有机电导体一直是当前人们感兴趣的课题。人们已经认识到掺杂是制备导电聚合物的一个重要过程。掺杂是一种电荷转移反应，在许多情况下已经用化学方法实现了。也有研究表明，掺杂是用电化学方法实现的，如对乙炔、pol（吡咯）、酞菁聚硅氧烷或聚n -乙烯基咔唑9。本文报道了一种简单的将绝缘聚合物电化学掺杂转化为导电聚合物的方法，即电化学沉积（ECD）法，它的特点，以及在聚乙烯二茂铁上得到的结果。据我们所知，本研究提出了用电化学方法制备导电的部分氧化聚二茂铁的第一个例子。研究了聚乙烯二茂铁8、9的伏安法，以及聚乙烯二茂铁修饰电极的方法。有报道称，聚乙烯二茂铁在二氯甲烷中氧化时的循环伏安表现出一个峰值畸变，这是由于被氧化物的强吸附引起的。本文用电化学方法制备了聚乙烯二茂铁包覆铂电极，并研究了这种表面修饰电极的电化学性能。本文提出的将绝缘聚合物转化为导电聚合物的电化学掺杂方法就是在这些工作的基础上发展起来的。
Organic electrical conductors have been the subject of current interest. It has been recognized that doping is an important process for the preparation of electrically conducting polymers. The doping, which is a charge-transfer reaction, has been achieved chemically in many It has also been shown that doping is achieved electrochemically3-~, as found for, eg, p~ lyacetylene~), pol~(pyrrole)~), phthalocyaninatopolysiloxane6), or poly (N-vinylcarbazole) 9. This paper reports on a simple technique for the electrochemical doping of insulating polymers to transform them into conducting polymers, which is termed here electrochemical deposition (ECD) method, its characteristic features, and the results obtained for poly (viny1ferrocene). To the best of our knowledge, the present study presents the first example of the preparation of an electrically conducting, partially oxidized poly (viny1ferrocene) by electrochemical methods. The voltammetry of poly (viny1ferrocene) 8, 9, and the electrode modification using poly (viny1ferrocene) have been studied. It has been reported that the cyclic voltammogram for the oxidation of poly (viny1ferrocene) in dichloromethane exhibits a peak distortion, and that this is caused by strong adsorption of the oxidized have prepared a poly (viny1-ferrocene)-coated platinum electrode electrochemically and studied the electrochemical properties of this surface-modified electrode. The present method for the electrochemical doping that transforms insulating polymers into conducting polymers is based on these works.
