Based on magnetic-field-assisted growth of carbon nanofibers in an open ethanol flame we fabricated arrays of carbon nanofibers with different degrees of orientation. Inspired by the dry adhesive system of geckos we investigated the adhesive properti

The locally defined growth of carbon nanofibers with lambda shape in an open flame process is demonstrated. Via the growth time, the geometry of the structures can be tailored to a Λ- or λ-type shape. Microchannel cantilever spotting and dip-pen na

For their potential use as dry adhesives under harsh conditions as in space, we investigated the temperature dependence of the adhesion of carbon nanotube arrays by atomic force microscopy (AFM) from $$-\,20\,^\circ \hbox {C}$$ to $$+\,240\,^\circ \h

Publikováno v: European Polymer Journal. 52:154-165

Scanning Probe Tomography (SPT) is a new method for nanoscale volume imaging of sample morphology and property distribution based on Scanning Probe Microscopy (SPM). In this review we describe and discuss recent results obtained with different SPT te
