The addition of poly (ethylene glycol) diglycidyl ether (PEDGE) as surface modifier and type of conductive fillers into poly (vinyl chloride) (PVC)/poly (ethylene oxide) (PEO) blends was studied. PVC/PEO blends conductive films with 15 wt% of carbon black (CB), poly (aniline) (PAni), and poly (pyrrole) (PPy) were prepared using solution casting technique. The addition of PEGDE showed lower tensile strength, but higher modulus of elasticity and electrical conductivity for all compositions of PVC/PEO conductive films. Scanning electron microscopy (SEM) results show that the addition of PEGDE in conductive films gives good dispersion between matrix and fillers. The PVC/PEO conductive films demonstrated less thermal stability with the addition of PEGDE compared to without PEDGE.

This research aimed to examine the effect of cellulose microfibrils (CMF) as a filler to thermal characteristics and morphology of bioplastic. Sorghum starch and chitosan, of which 63 micron particle size, were varied by starch to chitosan ratio (g/g) of 10:
