The idea that water molecules can be translated into a polar form of ice was introduced in early 1933 in a paper written by J. D. Bernal and R. H. Fowler. More recent studies have shown that low-dimensional polar ice can be obtained through dimensionality reduction in confined phases like in water filled carbon and inorganic nanotubes. However, in those systems the switchable bulk dipolar alignment of polar ice is difficult. Therefore, this pursuit has shifted to exploiting polar ice confined in crystalline voids. In this poster presentation, dielectric properties of 2,3,6,7,10,11-hexahydroxytriphenylene tetrahydrate cold pressed ceramics will be presented. The measurements of dielectric permittivity was performed using HP 4284A precision LCR meter and P(E) curves were obtained using AixACCT TFAnalyzer 2000 E system. The dielectric spectra show an anomaly at 256 K temperature. Furthermore, it can be noted that the temperature dependence curves are close to following the Curie Weiss law which is typical for improper ferroelectrics. A field of up to 60 kV/cm was used for P(E) measurements. No hysteresis loops were observed below the phase transition.
