Wettable Slippery Surfaces. Self-cleaning Effect and Mechanism

Law K-Y, Research and Innovative Solutions, US
The phenomenon of self-cleaning displayed by the Lotus leaf and many other plant and insect surfaces has attracted tremendous attention recently. Self-cleaning surface is usually superhydrophobic and non-wettable, and is characterized by a very large [...]

Design Parameters for “Robust” Superoleophobicity Surfaces

Law K-Y, Zhao H., Park K.C., Xerox Corporation, US
Earlier we reported the fabrication of a model superoleophobic surface comprising ~3-micron diameter pillar arrays on Silicon. Results showed that both surface fluorination and the re-entrant geometry are crucial in achieving the superoleophobicity with hexadecane [...]

Adhesion of Water on Flat Polymer Surfaces and Superhydrophobic Surfaces

Law K-Y, Zhao H., Samuel B., Xerox Corporation, US
The interaction of water droplet with flat polymer surfaces of varying hydrophobicity (contact angle) has been studied using a high-sensitivity microelectromechanical balance system (tensiometer). Both attractive force and pull-off force are studied as the water [...]

Novel Electrostatic Digital Printing Device Based on Single Walled Carbon Nanotube

Law K-Y, Kanungo M., Xerox Corporation, US
Carbon nanotube thin films because of their unique optical and electronic properties coupled with the flexibility and easy patternability are promising candidates for application in low cost, large area flexible displays and optoelectronics. In this [...]

Effects of Surface Texture and Chemistry on Surface Hydrophobicity and Oleophobicity

Law K-Y, Zhao H., Sambhy V., Xerox Corporation, US
The effects of surface texture and chemical modification on the hydrophobicity and oleophobicity of the resulting surfaces have been systematically investigated. The surface textures were created by the conventional photolithographic technique on Silicon wafer. This [...]
