【Lecture Information】

This presentation summarises the author’s research in the area of laser fabrication of various micro/nano surface structures to tailor the material surface properties and their interactions with surrounding media. These include the tuning of wettability, optical properties of the surfaces including light absorption, reflection and scattering, aerodynamic properties, stiction force and friction coefficients of the surfaces, surface properties for bonding and adhesion, bio-compatibility, bacterial adhesion, dust adhesion of the surfaces. Nanosecond, picosecond and femtosecond lasers were used for these investigations. The applications of these special surface structures for data storage, security, medical implants, vacuum cleaners, light emission, solar energy harvesting, bone implants, coronary stents, dies and moulds, bonding and adhesion, and antibacterial surfaces and some of the associated mechanisms are described.
