Combining a Fluoroalkylsiloxane and Ion Implantation for Hydrophilic/Hydrophobic Patterning

Cook M.J., Johnston J.H., Leveneur J., Victoria University of Wellington, NZ

We present a novel method of producing hydrophilic/hydrophobic patterning on several different substrates using a novel two-step process. The developed process involves a simple surface functionalization with a fluoroalkylsiloxane (FAS), followed by masked ion implantation. [...]

Durable Super-Hydrophobic Nano-Composite Films

Chinn J., Integrated Surface Technologies, US

A new durable super-hydrophobic coating has been invented that protects cell phones and other portable electronic products from water or other liquid damage. The printed circuit boards of these consumer oriented products are placed into [...]

Nanostructured and Self-Assembled Superhydrophilic Bipolar Plate Coatings for Fuel Cell Water Management

Dadheech G., Abd Elhamid M., Blunk R., General Motors Corporation, US

A stably superhydrophilic coating is required on composite and metal bipolar plates to manage byproduct liquid water and, in turn, to enable good PEM fuel cell performace under low power vehicle operating conditions. Silica-based coatings, [...]

Durable Anti-Stiction Coatings by Molecular Vapor Deposition (MVD)

Kobrin B., Chinn J., Ashurst R.W., Applied Microstructures, Inc., US

Development of new SAM coatings using a “sequential” vapor technique which can be deposited on almost any substrate material and withstand harsh environments is reported. Technical benefits for the improved surface modification method called Molecular [...]

An Effective Passive Micromixer Employing Herringbone Structure

Kung C-F, Chen C-F, Chu C-C, Tseng F-G, IAM, National Taiwan University, TW

This paper proposes a high efficient micro mixer, passively employing surface tension force as driving power and Herringbone structures as vortex generator for fluid mixing. The fluidic channel was designed without sidewall and confined with [...]
