Using nanodiamonds in material engineering enables
to create novel diamond nano-composites and to improve existing functional
materials exploiting the unique properties of diamond including:
-
Extreme mechanical hardness
98 GPa {111}
-
Highest wear resistance
-
Outstanding optical
properties
-
Wide band gap {300 K}: 5.47
eV
-
High refractive index:
2.419
-
Highest thermal
conductivity: 2300 W/mK
-
Very good electrical
insulation: 10¹³ ῼcm
-
Highest sound propagation
velocity
-
Chemical and radiation
resistance
-
Biological compatibility
and non-cytotoxity
However, to exploit these unique features of nanodiamonds
and create new composite materials with desired properties is not a simple task
because of the wide variety of functional groups causing aggregation and defining
different behavior of diamond crystallites in same reactions. Therefore, the
control of ND dimensions, purity and surface chemistry is highly important for
the implementation of this unique material in various fields of science, technology
and medicine. Intensive development of new formulations is also important for
market penetration of nanodiamonds in industrial scale.
RAY has developed technology for fabrication nanodiamonds
of high purity and homogeneity, as well as technology of nanodiamond surface
modification enabling disaggregation and uniform distribution of nanoparticles
in diverse media. RAY is looking for partnerships for the development of final
nanodiamond applications and commercialization of its technology.
