| 英文摘要 | In this report, in contrast to conventional processes which rely upon non-covalent wrapping, we manipulate the covalent binding of conjugated polymers to carbon nanofibers to synthesize hybrid nanostructures. first, the friedel-crafts acylation reaction was utilized to introduce carboxyl groups onto the nanofiber sidewalls. octa-aminophenylsilsesquioxane was then uniformly covalently attached to the carboxylated nanocarbon (cnf-cooh) through amide linkage. subsequently, the phenylamino groups on the cnf surface were copolymerized with aniline via chemical oxidative polymerization to create a unique cnf-conjugated polymer hybrid (cnfs-pani), and a binder-free cnf-based composite paper electrode was generated by vacuum-filtration. morphology investigations revealed the formation of 3d porous interconnected network structures with loosely stacked hyperbranched pani nanobundles due to the incorporation of oasq onto the skeleton of cnfs. such a flexible cnfs-pani nanohybrid paper further exhibited excellent electric conductivity (0.31 s cm(-1)) and specific capacitance (167 f g(-1)), which is much higher than that of original cnfs (2.5 f g(-1)), suggesting its potential use as an electrochemical electrode material. |
