英文摘要: Gragphene oxide (GO), as a tunable platform for gas sensing applications, can form a supermolecular composites with conducting polymer exhibiting high sensitivity, selectivity and single molecule detection performance.This project focuses on Langmuir-Blodgett (LB) assembly and vapor phase polymerization (VPP)deposition of GO/multi-composition conducting polymer supermolecular compoistes and its gas sensing performance.We will demonstrate the combination of this supermolecular composites with micro/nano gas sensor preparation technology to construct high performance gas sensors. The influence of conducting polymer composition in supermolecular composites on gas sensing performance,such as sensitivity and selectivity, is to be studied in detail. Moreover, the influence of GO reduction and doping state of conducting polymer on gas sening performance of supermolecuar composites will be also investigated. We explore the gas sensing mechanism and establish related gas sensing model for further understanding this nanomaterials as sensing materials. Hereby,based on the reserch above, we provide experimental and theoritcal basis to employ this novel supermolecular composites as excellent gas sensing materials for related high performance gas sensors.
