The invention discloses ferrocenyl blocked PU (polyurethane), a supercapacitor and a preparation method. The structural formula of the ferrocenyl blocked PU is shown in the description. The ferrocenylblocked PU has excellent redox characteristic and film-forming property, and a novel ferrocenyl pseudocapacitor is developed from the material. The pseudocapacitor is found to have specific capacitance up to 317.3 F.g<-1> when the current density is 2 A.g<-1> through cyclic voltammetry, constant-current charge and discharge and other electrochemical characteristics; in a Fc3-PU-Fc3 cycle life test under 50 A.g<-1>, the specific capacitance is attenuated by 12.4% after 3,000 times of cycles, which indicates that Fc3-PU-Fc3 is a good pseudocapacitor cathode material, and beneficial reference isprovided for developing novel pseudocapacitor cathode materials. 本发明公开二茂铁基封端型聚氨酯、超级电容器与制备方法，所述二茂铁基封端型聚氨酯的结构式如下式所示：其中，本发明提供的种二茂铁基封端型聚氨酯，具有极佳的氧化还原特性和成膜性，并利用该材料研制成种新型二茂铁基赝电容器。通过循环伏安法、恒流充放电等电化学表征，发现该赝电容器在电流密度为2A·g时，比电容高达317.3F·g；
