Smart Coatings Have Become Popular Among Several Industries Including Automotive and Aerospace Industry
Smart Coatings are polymer coatings that change their
properties significantly in response to external stimuli. These include
temperature, pH, moisture, surface contact, and so forth. Some of these
properties may be beneficial, such as anti-icing. Others, such as self-healing
or easy cleaning, may be undesirable.
Several types of smart
coatings are being developed to address the needs of these end use
industries, and they are also gaining widespread interest among researchers.
These coatings can help improve efficiency in the system by reducing inspection
times, maintenance costs and equipment downtime, and also provide protection
against corrosion and other environmental conditions. One major challenge to
the development of smart coatings is translating laboratory-proven concepts
into practical coating systems. This is particularly true for reversible
rearrangement of polymer structures that change surface properties.
Other challenges include health and safety regulations, the
methods of application and cure regimes currently available, and cost
constraints imposed on the target markets. Nevertheless, Jackson notes that the
development of smart coatings has been fueled by advances in both polymer
chemistry and technology. Along with improving performance, smart coatings can
reduce maintenance costs and energy usage. These features are appealing to
manufacturers and end-use customers alike, and they are driving growth in the
industry.
These Smart Coatings are widely used in the aerospace and automotive industries
as they are able to reduce the need for costly repairs. Moreover, these
coatings provide better protection against abrasion and scratching. Increasing
interest in autonomous vehicles has led to the need for functional coatings
that can help prevent dirt, water droplets, frost, and salt from accumulating
on camera lenses or LiDAR sensor windows. This can help maintain the
reliability of these components and sensors, thereby enhancing the user
experience.
This is an especially important issue for autonomous
vehicles, which rely on these components to map and sense their surroundings,
according to Peczonczyk. Thus, preventing the accumulation of these materials
on these components can significantly increase their lifespan. In April 2021,
AkzoNobel entered into collaboration with Qlayers, a startup and acquired a
share in a novel industrial coating application technology.
