DEVELOPMENT OF MATERIALS WHICH CHANGE BEHAVIOR IN RESPONSE TO EXTERNAL STIMULI
The surface behavior of the materials determines in many cases their suitability for specific applications.
In the direction of smart surfaces and smart materials in general, the development of materials which change behavior in order to respond to different external stimuli are of particular interest.
One approach for this purpose is the development of biomimetic materials, which try to mimic the behavior of objects that exist in nature, such as for example the superhydrophobic Lotus Leaf, the petals of a rose or the butterfly wings.
Dr. Spiros Anastasiadis, Professor of the Department of Chemistry of the University of Crete and Associate Researcher of the Institute of Electronic Structure and Laser of the Foundation of Research and Technology (FORTH), has received important awards in the field of polymers, conducting pioneer studies on the structure and dynamics of polymers in solutions, melts, interfaces and thin films.
Combining Physics with Chemistry
SMART - RESPONSIVE SURFACES
In the research laboratory, the team of Dr. Anastasiadis tries to combine the appropriate composition of the materials developed with the proper surface morphology, using the suitable laser sources to achieve the desired results.
Their aim is to controllably, reversibly and for many repeated cycles alter the surface wetting properties, which will respond to stimuli such as the acidity of liquid (pH), the wavelength of incident light, the temperature, the different solvents or the combination of the above. They currently focus on materials that alter their behavior from super-hydrophilic (right image) to super-hydrophobic and repellent to water (left image).
Such efforts could be applied in our daily life with the development of coating with self-cleaning properties or stain free fabrics, even with the creation of smart windows that regulate the intensity of the transmitted light.
Intensive efforts continue to take place, aiming in different applications, such as the anti-fouling property, i.e. materials that will not allow the deposition of biological materials on surfaces that are in the water, e.g., ships. In parallel, the team also works with material applications in the field of energy (e.g., organic photovoltaics).
