Abstract Hydrophobic poly(ether ether ketone) (PEEK) were modified by sulfonation at different temperatures (22, 36, 45, and 55°C) varying period of time with concentrated sulfuric acid used as solvent. A kinetic study was carried out based on the assumption that reaction is a second‐order reaction, which takes place preferentially in aromatic ring between two (O) links (the first type substitution), there only one substituent attached to each repeat unit PEEK before complete substitution...
In this study, we report on a novel potential-responsive hybrid film system for heavy metal removal, which was composed of layered α-zirconium phosphate (α-ZrP) nanosheet and conducting polyaniline (PANI)-intercalated chain that functioned as proton pumping element. The proposed features quick responsive uptake/release rate about 10 times the adsorption/desorption with an open circuit. exhibited high electroactivity because acidic micro-environment nitrogen atoms in PANI chains due to...
Polymers with high permeability and strong size-sieving ability are needed for H2/CO2 separation at temperatures ranging from 100 to 300 °C enable an energy-efficient precombustion CO2 capture process. However, such polymers usually suffer a permeability/selectivity tradeoff, that is, tend exhibit weak thus low selectivity. Herein, we demonstrate carbonization of suitable polymer precursor (i.e., polybenzimidazole or PBI) generates microcavities (leading H2 permeability) ultramicroporous...
