AP01009 Influence of Methyl Orange Dye Doping on Structural and Dielectric Behavior of Polystyrene

Abstract

This study examines how the structural and electrical characteristics of polystyrene (PS) are affected by varying methyl orange dye concentrations. The heat-press technique was used to create samples with different dye ratios (0%, 5%, 10%, and 15%). X-ray diffraction (XRD) was used for structural research, and an LCR meter was used to look at electrical characteristics. According to the findings, PS kept its polycrystalline structure, and when the dye ratio rose, so did the crystallinity. More dye concentration also resulted in higher electrical conductivity at high frequencies, indicating improved charge transfer. Furthermore, at low frequencies, the real and imaginary dielectric constants rose, whereas at higher frequencies, they decreased. These results suggest that PS is a potential material for electronic and dielectric applications as doping it with methyl orange enhances its structural ordering and electrical performance.
