Unconventional Nanomaterials
Our group focuses on unconventional nanomaterials free of critical raw materials and toxic compounds. We develop novel chemical strategies for synthesizing materials with unconventional size, shape, structure, and composition. Nanostructuring approaches, e.g., core-shell architectures, porous supports, functionalization, and self-assembly, are emphasized to enhance material performance. We prioritize sustainability and scalability of the chemical syntheses to align with industrial needs.
Research Areas
Coatings
We develop non-toxic, environmentally friendly functional coatings using unconventional nanomaterials. This approach combines nanostructuring, surface chemistry, and smart material design to achieve exceptional performance and sustainability. Our work includes the development of superhydrophobic coatings by tuning the nano- and micro-roughness of surfaces, without the use of fluorinated compounds, applicable to textiles, metals, and concrete. We also design smart coatings with self-healing properties that respond to physical and chemical triggers without external intervention. In addition, we create UV-absorbing coatings that avoid the photocatalytic effects of titanium, and infrared-reflective coatings for energy-efficient, environmentally responsible applications.
