【摘要】 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。更多还原

【Abstract】 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.更多还原
