Research Interest:
Our research primarily focuses on surface engineering, corrosion science, paints and coatings, passivation, superhydrophobic coatings, and coatings for biomedical applications.
Corrosion and Coatings:
Corrosion significantly impacts both the economy and human safety, with approximately 6–7% of GDP lost due to corrosion-related damage. One of the most common methods for corrosion mitigation is the application of barrier coatings. Although a wide variety of coatings are commercially available, our research is dedicated to the development of advanced and sustainable coating systems. A key area of our work involves the development of paints derived from plastic waste, promoting sustainability and waste management. Additionally, we focus on designing specialized coatings for rusted surfaces to enhance durability and corrosion resistance.
Passivation and Corrosion Inhibitors:
Passivation is another effective strategy for corrosion prevention. Our research aims to develop highly efficient, low-cost, eco-friendly, and biocompatible corrosion inhibitors. We place special emphasis on inhibitors for copper and its alloys, which are widely used in electronics and various industrial applications. The inhibitors developed by our group demonstrate significantly higher corrosion inhibition efficiency compared to commercially available alternatives.
Coatings for Orthopaedic Implants:
We focus on the development of smart, grafted polymer coatings for metallic orthopaedic implants to prevent metal ion leaching. These bioactive and biodegradable coatings are biocompatible, corrosion-resistant, and possess antibacterial properties, effectively addressing critical challenges in bone and dental implant applications.
Hydrogels and Their Applications:
The development of injectable hydrogels through novel cross-linking methodologies for in situ formation has gained significant attention in both fundamental and applied research. Various physical and chemical cross-linking strategies have been employed to construct advanced hydrogel systems. Our research particularly focuses on multi-stimuli-responsive hydrogels (MSRHs), which respond to factors such as pH, light, ionic strength, magnetic fields, and chemical triggers. These hydrogels hold immense potential in biomedical engineering, tissue engineering, and drug delivery, making their development a key focus of our research group.
