Aniline (ANI), which refers to a monomer, has been used for in situ chemical polymerization to produce polyaniline (PANI) and titanium oxide (TiO2) composite. PANI was varied in composition of 20, 30, and 40 wt% loading with TiO2. Inclusion of PANI in composite is meant to detect acetone at various concentrations (100�500�ppm) at selected operating temperatures (27, 35, 45, 55, and 65��C). The results signified that the best structure of PANI loading in TiO2 is at 30 wt% due to the molecular structure for gas sensor. The sensitivity of PANI�TiO2 composite pellet for various acetone vapor concentrations had been optimum at 300�ppm with 7.9% sensitivity. The optimum operating temperature was 45��C with 10.12% sensitivity. Structural characterizations via X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, and Brunauer�Emmet�Teller were conducted to correlate with the sensor sensing performance. Indeed, the 30 wt% of PANI�TiO2 composite has the potential to detect 300�ppm of acetone and displayed exceptional agreement with outcomes retrieved at 45��C detection temperature. � 2019, Springer Science+Business Media, LLC, part of Springer Nature.
