Abstract
Abstract This work reports experimental results for investigating the effects of residual water on phase transition in triglycine sulfate (TGS) filled with 5 wt% of oxidized multiwalled carbon nanotubes (OMWCNTs) under a relative humidity of 90% for different storage time. A similar composite containing TGS and non-oxidized MWCNT was also synthesized for comparison. According to measured data, the moisture was well adsorbed into OMWCNT/TGS composite and resulted in the shift of phase transition point toward higher temperatures for samples stored for less than 5 days. The longer storage caused a significant drop of dielectric constant at phase transition.
期刊介绍：
Ferroelectrics Letters is a separately published section of the international journal Ferroelectrics. Both sections publish theoretical, experimental and applied papers on ferroelectrics and related materials, including ferroelastics, ferroelectric ferromagnetics, electrooptics, piezoelectrics, pyroelectrics, nonlinear dielectrics, polymers and liquid crystals.
Ferroelectrics Letters permits the rapid publication of important, quality, short original papers on the theory, synthesis, properties and applications of ferroelectrics and related materials.
