Article Synopsis
- The study focuses on creating molecularly imprinted polymers (MIPs) for enhancing detection of specific aromatic hydrocarbons like benzene, toluene, and xylene isomers.
- MIPs are synthesized using methyl acrylate as a monomer, toluene as a template, and ethylene glycol dimethacrylate as a cross-linking agent, with various characterization techniques employed to analyze their properties.
- Results show that the MIPs exhibit high sensitivity and selectivity for detecting these hydrocarbons, and their effectiveness is significantly influenced by the ratios of the components used in their preparation.
In this work, a quartz crystal microbalance (QCM)-based adsorption sensor system with high sensitivity, selectivity, and reproducibility is designed and fabricated. The functional polymers such as polypyrrole, poly(3,4-ethylenedioxythiophene) (PEDOT), and polystyrene are coated on 8 MHz AT-cut quartz crystal surfaces as sensing materials for SO2 and NO2. All sensing materials on the QCM surface are characterized experimentally by SEM and AFM.
