Были получены нанокомпозитные материалы (ÐКМ) на оÑнове ионных жидкоÑтей BMIMTFSI, BMIMOTF и BMIMDCA, внедренных в нанотрубки галлуазита и хризотил-аÑбеÑта различной длины. Полученные наногели на оÑнове нанотрубок, заполненных ионными жидкоÑÑ‚Ñми, обладают выÑокой ионной проводимоÑтью, что делает такие материалы перÑпективным Ð´Ð»Ñ Ð¿Ñ€Ð¸Ð¼ÐµÐ½ÐµÐ½Ð¸Ñ Ð² Ñфере ÑлектрохимичеÑкой Ñнергетики. ИÑÑледованы диÑлектричеÑкие ÑвойÑтва ÐКМ в температурном диапазоне от 300 K до 420 K на измерительных чаÑтотах от 0.1 Гц до 3 МГц. Показано, что увеличение длины нанотрубок приводит к уменьшению диÑлектричеÑкой проницаемоÑти и проводимоÑти ÐКМ. Уменьшение объема аниона ИЖ приводит к увеличению диÑлектричеÑкой проницаемоÑти и проводимоÑти ÐКМ.

Nanocomposite materials based on ionic liquids: BMIMTFSI, BMIMOTF, BMIMDCA embedded in nanotubes of halloysite, and chrysotile asbestos of various lengths were obtained. Nanogels based on nanotubes filled with ionic liquids have high ionic conductivity, which makes such materials promising for use in the field of electrochemical energy. Dielectric was studied in the temperature range from 300 K to 420 K at frequencies 0.1 Hz to 3 MHz. An increase in the length of the nanotubes leads to a decrease in the permittivity and conductivity. A decrease in the volume of the anion leads to an increase in the permittivity and conductivity. The ProFit application program is used for nonlinear approximation of frequency spectra. As a result of the analysis of the dielectric response, three relaxation processes were revealed in the studied temperature and frequency ranges. Two of them characterize the relaxation properties of the IL, while the other is associated with electrodes polarization. Decomposition temperatures for some of the studied NCM have been revealed. A comparison of the conductivity of the studied NCM with the initial IL was carried out.
