The relevance of creating coatings based on polymer blends is driven by the challenges of modern materials science, which include obtaining materials with specified performance characteristics by changing the composition of chemical systems and studying their properties. This paper presents the results of a study of the structural, mechanical characteristics and surface wettability of nanostructured films based on polymer blends of polyvinylcarbazole (PVK) and poly(methyl methacrylate) (PMMA). PVK, PMMA and PVK-PMMA films were formed using the Langmuir – Blodgett (LB) method via horizontal deposition onto the pre-hydrophilized silicon substrates. A correlation has been established between atomic force microscopy (AFM) data of the structural, mechanical properties and the wettability of the polymeric coatings. It was shown that at PVK mass content of up to 45% in the polymer blend solution, the formed LB films are characterized by a disruption of a structural integrity and the formation of spherical and elongated conglomerates. According to static force spectroscopy data, the local values of the elastic modulus and adhesion force of LB films based on PVK-PMMA blends aren’t depend on the quantitative ratio of components. The water contact angle (CA) values for the polymer blends ranged from 74.31° ± 1.21° to 80.11° ± 1.55° and are determined by the properties of the component whose mass content is predominant. The formation of a dense LB film based on a polymer blend with significantly different molecular weights is possible when the low molecular weight component content in the blend is up to 15 wt. %, which is confirmed by AFM data for the PVK-PMMA sample with a component mass ratio is of 87.1 % – 12.9 %. The wettability of this film differs from that one of the homopolymer samples, which expands the application prospects of these polymers.
