Abstract
In this work, a superhydrophobic polymer with hierarchical porous structure is firstly used as novel Quartz crystal microbalance (QCM) sensing material for toluene detection. Superhydrophobic property, porous structure, and rich aromatic ring composition of the polymer make its stable toluene/water selectively detection performance. The sensor exhibits good sensitivity for toluene detection. The response remain stable at different ambient humidity. The detection limit reaches down to 1 ppm, and the selectivity is satisfactory to twelve kinds of common interfering gases. This superhydrophobic porous polymer functionalized QCM sensor may be a potential candidate for the future application of toluene detection.
