Acid gases such as SOx, NOx and CO2 are typical air pollutants released into the atmosphere by combustion in factories and automobiles.In this studies, QCM sensor which was coated by molecular imprinted polymer(MIP). Piezoelectric devices coated by MIP film which formed specific cavities originated by functional monomer, amino-compounds groups as the crosslinker and radical initiators. The QCM coating surface was investigated by using scanning electron microscope(SEM) and atomic force microscopy(AFM). The oscillation frequencies variation by NO2 gas adsorption was measured and evaluated an adsorption characteristic of the QCM surface. |
