Frictional patterning of a soft elastic polymer surface
MetadataShow full item record
In this study we show controlled patterning of a soft elastic polymer surface (polydimethylsiloxane (PDMS)) using Atomic Force Microscopy (AFM). PDMS has a broad range of applications, such as molecular stamps and use in biomedical devices, hydraulic fluid devices and soft lithography. In this work the polymer surface has been selectively altered by high speed scanning in order to generate regions on the surface which exhibit differentiated frictional properties. By altering the loading force, scan size, and contact dimensions of the AFM probe-polymer contact it is possible to produce a variety of detailed and complex frictional profiles, including anisotropic frictional gradients on the polymer surface. The controlled manipulation of the polymer surface can be carried out on the micro-, meso- and nano-scale.
