In this study, surfactant dispersed MWCNTs were introduced as nanofillers into poly (vinyl) alcohol (PVA) and Chitosan (Cs) blend (ratio 50:50 wt%, optimized) by solution casting method to fabricate PVA/Cs/MWCNTs nanocomposite films. These nanocomposites were subjected to different characterization to study the variation of properties with different amount of MWCNTs loading. Various techniques, such as Optical microscopy (OM), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA, DTGA), differential scanning calorimetry (DSC), impedance analyzer (IA), scanning electron microscopy (SEM) and universal testing machine (UTM) were used to study the physicochemical, morphological, electrical and thermo-mechanical properties of the nanocomposite films. The experimental results of FTIR illustrated that strong interaction among MWCNTs, Cs and PVA facilitated the crystallization of PVA and prevented the agglomeration of MWCNTs in the composite film. Tensile strength of the nanocomposite containing 1 wt% MWCNTs increased by 61.51% and elongation at break decreased by 20.07% in comparison to that of pure PVA/Cs blend film. Similarly, the conductivity of the nanocomposite containing 1 wt% MWCNTs was highest at 40V with the value of 1.99 x 103 S/cm.
