摘要
在硫酸介质中，以氧化铟锡（IT0）透明导电玻璃为载体，利用循环伏安法制备3-氨基苯硼酸-苯胺共聚物膜，研究了该薄膜对维生素C（AA）的光学响应。结果表明，利用电聚合方法可在ITO玻璃表面形成均匀致密的蓝色3-氨基苯硼酸-苯胺共聚物薄膜，薄膜的厚度可通过控制电位循环圈数来进行调节，薄膜使用后可用恒电位法和循环伏安法进行再生；在3％RAc介质中，在2．0—17．5mg·L-1范围内薄膜对从浓度的变化产生灵敏的光学响应，且在480-750nm波长范围内随着波长的增加响应的灵敏度增加。
Thin films of copolymers of 3-aminophenylboronic acid- aniline were deposited on Indium Tin Oxides （ITO） coated glass by cyclic vohammetric method in sulfuric acid. The optical response of the copolymer film against ascorbic acid（AA） was studied. The results showed： uniform dense blue films of 3-Aminophenylborenic Acid-Aniline were formed on ITO, with changeable thickness being controlled by potential-current cycles. The regeneration of the film could be made by potentiostatic technique and cyclic voltammetry. The film showed very high optical sensing when the concentration of AA changed from 2.0 to 17. 5mg · L^-1. The film response sensitivity against AA concentration increased with increasing wave lengthen from 480nm to 750nm.
