Selective separations and hydrodynamic studies: a new approach using molecularly imprinted nanosphere composite membranes
... based separation has been developed by coating molecularly imprinted nanoparticles onto the surface of a membrane disc whereby a selective composite membrane shall be realized. The imprints at the surface of the nanoparticles are comparable to footprints of specific molecules. These molecule ...

Hydrolysis differences of polyacrylonitrile support membrane and its influences on polyacrylonitrile-based membrane performance
... or 2 N KOH for 1 h at 65°C. Subsequently, the polyethyleneimine (PEI) was deposited on the top surface of the hydrolyzed PAN membrane to form a composite membrane. The pervaporation performance and ions rejection property of the PAN/PEI composite membrane clearly demonstrated that the hydrolysi ...

Synthesis of hyperbranched copolyimides and their application as selective layers in composite membranes
... were significantly higher for 6FDA-TAPOB [α(H2/CH4) = 228, α(O2/N2) = 6.4] than for 6FDA-6FpDA-TAPOB [α(H2/CH4) = 112, α(O2/N2) = 5.9]. Novel composite membranes based on these hyperbranched (co)polyimides (applied as selective layer) were successfully prepared. Preparation was made by di ...

Two types of membranes, the sulfonated PEEK-WC (poly(oxa-p-phenylene-3,3-phthalido-p-phenylene-oxyphenylene) (SPWC) and Krytox-Si-Nafion® (KSiN) composite membranes are proposed for DMFC applications. The properties based on water uptake, ion exchange capacity, proton conductivity, gas permeability ...
