神经毒剂由于呈现氢键碱性,因此以氢键酸性物质作敏感材料可以提高传感器的灵敏度、增强选择性、缩短响应时间。综述了氢键酸性敏感材料的研究现状,结果表明超支碳硅聚合物与线形、超支碳硅氧烷聚合物相比具有响应幅度大、工作温度高、抗干扰性强等优点。
Nerve agents present hydrogen-bond basicity, therefore, higher sensitivity, better selectivity and faster response for nerve agent detection can be achieved by employing hydrogen-bond acidic (HBA) polymers as sensitive layers. In this paper, the research progress of HBA polymers in recent years are reviewed. It shows that carbon-silane hyperbranched polymers possess larger amplitude response, higher working temperature and better selectivity when compared with linear and hyperbranched carbon-siloxane polymers.
