Investigators from National Institute of Technology Target Chemical Engineering

January 29, 2014



By a News Reporter-Staff News Editor at Journal of Engineering -- Current study results on Chemical Engineering have been published. According to news reporting out of Andhra Pradesh, India, by VerticalNews editors, research stated, "Polythiophene (PTP) coated SnO2 nano-hybrid particles have been synthesized using an ultrasound assisted in situ oxidative polymerization of thiophene monomers. Reference experiments have also been performed in the absence of ultrasound to clearly illustrate the effect of ultrasonic irradiations."

Our news journalists obtained a quote from the research from the National Institute of Technology, "FTIR results show broadening and shifting of peaks toward lower wave numbers, suggesting better conjugation and chemical interactions between PIP and SnO2 particles. Due to strong synergetic interaction between the SnO2 nanoparticles and polythiophene, this hybrid nanocomposite has the potential application as chemical sensors. It has been observed that PTP/SnO2 hybrid sensors could detect liquefied petroleum gas (LPG) with high sensitivity at room temperature. PTP/SnO2 hybrid composite containing 20 wt%SnO2 showed the maximum sensitivity at room temperature."

According to the news editors, the research concluded: "The sensing mechanism of PTP/SnO2 hybrid nanocomposites to LPG was mainly attributed to the effects of p-n heterojunction between PIP and SnO2."
