A sulfonated diamine monomer, 4,4'-diaminodiphenyl ether-2,2'-disulfonic acid (ODADS), was successfully synthesized by direct sulfonation of a commercially available diamine, ether (ODA), using fuming sulfuric as the sulfonating reagent. series polyimides were prepared from 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTDA), ODADS, and common nonsulfonated diamines. The resulting displayed much better stability toward water than those derived widely used 2,2'-benzidinedisulfonic (BDSA)....
Although Ti3C2Tx MXene is a promising material for many applications such as catalysis, energy storage, electromagnetic interference shielding due to its metallic conductivity and high processability, it's poor resistance oxidation at temperatures makes application under harsh environments challenging. Here, we report an air-stable based composite with extracted bentonite (EB) nanosheets. In this case, oxygen molecules are shown be preferentially adsorbed on EB. The saturated adsorption of...
A new sulfonated diamine monomer, 9,9-bis(4-aminophenyl)fluorene-2,7-disulfonic acid (BAPFDS), was synthesized by direct sulfonation of the parent diamine, 9,9-bis(4-aminophenyl)fluorene (BAPF), using fuming sulfuric as sulfonating reagent. series polyimides with different degrees were prepared from 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTDA), BAPFDS, and common nonsulfonated diamines. The resulting generally showed good solubility in m-cresol DMSO. Proton conductivities these...
A series of wholly aromatic hyperbranched polyimides were successfully prepared by condensation polymerization a triamine monomer, tris(4-aminophenyl)amine (TAPA), and commercially available dianhydride monomers such as 2,2-bis(3,4-dicarboxyphenyl)hexafluoropropane (6FDA), 3,3',4,4'-diphenylsulfonetetracarboxylic (DSDA), pyromellitic anhydride (PMDA). The synthesis involves the formation polyamic acid precursors in first step thermal or chemical imidization subsequent step, which is similar...
Two novel sulfonated diamine isomers, 2,2′-bis(3-sulfopropoxy)benzidine (2,2′-BSPB) and 3,3′-bis(3-sulfopropoxy)benzidine (3,3′-BSPB), were successfully synthesized the highly polyimides (SPIs) with sulfonic acid groups in side chains prepared from 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTDA) BSPB monomers. Transmission electron microscopy (TEM) analysis revealed that these side-chain-type SPI membranes have a microphase-separated structure composed of hydrophilic chain domains...
Protic organic ionic plastic crystals (POIPCs) are shown to be novel anhydrous solid-state proton conductors for fuel cells.
Lithium-rich materials represented by xLi2MnO3·(1 – x)LiMO2 (M = Mn, Co, Ni) are attractive cathode for lithium-ion battery due to their high specific energy and low cost. However, some drawbacks of these such as poor cycle rate capability remain be addressed before applications. In this study, a thin polyimide (PI) layer is coated on the surface Li1.2Ni0.13Mn0.54Co0.13O2 (LNMCO) polyamic acid (PAA) precursor with subsequently thermal imidization process. X-ray diffraction (XRD), scanning...
MgH2 has become a hot spot in the research of hydrogen storage materials, due to its high theoretical capacity. However, poor kinetics and thermodynamic properties absorption desorption seriously hinder development this material. Ti-based materials can lead good effects terms reducing temperature desorption. MXene is novel two-dimensional transition metal carbide or carbonitride similar structure graphene. Ti3C2 one earliest most widely used MXenes. Single-layer only exist solution;...
The emerging field of graphene(GP)-based polymer nanocomposites has continued to be the focus considerable interest in recent years because unparalleled improvement shown mechanical, thermal, and electrical properties compared neat polymer. However, these improvements largely depend on synthesis well-exfoliated high-quality GP. In this paper, we report a facile method for production GP sheets through liquid-phase exfoliation graphite methanesulfonic acid (MSA). Raman, X-ray photoelectron...
A simple approach for the preparation of OPBI porous membranes by simply extracting PEG from dry OPBI/PEG blend membranes.
A facile approach has been successfully developed for the preparation of a series cross-linked sulfonated polyimide (SPI) membranes via condensation reaction between sulfonic acid groups and activated hydrogen atoms SPIs in presence phosphorous pentoxide : methanesulfonic ratio 1 10 by weight (PPMA, method 1) or only (method 2). The resulting sulfonyl linkages are very stable SPI showed greatly improved water stability comparison with uncross-linked ones while high proton conductivity was maintained.
