Natural Polysaccharide

Natural biodegradable and biocompatible polysaccharides chitosan, pectin, carrageenan and heparin were used to form thin nanostructured films. In this study using atomic force microscopy (AFM) and force spectroscopy the special characteristics of formation and structure of thin coatings were investigated, three models of the polymers interaction were proposed. Different mechanisms of polymers influence on each other in the bilayers formation were shown, coatings with different surface structure and mechanical properties were formed. The obtained data can be used for the preparation of nanostructured coatings with desired surface parameters.

ABSTRACTMgO thin films were deposited on silicon and sapphire substrates using ion-beam reactive sputtering. Films have been analyzed using x-ray diffraction, transmission electron microscopy, and atomic force microscopy. Highly oriented (100) MgO films have been obtained on Si (100) substrates. The in-plane orientation is predominantly [100]MgO//[100]Si, although a twist of up to ±10° between grains is observed. Epitaxial films of MgO were deposited on four different orientations of sapphire. The MgO film orientation was (111) on c-cut (0001) Al2O3 and exhibited double positioning boundaries in TEM analysis. On r-cut (1102) Al2O3, the MgO appeared to be oriented (730) with tilt and twist of ±2° between the grains. Epitaxial MgO films oriented (110) and (111) were obtained on m-cut (1010) and a-cut (1120) sapphire orientations, respectively. In-plane directions were extracted from TEM analysis on all the samples. Atomic force microscopy revealed fairly smooth MgO films on sapphire, varying from 0.35 nm average roughness for the MgO film on the m-cut substrate to 0.80 nm on the r-cut substrate.

In this work, a mechanically durable anticorrosion superhydrophobic coating is developed using a nanocomposite coating solution composed of silica nanoparticles and epoxy resin. The nanocomposite coating developed was tested for its superhydrophobic behavior using goniometry; surface morphology using scanning electron microscopy and atomic force microscopy; elemental composition using energy dispersive X-ray spectroscopy; corrosion resistance using atomic force microscopy; and potentiodynamic polarization measurements. The nanocomposite coating possesses hierarchical micro/nanostructures, according to the scanning electron microscopy images, and the presence of such structures was further confirmed by the atomic force microscopy images. The developed nanocomposite coating was found to be highly superhydrophobic as well as corrosion resistant, according to the results from static contact angle measurement and potentiodynamic polarization measurement, respectively. The abrasion resistance and mechanical durability of the nanocomposite coating were studied by abrasion tests, and the mechanical properties such as reduced modulus and Berkovich hardness were evaluated with the aid of nanoindentation tests.
