摘要：

In this paper the results of dielectric investigation of nanoconfined NaNO2 is presented. The phase transition is shifted to lower temperatures. Only one phase transition can be seen in the dielectric spectra and the intermediate incommensurate phase is suppressed. The increase in the frequency dependent dielectric permitivity on heating is mainly the result of a conductivity effects. The relaxational soft mode contribution is as well present, but is small as compared to the conductivity contribution. Such huge conductivity is caused by premelting phase, which is visible even at temperatures below the phase transition.
