Superhydrophobic and superoleophilic graphene/polyvinylidene fluoride (G/PVDF) aerogels were prepared by solvothermal reduction of the graphene oxide PVDF mixed dispersions. The chemical component was verified FT-IR, XRD, XPS, Raman spectroscopy TGA. as-prepared aerogel showed high specific surface area, eminent absorption capacity for oils organic solvents, superior water repelling ability, excellent recyclability, considerable mechanical properties. Therefore, this kind is a promising...
A superhydrophobic neat graphene aerogel that exhibited excellent properties for oil-absorption and oil–water separation has been fabricated the first time.
Graphene oxide was reduced by natural gallic acid at room temperature and upon heating. Gallic functioned as both a reductant stabilizer during the reaction. The reduction of graphene verified UV-vis, IR, Raman spectroscopy XPS. Moreover, (rGO) exhibited best dispersibility ever reported in water organic solvents because stabilizer. For example, rGO synthesized is up to 1.2 mg ml−1 4 dimethylsulfoxide, respectively. This study offers green approach mass preparation with excellent dispersibility.
A superhydrophobic graphene-based foam with outstanding elasticity was prepared for the first time, indicating excellent application prospects.
We propose a facile synthesis approach for nitrogen doped porous carbon and demonstrate novel pore-forming method that iron nanoclusters act as template or activator at different carbonization temperatures based on Fe3+-poly(4-vinyipyridine) (P4VP) coordination. P4VP will completely decompose even in an inert atmosphere, but under the coordination catalysis of Fe3+, it can be converted to very low temperature (400 °C). The aggregation process showed methods temperatures. as-prepared...
Sulfonated polybenzothiazoles (sPBT) with high molecular weight as well excellent solubility were synthesized for the first time, which was achieved by attaching phenylsulfonyl pendant groups or incorporating hexafluoroisopropylidene moieties to polymer backbone. Such sulfonated thus could be cast into homogeneous membranes and further evaluated proton exchange membranes. These sPBTs showed thermal stability conductivity low swelling. For instance, hexafluoroisopropylidene-containing sPBT a...
Sulfonated poly(arylene ether sulfone)s with phosphine oxide moieties (sPESPO) were achieved by polycondensation of bis(4-hydroxyphenyl)phenylphosphine 3,3′-disulfonate-4,4′-difluorodiphenyl sulfone (SFDPS) and 4-fluorophenyl (FPSF). (sPES) also synthesized polymerization 4,4′-sulfonyldiphenol SFDPS FPSF for comparison. The comparative study demonstrates that the sPESPO ionomers exhibit strong intermolecular interactions high oxidative stability because groups. Furthermore, membrane sPES an...
Abstract A series of sulfonated poly(phthalazinone ether phosphine oxide)s (sPPEPO) were prepared via aromatic nucleophilic substitution polycondensation 4‐(4‐hydroxyphenyl) phthalazinone (HPPZ) with bis(4‐fluorophenyl)phenyl oxide (sBFPPO) and (BFPPO) at various ratios. The properties such as molecular weight, ion exchange capacity (IEC), swelling, thermal stability, proton conductivity, morphology investigated. sPPEPO high IEC exhibited conductivity while they still showed low swelling....
This work investigated the thermal treatment of sulfonated poly(arylene ether phosphine oxide) membranes under vacuum without using any cross-linking agents or additives. During treatment, sulfonic acid groups acted as cross-linkable and reacted with activated benzene rings in membranes, resulting self-cross-linking. Interestingly, available degree almost no longer increased increasing time temperature after required because many could not be cross-linked due to steric hindrance only...
The fabrication of high-performance metal-free carbon catalysts for the oxygen reduction reaction (ORR) is practical importance energy sector. A novel strategy was used to prepare N,S-codoped mesoporous carbons (NSMPCs) as ORR catalysts, involving preparation poly(3-aminothiophenol)-based assemblies followed by subsequent pyrolysis. N and S heteroatoms poly(3-aminothiophenol) are incorporated into NSMPCs pyrolysis, forming abundant catalytic active sites. mesopores locate on their surface,...
