摘要
用阳极氧化法可以在不添加氧化剂和不使用发烟硝酸的情况下,将NO_3^-插入石墨纤维中,降低石墨纤维的电阻率.本文考察了在65％的HNO_3中阳极氧化插层和反向通电过程中,PAN石墨纤维电阻率的变化,从而证实了石墨纤维阳极氧化插层后反向通电覆镀金属的可能性.
Under no adding oxidant and no using fuming nitric acid, nitric acid can be intercalated into graphite fiber by anodic oxidation method, thus the electrie resistivity of the graphite fiber will be decreased. The electric resistivity change of the graphitiged PAN carbon fiber hag been investigated by using the anodic oxidation intercalationin and counter reaction after the anodic oxidation intercalation in 65 % nitric acid. The probability was confirmed that intercalated graphite fiber was electroplated metal by counter reaction after anodic oxidation intercalation.
