英文摘要： Sensitive chemical- or bio-sensors can be used to effectively and early detect the environmental pollution, which is helpful for finding and resolving the environmental problems and hence has significant impacts on the environmental protection of our country. In this project, the high sensitivity of quartz crystal microbalance (QCM) and the diverse and versatile functionality of polymer thin film shall be combined to design and fabricate new chemical sensing device, which will be mainly applied in the detection of trace doxin and doxin-derivatives in the environments, or the trace organic amine in aqueous media. Functional polymer thin films, which possess unique sensitivity to the target pollutes, will be prepared. The interaction mechanism of the polymer thin films and the target pollutes will be systematically investigated by using QCM. The polymer thin films with optimal property shall be obtained, which will be used as sensing layers for the highly sensitive detection of trace doxin, trace doxin-derivatives, and trace organic amine, respectively. At the same time, efforts will be also paid to minimize the QCM and design portable chemical sensing device.
