Název v původním jazyce

Gas sensing properties of polypyrrole/poly(N-vinylpyrrolidone) nanorods/nanotubes-coated quartz-crystal microbalance sensor

Popis výsledku v původním jazyce

A quartz-crystal microbalance (QCM) sensor coated with colloidal polypyrrole/poly(N-vinylpyrrolidone) (PPy/PVP) nanorods/nanotubes film was employed for the detection of alcohol vapors. Alternate lining layers of polyelectrolytes were assembled onto QCM electrode followed by subsequent addition of colloidal PPy/PVP to prepare nanorods/nanotubes film by a simple drop-casting method. The frequency changes of the QCM due to the adsorption of aliphatic alcohols vapors onto PPy/PVP nanorods/nanotubes films were determined as a function of their corresponding injected concentrations. Frequency change was found to correlate linearly with the concentrations of injected alcohol vapors. The sensor exhibited relatively fast response and good sensitivity for ethanol, 1-propanol and 1-butanol in the range of 35.7–184 mg L−1. The sensor showed good detection sensitivity towards alcohol vapors which would occur by dominant hydrogen bonding interaction with amino- and imino-like groups along the PPy chains. The adsorption kinetics of alcohols onto PPy/PVP nanorods/nanotubes film-coated QCM sensor was carefully studied.
