Silicon carbide (SiC)-reinforced polythiophene (PTh) nanocomposites were synthesized by oxidative in-situ polymerization. The successful inclusion of SiC nanoparticles into the PTh was confirmed characteristic peak Si–C bond around 865 cm−1 in Fourier transform infrared (FT-IR) spectra. X-ray diffraction (XRD) patterns demonstrate that amorphous nature reduces with addition SiC. intensity UV–Vis absorbance increased proportionally filler loading, indicating improved optical properties for PThSiC7 (polythiophene/silicon carbide, 7 wt%) nanocomposite compared to pristine PTh. Field emission scanning electron microscopy (FE-SEM) images illustrate changes surface morphology and uniform dispersion observed PThSiC7. formation spherical-shaped moieties using transmission (TEM). shifts degradation glass transition temperatures towards higher values attributed enhanced thermal nanocomposites. Temperature-dependent studies on electrical dielectric samples underscored excellent conductivity exhibited (7 × 10−3 S/cm) a low activation energy 0.058 eV. In response growing demand gas sensors, tested sense ammonia gas, demonstrating PThSiC more sensitive than controllable properties, stability, characteristics, sensing performance suggest their potential as promising material development advanced storage systems, optoelectronic devices.
