Investigation of the Effect of Superhydrophobic Coatings on the Performance of Heat Exchangers
… of this project was to investigate the effect of superhydrophobic coatings on the performance of aluminium louvered fin heat exchangers. A method was developed to prepare superhydrophobic coatings on the exchangers by applying layer of metallic zinc and then reacting the zinc-coated exchanger with …

Natural and engineered surfaces for enhanced phase change heat transfer
… materials for environmentally friendly superhydrophobic coatings. Furthermore, we answer a key scientific controversy regarding the wettability of rare earth oxides by conclusively showing that hydrophobicity is driven by hydrocarbon adsorption. The findings were leveraged to design, …

Micron-scale liquid engineering for porous polymer patterning
… from insulation and impact absorption to superhydrophobic coatings, controlled drug release materials, biological scaffolds and photonic materials. Different approaches such as lithography, etching and direct templating were developed to produce porous polymers. There is still a huge …

Investigations on Multiscale Fractal-textured Superhydrophobic and Solar Selective Coatings
Functional coatings produced using scalable and cost-effective processes such as electrodeposition and etching lead to the creation of random roughness at multiple length scales on the surface. The first part of thesis work aims at developing a fundamental mathematical understanding of multiscale …
