Abstract Quasi‐2D layered organometal halide perovskites have recently emerged as promising candidates for solar cells, because of their intrinsic stability compared to 3D analogs. However, relatively low power conversion efficiency (PCE) limits the application 2D in photovoltaics, due large energy band gap, high exciton binding energy, and poor interlayer charge transport. Here, efficient water‐stable quasi‐2D perovskite cells with a peak PCE 18.20% by using 3‐bromobenzylammonium iodide are...
Hydrogels as fire-resistant materials have attracted great attention due to their high water content and tailored shapes that can cover various surfaces.
Three-dimensional (3D) perovskites have been demonstrated as an effective strategy to achieve efficient light-emitting diodes (LEDs) at high brightness. However, most 3D perovskite LEDs still suffer from serious efficiency roll-off. Here, using FAPbI3 a model system, we find that the main reason for droop and degradation in is defects ion migration under electrical stress. By introducing bifunctional-molecule 3-chlorobenzylamine additive into precursor solution, detrimental effects can be...
Fluorine/silicone composite rubber is widely used as a sealing material in aerospace, missile, automotive, petroleum, and other industries, but the traditional process does not use synergistic fillers to strengthen system. In this research, fumed SiO2 black caron (N990) were fillers, fluorine/silicone was prepared by mechanical mixing process, three different fluorine systems find best material. The properties, thermal aging moderate strength microstructure of composites evaluated. Studies...
Investigating the mass transfer of toluene methylation with methanol will contribute to converting more feedstock into para-methyl group. The reaction system was considered as three competing reactions: and isomerization para-xylene light hydrocarbons. When thiele modulus analysis method employed, degree utilization each calculated over varied ZSM-5 zeolite catalysts. It found that improvement leads a significant increase in reaction. And further reduce isomerization, modification micropore...
Abstract The application of traditional chemically crosslinked hydrogels is often limited by poor mechanical properties because their own inhomogeneous network and irreversible crosslinking bonds. Herein, physical interactions are applied to crosslink the interpenetrating hydrogel, i.e., hydrogen bonding crystalline domain for polyvinyl alcohol network, hydrophobic interaction inside micelle poly (acrylamide‐ co ‐stearyl methyl acrylate) [P(AAm‐ ‐SMA)] network. In this gel system, reversible...
The alkylation of benzene with methanol can effectively generate high-value-added toluene and xylene out surplus benzene, which is now achieved primarily using solid acids like H-ZSM-5 zeolites as catalysts. In this work, two samples distinct framework aluminum (AlF) distributions, but otherwise quite similar textural acidic properties, have been prepared by employing tetrapropylammonium hydroxide (TPAOH) n-butylamine (NBA) organic structure-directing agents (OSDAs). Systematical...
Abstract Hydrogels containing a large amount of water are widely used as fire‐resistant materials. However, when exposed to fire, the organic polymer network gel will burn in short time contained evaporates. For that, fire‐retarding ammonium polyphosphate (APP) and woven basalt fibers introduced polyacrylamide (PAAm) hydrogels improve performance. Thermo‐gravimetric tests indicating that APP can prevent from decomposition effectively content is larger than 13 wt%. And form foam layer on...
Abstract Hydrogels containing a large amount of water have been widely studied as fireproof materials. However, the organic networks that composed gel easily burns evaporates. In this work, used intumescent flame‐retardant ammonium polyphosphate was modified by carbon–carbon double bonds (abbreviated MAPP) and introduced in alginate/poly (acrylamide‐co‐stearyl methacrylate) [alginate/P(AAm‐ co ‐SMA)] hydrogel free radical polymerization. The resultant MAPP@alginate/P(AAm‐ ‐SMA) hydrogels...

In this work, a newly hydrogel‐based dressing is designed backing of expanded polytetrafluoroethylene (ePTFE) film. The ePTFE grafting polyvinylpyrrolidone (PVP) brush composited hydrogel successfully an adhesion energy ≈80 kJ m −2 . resultant composite, the contributes excellent breathability, water resistance, bacterial barrier property. vapor transmission rate composite 4.83...
A novel fluorine-containing water-repellent agent (OFAE-SA-BA) was designed and synthesized by emulsion copolymerization, which used to replace the commercial long fluorocarbon chain agent. To improve water repellency, intermediate monomer containing two short fluoroalkyl chains were successfully characterized 1H NMR, 13C NMR FT-IR, respectively. After being treated agent, surface chemical composition, molecular weight, thermal stability, morphology, wetting behavior, durability of modified...
Perfluoroalkyl substances (PFASs), such as perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic (PFOS), can contaminate the surface groundwater. Common treatment strategies adsorbents have low adsorption efficiencies poor selectivity toward PFASs because of extremely energy these compounds. This paper reports use a phenolic resin (PR) modified with perfluoroalkyl (PFA) segments thermally sensitive poly(ethylene glycol) (PEG) (PR-PEG–PFA) to remove PFOA PFOS from water. The PR...
AbstractA b-oriented MFI shell was formed on the ZSM-5 crystal by pretreating core using ammonia prior to hydrothermal synthesis in tetrapropyl ammonium hydroxide medium. The effect of surface structure material MFI/MFI zeolite investigated. Si-OH groups and amorphous aluminate may play an important role forming coating. composition changed from high-silica silicalite-1 after twice coating synthesis, while coverage increased 85% 99%. In toluene methylation, not only prevented deactivation...
Abstract Expanded polytetrafluoroethylene (ePTFE) has superior properties such as compression creep resistance and resilience, but it is difficult to bond with other materials due its low surface energy, high crystallinity highly symmetrical structure. In this paper, a new type of pressure‐sensitive adhesive prepared from butyl acrylate, glycidyl methacrylate unique pentafluorobenzyl in which pentafluorophenyl group introduced provide steric hindrance avoid clustering increase the affinity...
Membrane surface fouling is a key problem for water filtration. Compositing photocatalytic substances with base membrane widely used strategy, but most of the will be decomposed by photocatalysis. Herein, expanded polytetrafluoroethylene (ePTFE) extremely stable chemical properties grafted polyacrylic acid (PAA) and then modified titanium dioxide (TiO2) to realize self-cleaning TiO2-PAA-ePTFE filtration membrane. It can recover its flux under UV irradiation after fouling. With 20 rounds...
