“…Experimental and Theoretical Aspects of the Modern Nanotribology Some of the measurements have revealed double tips and other unsuitable tip structures [118,119]. Thus, tip characterization is absolutely necessary for AFM imaging, precise determination of the forces and nanotribology experiments.…”

A review is given of the present day problems related with experimental and theoretical studies in nanotribology, a new apatterning branch of physics, which pertains to investigations of the atomicscale friction, adhesion, wear and lubrication. When analysing the experimental results a major point of interest is related with ªdryº adhesion friction between the tip of an atomic force microscope and an atomically smooth surface. However, many other physical effects are considered, too, such as chemical ones, triboemission of particles, conduction in metallic nanocontacts, etc. For the first time, some new results in theoretical elaborations of adhesional (static) and dynamical (velocity-proportional) friction are discussed, as well as some results obtained using the computer simulations. A brief discussion of nanostructural friction measured with the quartz crystal microbalance technique and the surface-force apparatus is also given.

“…Probing a polymer surface in the con-Fax: +49-731-502 2883 tact mode of SFM often leads to blurred and smeared images because the surface of the relatively soft polymers becomes deformed upon interaction with the probe [21,22]. Suitable tips can be selected routinely by means of a well-defined stepped single-crystal surface [24]. Suitable tips can be selected routinely by means of a well-defined stepped single-crystal surface [24].…”

The fibrillar structure of gel-drawn ultrahigh molecular weight polyethylene was studied by scanning force microscopy (SFM), transmission electron microscopy (TEM) and 'H-NMR. Periodically striped 20-50 nm wide nanofibrils were depicted at the surface of the ultradrawn tapes. A periodicity of about 25 nm was observed independently of the draw ratio in the range 10 = A S 70. This is consistent with the long period derived from SAXS experiments. The stripes were more pronounced at low draw ratios and a short range interfibrillar correlation was detected in that case. Based on variations in the 'H-NMR relaxation times and segment orientation, it is concluded that structural defects are concentrated within small domains inside the crystallites and that the striped structure originates from defect layers within the fibrillar crystallites.

“…Additionally, blunt tips are unable to reach down into narrow valleys to image the surface at the bottom of these valleys. These and other artefacts originating from convolution of the tip shape with the surface topography have been discussed elsewhere [224][225][226].…”
