Volatile organic compounds (VOCs) sensors are the imperative technology of modern life for environmental monitoring. In this study, we demonstrated a VOCs sensor chip adopting the proposed methodology that the optical property of poly(3-hexylthiophene)(P3HT)/poly(methyl methacrylate)(PMMA) blend is sensitive to VOCs vapor due to morphological evolution and hence can be served as an indication of the presence of VOCs.[1] Various VOCs, including toluene, chlorobenzene and acetone, was used to test the sensitivity of our P3HT/PMMA VOCs sensing chip[2-3]. The P3HT/PMMA served as a representative blend, and the sensitivity of the P3HT/PMMA blend was optimized with respect to P3HT/PMMA blending ratio, and blend concentration. The low cost and high sensitivity VOCs sensing chip developed in this study significantly extends the current VOCs sensing technology and can be extensively used to effectively prevent humans and the environment from potential damages of VOCs.
