“…From the graph, we understood that resistance of the thermistor decreases almost linearly (i.e. quasi linear behavior) with increase in temperature [18]. The resistivity obtained in this work can be primarily attributed to the grain size of the samples.…”

We have demonstrated the successful preparation of polyvinyl alcohol (PVA) composed CuBi 2 S 3 polyionic (PI) composites. Polymer composites were sensitive to the external stimuli, the modified PVA moiety exhibits excellent electrical property as a function of temperature. The volume resistance measured by impedance analyzer (40 to 150 o C) under broadband frequency (50Hz -1MHz). The negative temperature coefficient (NTC) was observed in the temperature range of 40 to 150 o C. It offers the nonlinear resistivity, ρ = 10 5 (Ω-m) across pure PVA moiety. The influence of polycationic-ions crucial to obtain the gradual decrease of resistivity (ρ) up to 10 4 (Ω -m ). The thermistor characteristics were disclosed as function of polyionic loading (wt %).

In the present study, we have fabricated the blends of polyvinyl alcohol (PVA) and cross linked chain extended cationic polyurethane binder (PUB). X-ray diffraction (XRD) reveals that the crystallinity decreases with PUB loading. The hydrogen bonding of PVA and PUB are confirmed by shifting of C=O (1750-1700 cm −1 ) and N-H resign (1400-1380 cm −1 ) of Fourier transform infrared spectroscopy (FTIR) spectra. The optical properties of the blend system such as direct and indirect band gap were evaluated by UV absorption spectra. The band gap decreases with the loading of PUB. The miscibility of PUB and PVA blend has been confirmed by differential scanning calorimetry (DSC). It shows a decrease in glass transition (T g ) and decomposition temperature (T d ), and increase in melting temperature (T m ) with PUB loading. The plane morphology of blend was confirmed by scanning electron microscopy (SEM) with better homogeneity (for 50 % PUB loading). The frequency-dependent AC conductivity seems to follow Jonscher power law in which power factor (s) varies in the range 0.74
