Abstract
This research explores the electrical, molecular, and structural characteristics of PVC: PMMA Polyblend (1:2) doped with 8% salicylic acid. AC conductivities and dielectric constants were measured over a temperature range of 303 K to 353 K using a Precision LCR meter, revealing nuanced with dopant concentration, temperature, and frequency. FTIR spectroscopy highlighted distinct peak differences in PVC-PMMA films with and without the dopant, emphasizing the impact of salicylic acid on molecular interactions. XRD analysis demonstrated an amorphous nature in both doped and undoped thin films, while SEM and EDX revealed heterogeneous structures with varying dopant percentages. The study provides valuable insights into the intricate interplay between temperature, frequency, and dopant concentration in the electrical and structural properties of PVC: PMMA blends. These findings contribute to the understanding of material behavior for potential applications in diverse fields such as materials science and pharmaceuticals.
