摘要
本文综述了近年来应用于化学传感器中的聚合物的作用及种类,将其归纳为基质、载体,敏感试剂,气体透过膜三种作用;并且讨论了敏感试剂在聚合物上的固定化方法,包括吸附、交联、包埋和共价结合等。展现了聚合物在化学传感器中的应用前景。
Functions and varieties of various polymeric materials in chemical sensors which can be used as carrier and mediator, sensitive agents, gas permeating membranes have been presented. The advantages of using polymeric materials are listed: enforcing stability, increasing sensitivity, short response time, no-polluting to analyte, continuously detecting, and lower cost. The immobilization methods of reactive agents including adsorption, cross linking, entrapment and covalent fixation are also discussed. Application trend of polymeric materials for chemical sensors is outlined.
