“…The XPS spectrum of N 1s was deconvoluted into two peaks with the binding energies centered at about 397.34 and 399.98 eV. The peak at the lowest binding energy at 397.34 eV can be attributed to the carbon atoms from the aromatic ring bonded with the imine type of nitrogen atoms whereas the highest energy contribution at 399.98 eV may be attributed to sp 2 carbon atoms bonded to NH 2 groups [27].…”

“…Prepared mesoporous carbons such as Su-OMC and N-OMC showed fast charge-discharge responses at the beginning of both positive and negative sweeps. It has been accepted that when the ions are more easily accessible to the electrochemically active surface, the charge-discharge characteristics are faster, even at a high voltage sweep rate [27], which is important for reversibility of electrochemical capacitors. It is believed that the pore structures of mesoporous carbons, which have large pore sizes with a narrow pore-size distribution, favor ionic penetration into pores and thereby lead to the fast chargedischarge characteristics found for OMC and N-OMC [11][12][13].…”

In this work, the electrical double-layer capacitive properties of nitrogen-doped ordered mesoporous carbons (N-OMCs) were investigated. Ordered mesoporous carbons (OMCs) with 3D body-centered Ia3d structure has been prepared by KIT-6 mesoporous silica as a hard template with aniline for N-OMC and sucrose for Su-OMC as a carbon precursor. Using the different carbon precursor, moderate amounts of nitrogen atoms could be doped to the OMC structures. The obtained materials were characterized by powder X-ray diffraction (XRD), nitrogen adsorption isotherms at 77 K, elemental analysis, and X-ray photoelectron spectroscopy (XPS). Prepared OMCs had mesopore properties such as a high surface area with narrow pore-size distribution. From cyclic voltammograms (CVs) test, N-OMC compared to Su-OMC exhibit higher capacitance and fast charge/discharge characteristics, which results from their pseudo-capacitive effect of incorporated nitrogen atoms. It was thought that N-OMC prepared by the nanotemplating method with KIT-6 and aniline were suitable electrode materials for electrical double-layer capacitors.

“…14,15 However, these methods tend to be detrimental to the intrinsic properties of PI films. 16 Besides, generally, there are complicated procedures involved in these methods. Relatively, heat-sealing technique is a facile method for bonding films, which needs just a thermal-pressing step followed by a cooling procedure.…”

Intrinsically heat-sealable polyimides with atomic oxygen (AO) resistance (ARPIs) were synthesized from 2,3,3′,4′-oxydiphthalic anhydride (aODPA), 2,5-bis[(4-aminophenoxy)phenyl]diphenylphosphine oxide (BADPO), and para-phenylenediamine (PDA). The effects of the molecular structure and diamine ratio were investigated on the properties of the ARPI, including mechanical property, thermal property, heat sealability, and AO resistance. Heat sealability and AO resistance were realized for the ARPI film by combining the asymmetry of the aODPA moiety and the passivated layer forming characteristic of diphenylphosphine phosphine oxide group. Meanwhile, the deficiency of low mechanical strength and thermal resistance, commonly existing in a completely BADPO-derived polyimide system, was remedied effectively by the higher reactivity and rigidity of PDA.

“…To overcome this nonadhesive obstacle, much efforts have been made, including physical or chemical surface treatments 11,12 and surface coating with additional polymers (polytetrafluoroethylene, acrylic resin, etc.). 13,14 However, these methods tend to endow PIs with good adhesiveness at the expense of their intrinsic properties, 15 such as the deterioration of mechanical strength or thermal stability, due to the surface damage or the inferior thermal resistance of coating materials. Besides, generally, there are complicated procedures involved in these methods.…”

A series of polyimides (PIs) with good heat sealability were synthesized from an asymmetric aromatic dianhydride, 2,3,3 0 ,4 0 -oxydiphthalic anhydride, and aromatic ether diamines with different structures featured by ether amounts, substituted positions of ether linkages, and substituted positions of amino groups. In detail, the effects of these three substructures in the diamine were investigated on thermal resistance, thermoplasticity, and heat sealability of the PI film. It is found that the glass transition temperatures and heat-sealing strengths of the prepared PI films are influenced to different extents by the variations of the substructures, because of their different contributions to the chain mobility. These PI films are demonstrated to possess good heat sealability evidenced by completely fused heat-sealing interfaces and high heat-sealing strengths up to 580 N m À1 .
