The prospects of using biopolymer nano-containing films for wound healing were substantiated. The main components of biopolymer composites are gelatin, polyvinyl alcohol, glycerin, lactic acid, distilled water, and zinc oxide (ZnO) nanoparticles (NPs). Biopolymer composites were produced according to various technological parameters using a mould with a chrome coating. The therapeutic properties of biopolymer films were evaluated by measuring the diameter of the protective effect. Physico-mechanical properties were studied: elasticity, vapour permeability, degradation time, and swelling. To study the influence of technological parameters of the formation process of therapeutic biopolymer nanofilled films on their therapeutic and physico-mechanical properties, the planning of the experiment was used. According to the results of the experiments, mathematical models of the second-order were built. The optimal values of technological parameters of the process are determined, which provide biopolymer nanofilled films with maximum healing ability (diameter of protective action) and sufficiently high physical and mechanical properties: elasticity, vapour permeability, degradation time and swelling. The research results showed that the healing properties of biopolymer films mainly depend on the content of ZnO NPs. Degradation of these biopolymer films provides dosed drug delivery to the affected area. The products of destruction are carbon dioxide, water, and a small amount of ZnO in the bound state, which indicates the environmental safety of the developed biopolymer film.

By changing the temperature of chemical activation of plant biomass, nanoporous carbon materials with a specific surface area of up to 1050 m2/g were obtained. The obtained carbon materials were used to form composites with different percentages of conductive additive. Electrochemical impedance spectroscopy was used to investigate the physicochemical processes occurring at the carbon electrode/electrolyte interface in a 30% aqueous KOH solution. The concentration of charge carriers in the obtained carbon materials was determined, the values of which are in the range of 6·1018 – 35·1018 cm-3, and its dependence on the temperature of thermochemical activation was established. It was established that an increase in the temperature of thermochemical activation from 600 ºС to 900 ºС leads to an increase in the capacity of the space charge region by almost 10 times. The formation of nanoporous carbon material/conductive additive composites contributes to the correlation between the values ​​of specific capacitance and electrical resistance for the studied materials.
