For free-standing and self-doped electrode materials of energy storage devices, in this study, we investigate the microstructures and electrochem. properties of aromatic poly(ether amide) (PEA)-derived carbon nanofibers (CNFs), which are manufactured by electrospinning mixed solutions of PEA and poly(vinyl pyrrolidone) (PVP) at three different compositions and carbonization of the as-spun nanofibers at 1000°C. The SEM, energy dispersive spectroscopy, Raman spectroscopy, and elemental analyses reveal that PEA-derived CNFs have a unique interfused network structure with nitrogen self-doped and quasi-ordered graphitic features. Accordingly, a high apparent elec. conductivity of 3.72-7.79 S/cm is attained for the CNFs. The cyclic voltammetry and galvanostatic charge-discharge measurements confirm that PEA-derived CNFs have excellent electrochem. properties in terms of a specific capacitance of ∼249.0 F/g at 1.0 A/g, power d. of 10,000-1,000 W/kg, energy d. of 30.1-69.1 Wh/kg, capacitance retention of ∼79%, and Coulombic efficiency of ∼92% after 3000 cycle tests. These results indicate that PEA-derived CNFs can be used as highly stable, self-supporting, and doping-free electrode materials for high-performance energy storage devices. To complete the study, the researchers used 3-(4-Aminophenoxy)aniline (cas: 2657-87-6) .
3-(4-Aminophenoxy)aniline is one of ethers-buliding-blocks. Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. Related Products of 2657-87-6Ethers do have nonbonding electron pairs on their oxygen atoms, however, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds.
