Metal-organic frameworks (MOFs), as newly emerging filler materials for polyelectrolytes, show many compelling intrinsic features, such variable structural designability and modifiability of proton conductivity. In this manuscript, UiO-66-NH2, a stable MOF with -NH2 functional groups in its ligands, was selected to achieve high-performance sulfonated poly(arylene ether nitrile)s (SPENs)/UiO-66-NH2-x covalent-ionically cross-linked composite membrane. Simultaneously, the obtained membranes...
In order to investigate the effect of crosslinking degree on water uptake, swelling ratio, and methanol permeability sulfonated poly(aryl ether nitrile)s (SPENs), molar content group in bisphenol monomer is fixed at 60% this work. The properties poly (aryl nitrile) with different degrees are studied by changing propenyl nitrile)s. cross-linking reaction groups SPENs cured 230 °C. All results show that method an effective way improve meet application requirements membranes as proton exchange...
Metal-organic frameworks (MOFs) have been widely investigated for their porosity and functional diversity. Inspired by the flexible designability of MOFs, UiO-66-NH 2 /CNT with moniliform nanostructure was designed synthesized successfully. SPEN@UiO-66-NH composite proton exchange membranes were prepared loaded into sulfonated polyarylene ether nitrile (SPEN). Due to addition /CNT, all properties improved. The exhibit excellent thermal stability dimensional stability. tensile strength...
Abstract Present polymer inhibitors depend on a major inhibitory group to restrain bentonite hydration, and monomer design is concerned improve the inhibition stability through complex copolymerization. Conveniently, homopolymer (PIL‐NH 2 ) that contained primary amine cationic imidazolium as bi‐functional groups was proposed, aiming provide two synergistic modes. Comprehensive methods were conducted characterize chemical structure performance of PIL‐NH . The ζ potential absolute value...
In recent years, forest fires have occurred frequently, and relying on helicopter to extinguish is an important means of fire prevention. The rapid determination demand after a can not only save time for dispatching helicopters, but also improve rescue efficiency. order effectively predict the number helicopters needed in fires, forecasting model based index fuzzy segmentation (IFS) TOPSIS proposed. view nature reliability level has usually been overlooked past research, IFS was constructed...
It is important for regenerative fuel cells, rechargeable metal–air batteries and water splitting to find reasonable designed nonprecious metal catalysts, which have efficient durable electrocatalytic activities oxygen reduction reaction (ORR), evolution (OER) hydrogen (HER). In this work, through a simple hydrothermal method following annealing process, Mo 2 C Ni nanoparticles were encapsulated in nanoporous hierarchical structure of carbon (Ni/Mo C/C). The ingenious delivers several...
Sulfonated polyaryl ether nitrile (SPEN) is some of the most viable novel materials to replace Nafion membrane. To resolve issue proton conductivity in fuel cells with poor sulfonation degree cell membranes. A metal-organic structure (MOF-801) was added as a filler, and imidazole loaded by MOF-801 structural skeleton via chemical ligand improve SPEN’s conductivity. The expected im-MOF-801 SPEN@Im-MOF-801 confirmed using FTIR 1 H NMR. Loading into SPEN resulted composite exchange impacts...
After an earthquake, a timely and rapid emergency response is important prerequisite for improving the efficiency of relief reducing earthquake disaster losses. The prediction material demand not only foundation in post-earthquake areas, but also one key problems that need to be solved urgently at present. Considering lack information area, model predicting supplies case unclear area constructed. Firstly, rational simplification historical database carried out using principal component...
