Micropatterning of superhydrophobic silicone nanofilaments by a near-ultraviolet Nd:YAG laser


Stojanovic, A; Artus, G R J; Seeger, S (2010). Micropatterning of superhydrophobic silicone nanofilaments by a near-ultraviolet Nd:YAG laser. Nano Research, 3(12):889-894.

Abstract

We demonstrate that a recently developed coating comprised of superhydrophobic silicone nanofilaments can be selectively functionalized to yield well defined micrometer scale patterns of contrasting wettabilites (superhydrophobic/hydrophilic and amphiphobic/amphiphilic). Nanofilament ablation have been performed by near‐ultraviolet (UV) laser at 355 nm and with repetition rate of 10 kHz. This is a highly promising approach for open channel microfluidics and micro array analysis due to its simplicity, chemical and environmental stability of coating and low coast.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
