Polymethyl methacrylate (PMMA)/polyvinyl acetate (PVAc)/tetra-n-butylammonium iodide (TBAI)/ x wt % polyaniline (PANI) blended polymers are fabricated using the casting method to operate in energy storage purposes. The structure and morphology of created blends were studied X-ray diffraction (XRD) scanning electron microscope (SEM) techniques. XRD analysis displayed that semicrystalline behavior polymer blend is unaffected by doping. At 293 K 100 Hz, dielectric constant decreased from 22.7 (undoped) 14.04–21.7 depended on amount PANI doped blend. greatest density ( U ) values reported with = 0.33; 0.00469 J m −3 at Hz.
