The resistance of composite films to moisture and oxygen has been studied. It has been established that under the influence of moisture and oxygen for 500 days, composite films perovskite(1:2) CH3NH3PbI3/polymer: PVB, COC, and PVDC degrade only by 1.55%, 1.65%, and 3.5%, respectively, which is 65, 60, and 29 times less than for pure perovskite CH3NH3PbI3. It has been found that the method of creating composite materials (mechanical deposition or sol-gel) affects the electrochemical characteristics of cathode materials. For the composite cathode material NMC 111, the capacity drop over 80 charge/discharge cycles is reduced by 10-14% compared to the original cathode material. The composite material NMC 111, produced by the mechanical deposition method, demonstrates a 4-6% better ability for the fast charge/discharge process compared to the original cathode material. It is shown that the creation of composite cathode materials with a high nickel content (NMC 811 and NCA) and LATP nanoparticles does not lead to an improvement in electrochemical characteristics. The criteria for selecting materials for creating composite resonant elements “non-magnetic dielectric resonator/ferrite film” are determined. The influence of film thickness and ferrite concentration on the properties of BaTi4O9-ZnO/Ni0.5Zn0.5Fe2O4 composite elements is investigated. The best results in terms of frequency shift and energy loss were found for films with a thickness of 100 μm and a ferrite concentration of 175 mg/ml. The resonator in which the ferrite film was polymerized in a field parallel to the resonator axis showed the best magnetic control results with a maximum frequency shift of 71 MHz. High non-reciprocity of electrophysical properties up to ~ 50 dB was established. Product Description popup.authors Lisovskyi Ivan V. Torchyniuk Pavlo V.
