Abstract Modified polymer blends demonstrated the desirable properties and performance suitable for various applications. In the present investigation, we prepared the blends of crystalline Polyvinylidene fluoride (PVDF)/ with amorphous Polysulfone (PSF) by a solution technique. We have foreseen the miscibility of the PVDF/PSF polymer system by an optical polarizing microscope. The electrical quality factor (Q) of these polymer blends demonstrated increased quality magnitude with the shift in resonance frequency (f0 ) and bandwidth (B.W.) confirmed by an impedance analyzer. The influence of the temperature on the quality factor was studied across the temperature scale (30 to 150 ◦ C). This investigation was feasible for the development of a new class of polymer blends deployable for electronics and shielding applications.

1 Introduction In the modern era of engineering materials the research community derived polymermodified blends, matrices and hybrid composites with outstanding desirable properties. Polymers are classified based on the origin of source, structure, molecular weight and degree of polymerization. Natural, semi-synthetic, and synthetic polymers are classified based on the origin or source. Linear, branched-chain and cross-linked polymers are the class of structural polymers. Elastomers, fibers, thermoplastics and thermosets belong to a molecular forces-based class of polymers whereas, addition and condensation polymers belong

to a polymerization-based class of polymers (Joy et al. 2015; Yu et al. 2006). The electrical quality factor (Q-factor) is one of the most important parameters in microelectronics engineering. It shows a relation between power stored and loss of power in the resonant circuit (Shantanu Dixit et al. 2017). It is referred to as the rate of energy stored to the energy loss per cycle in the resonator. It is in contradiction to the tangential loss (tan δ). The lower the dielectric loss the higher the Q-factor and vice versa (Heinola et al. 2004; Morarescu et al. 2016). The basic difference between the Q-factor and tan δ is that the Q-factor represents the efficiency of the capacitor whereas the tangential loss is the dissipation of the stored electri
