“Using Nanocoatings Might Become a
Global Approach in Most Industrial Fields”
NANOTECHNOLOGY CAN BE APPLIED TO DEVELOP NEW AND ADVANCED MATERIALS
; Nanotechnology has a range of appli-catons. Andriy Voronov, associate professor of Coatings and Polymeric Materials at North Dakota State University,
describes the benefits and drawbacks
of nano-based coatings and offers an
outlook on future developments.
;;;Nanotechnology has become a subject of debate; what are your thoughts?
Andriy Voronov: Nowadays, about 900
everyday commercial products rely on
nano-size materials. It is not surprising
because nanotechnology can be applied
to develop new and advanced materials
of unique functionality and performance.
However, it is also true that size-depen-dent change of properties of the materials in the nanoscale range (including
their chemical reactivity) might bring not
only unprecedented benefits, but also
cause uncertainties and even health issues. In particular, nanoparticles can
cause some unknown effects being in
living organisms. In addition, studying
nanomaterials’ toxicity (nanotoxicology)
is an emerging field, where knowledge
about (nano)size and properties effects
on material toxicity still remains limited.
;;;In which coatings segments will
nanotechnology gain more influence in
the near future?
Voronov: In the future, many specific
features and properties of various materials may be addressed by incorporating
nanoparticles in formulations of different coatings. In fact, using nanocoatings
might become a global approach in most
industrial fields since new materials are
highly demanded in the marketplace.
Transportation, infrastructure, human
health and medicine, defense and security, electronics and information technology, environmental remediation, and
sustainable energy all may benefit from
using nanocoatings in the future, and
not only improve, but even revolutionize
some of them.
;;;Which nanotechnology-based
coatings developments do you consider
especially interesting?
Voronov: Different types of both or-
ganic and inorganic coatings can benefit
from using nanoparticles/nanofillers in
various applications. The paint industry
uses nanoscaled additives in formula-
tion of special purpose paints, as well as
for enhancing protective coatings’ per-
formance. Application of nanotechnol-
ogy in the corrosion protection of met-
als has been underway globally in the
last two decades. In machinery, greater
toughness in comparison to conven-
tional wear-resistant coatings has been
