Synthesis, characterization, conductivity, and gas?sensing performance of copolymer nanocomposites based on copper alumina and poly(aniline? <i>co</i> ?pyrrole)

A series of copolymer nanocomposites based on poly(aniline-co-pyrrole) (PANI-co-PPy) with different contents copper alumina (Cu-Al2O3) nanoparticles were synthesized by benign in situ chemical oxidation polymerization. The structural, thermal transition, and morphological interpretations carried out Fourier-transform infrared spectroscopy (FTIR), x-ray diffraction (XRD), differential scanning calorimetry (DSC), high-resolution transmission electron microscope (HR-TEM). electrical properties such as alternating current (AC) conductivity dielectric measurements performed at room temperature to verify their application developing new electronic devices. presence the synergistic interaction matrix was confirmed FTIR XRD. HR-TEM indicates nanosized uniform dispersion nanofiller matrix. DSC revealed a reduction flexibility polymer an increase glass transition composites. AC measurement manifested increased hopping charge carriers when compared pristine PANI-co-PPy. Dielectric maximum for 5 wt% Cu-Al2O3. Excellent gas sensing traits observed due transfers existing between PANI-co-PPy ammonia gas. gas-sensing magnificent material make PANI-co-PPy/Cu-Al2O3 nanocomposites, promising contender nano-electronic
