This study investigates the incorporation of ionic liquid 1-(hydroxyethyl)-3-methylimidazolium hydrogen sulfate ([EtOHMIM+][HSO4−]) into polystyrene (PS) to enhance its dielectric and thermal properties. The structural integration within PS matrix was confirmed by 1H 13C NMR, FTIR, Raman spectroscopy, which revealed molecular-level interactions successful doping PS. Thermal analysis via differential scanning calorimetry (DSC) showed significant shifts in properties post-doping, including a reduction glass transition temperature new transitions, indicative increased molecular mobility flexibility. Dielectric were evaluated across range temperatures frequencies. PS-IL composite exhibited considerable increase constant with temperature, especially at frequencies above 1 kHz, peaking around melting liquid. enhancement is attributed conduction facilitated [EtOHMIM+][HSO4−], introduces additional charge carriers polarizable sites. loss further indicated energy dissipation mechanisms associated dipolar relaxation elevated temperatures. Electrical conductivity measurements demonstrated thermally activated behavior composite, due doped matrix. findings indicate that [EtOHMIM+][HSO4−] significantly improves characteristics, positioning as promising candidate for applications requiring high performance tunable conductivity, such storage electronic devices. research provides insights liquid-polymer interactions, advancing design functional polymeric materials tailored electrical
