Paper Abstract

Poly (3-hexylthiophene)-tin dioxide (P3HT/SnO2) hybrid materials with different P3HT mass ratios were prepared by mechanical mixing. Composite films were prepared on QCM (Quartz Crystal Microbalance) by spin-coating. The films were characterized by UV-Vis spectrophotometer and SEM. The gas sensitive properties of this complex material to two series of organic vapors were investigated. The special groups in the thiophene ring were thought to be a sensory arm, which could be used to detect the target vapors. The sensitivity of the films on QCM increases with the molecule weight of alcohols and Cl-substitute methane. It is also increased with the concentration of organic vapors.
