The paper presents the results of the research on the formation of nanocomposite fluoroplastic thin-wall coatings on substrates: 45 steel; copper and Al, formed under various conditions using the method of atomic force microscopy. Morphological features of the nanophase thin-layer fluoroplastic coatings with disperse nanoparticles have been studied. A model for the formation of nanophase composite systems is proposed.

ABSTRACTThe effects of both temperature and atmosphere on the resulting morphological features of the polar faces of single crystal ZnO were investigated and characterized by atomic force microscopy (AFM). In studies where ZnO was thermally processed in flowing oxygen at atmospheric conditions within the temperature range of 500°C to 900°C for 30 minutes, the Znsurface (i.e., (000 1)) showed a tendency to reconstruct with increasing temperature until terraces became evident at 900°C. Terrace heights were as small as 0.9 nm. In contrast, the O-surface (i.e., (000 ī)) was observe to change very little during the O2-atmoshere, thermal treatment and remained comparatively rougher than the Zn-surface. ZnO samples which were thermally processed under high vacuum (i.e., 5 × 10-7 Torr) conditions exhibited a more dramatic contrast. The vacuum annealed Zn-surface was observed to develop very smooth surface features (Roughness = 0.09 nm) at annealing temperatures within the 700 – 800°C range. In contrast, and as expected, the O-surface roughness increased due to surface reduction reactions. In addition to these findings, it is noted that AFM measurements may be utilized as a convenient method to distinguish between the two polar surfaces of ZnO.Aluminum nitride was deposited on the Zn- and O- surfaces from 700 to 850°C by pulsed laser evaporation. X-ray diffraction indicated that the AIN was c-axis oriented with no interface reaction products detected between the ZnO substrate and AIN film.

The results of studies of the structure, mechanical and tribological properties of composite materials based on polytetrafluoroethylene and simple (Al2O3, Cr2O3, ZrO2) and complex (spinels CoA12O3 and MgAl2O4, and cordierite 2MgO—2Al2O35SiO2) oxide nanopowders are presented; as well as amorphous polyvinyl chloride with heat stabilizers and elastomeric additives. Investigations of thin-layer fluorine-containing coatings with a polymer matrix modified by nano- and ultra-fine particles of diamond-containing graphite by atomic force microscopy are presented.

Surface morphology of Fe(III)–porphyrin thin layers was studied using atomic force microscopy. The thin layer samples used in these experiments were deposited by spin coating methods on indium–tin-oxide substrates at room temperature under atmospheric conditions. Variations of thin layer of Fe(III)-porphyrin were done by modifying the rotational speed and the concentration of the solution. The experimental results demonstrated that the Fe(III)–porphyrin layers were observed as discrete nanomolecular islands. Both the number of nano-islands and thickness of the layer increased significantly with increasing concentration. A layer thickness of 15 nm was obtained for low concentrations of 0.00153 M and become 25 nm for dense concentrations of 0.153 M. Conversely, the higher number of islands were deposited on the surface of the substrate at a lower rotational speed.
