hen developing new, commercially available products, nanostructured materials are receiving an increasing amount of
interest. Transition from fossil fuel to sustainable sources of energy is essential. Solar energy is a promising alternative
energy source that can address this challenge. Platelets graphene as flake like material is one of the nanomaterials suitable
for improvement of spectrally selective coatings. Synthesized platelets graphene was used as a corrosion protection agent
while also serving as a solar absorbing pigment. The main obstacle in the synthesis of platelets graphene is agglomeration of
the particles, thus they have to be functionalized. With the functionalization of the particles the application of the prepared
dispersions is simple and infusion of platelets graphene less evident. High absorptivity is expected due to the platelets graphene
structure. The latter is also a candidate for an improvement of the corrosion inhibition effect. Raman spectroscopy, atomic
force microscopy and transmission electron microscopy were used to characterize prepared platelets graphene (especially
for the definition of the layers) and coatings. In addition to the proposed techniques, the Fourier Transformation Infrared
Spectroscopy and UV-Vis spectroscopy were introduced to characterize optical properties of the coating. The presented results
demonstrate improvements of spectrally selective coatings for low temperature application.
Biography
Ervin Šest has his expertise in evaluation and passion in improving the sustainable energy resources. He is developing and preparing innovative paint coatings for
solar application. He is also evaluating the prepared materials and applied coatings. He obtained a degree in the field of dye sensitized cells and developed effective
method of sintering TiO2 as the working electrode. Now, he is a Young Researcher at the National Institute of Chemistry Slovenia and studying Nanosciences and
Nanotechnologies at the Josef Stefan International Postgraduate School. His research interests include sol-gel thin films; modification of pigments for spectrally
selective paint coatings; surface treatments and nanocoatings; dye sensitized solar cells; electron microscopy, sample preparation.
