial
property of diamond-like carbon (DLC) films containing titanium
dioxide (
) nanoparticles. The films were grown on 316L
stainless steel substrates from a dispersion of in hexane using plasma enhanced chemical
vapour deposition. The composition, bonding structure, surface energy,
and work of adhesion of these films were evaluated. The results were
compared to practical antibacterial tests. As content increased, there was an increasing
in ratio, the films become more hydrophilic,
with higher surface free energy and the interfacial energy of bacteria
adhesion decreased. The results show that the antibacterial activity
of -DLC films is directly influenced not only by
the increased concentration of nanoparticles, but also by the ratio, wettability, and work of adhesion of
these films.
