Nanotechnology is one of the world's
most rapidly growing fields across a wide swath of industries from
pharmaceuticals to engineering. Nanotechnology refers to the many
disciplines in science and technology that benefit from controlling matter on
the atomic and molecular level, using the nanoscale for measurement. To place
the size in perspective, 25.4 million nanometers are in one inch.
Within the material sciences,
corrosion protection is an exciting area for the use and development of
nanotechnology. Protecting materials from corrosion is a big challenge in the
engineering and science world.
Today, one of the most vexing
problems facing the corrosion resistance community are rising prices of raw
materials such as zinc, lead, chromium and molybdenum. Another issue is the
marketplace wants environmentally friendly, "green" corrosion
coatings.
Last month, scientists from the
Institute for Color Science and Technology (ICST) in Iran discussed the results
from their research involving nanotechnology. They studied ways to improve the
quality of corrosion protection offered by coatings enhanced with modified
nanoparticles.
The research explored the effect of
impure zinc oxide nanoparticles doped with manganese and cobalt to tame the
corrosion problems in coatings and improve the quality of coatings.
According to Dr. Bahram
Ramezanzadeh, a member of the scientific board of ICST, the results of this
research will play a big part in solving the corrosion problems in industries
including:
- oil reservoirs
- oil and gas pipelines
- marine installations
- power plants
"In this research, we tried to
create corrosion-prevention behavior in addition to blocking properties by
doping zinc oxide nanoparticles with cobalt and manganese," Ramezanzadeh
said. "In addition, their surface was modified with silane agent to obtain
appropriate distribution of nanoparticles in the matrix of the epoxy
coating."
The use of zinc oxide nanoparticles
treated with cobalt and manganese improves the anti-corrosive coating by adding
two ways of enhancing corrosion prohibition properties and blocking corrosion.
Using the enhanced zinc oxide paste on metal increases the lifetime of metal
construction in hostile environments that lead to corrosion, cuts the use of
metal and increases the efficiency of the devices coated.
Over the past 20 years, researchers
have discovered new insights into how nanotechnology works and how its
scalability works for not only metals, but also for concrete, stucco and scores
of other materials that benefit from the corrosive protection added by
nanotechnology. Time will tell what new methods will be discovered in this
rapidly growing field.
