• Soft polymer composites

Soft polymer composite (SPC) was prepared by mixing a polyvinyl alcohol (PVA) host system with conducting carbon black (CCB) as a single nano entity (SNE) and CCB+Montmorillonite (MMT) clay as mixed nano entities (MNE). The modified crystalline phase to amorphous exhibits the impact of filler. The destroyed crystalline phases are also evident from XRD spectra where interplanar distance decreased. Addition of MNE resulted in inhibition of foreign bond formation and also prevented stretching and bending of substrate molecules, which were detected by Fourier Transform Infrared (FTIR) spectroscopy. The morphology of SPC was studied by optical and scanning electron microscopy (SEM). Improvement of glass transition temperature (Tg), Young's modulus and AC conductivity was observed as a function of SNE and MNE loading.
