Аннотация:The synthesis of phosphate-modified zirconia nanoparticles in pores of a polynaphthoylenimide-
based membrane material has been carried out via an in
situ method. The transport properties of the obtained
samples have been studied. It has been shown that doping
leads to an increase in the ionic conductivity of the
membranes. According to the impedance spectroscopy da
ta, the highest ionic conductivity upon contact with
water is reached for samples with a dopant content of 1–2%. At the same time, samples with a higher dopant
content retain a sufficiently high conductivity even under air-dry conditions.
