Bilayer films between thermoset epoxy and thermoplastic poly vinylpyrrolidone) (PVP) were prepared by casting a stoichiometric mixture of the uncured diglycidyl ether of bisphenol A epoxy (DGEBA) and 4,4′-diaminodiphenylsulfone (DDS) on a PVP film and then curing the system in a two-step process under an inert gas atmosphere.
Integral asymmetric membranes for gas separation were prepared by casting a poly ether imide) solution in tetrahydrofuran (THF) and gamma-butyrolactone (GBL) and coagulating in water.
He added, "That would tell me that it is a poly-ether foam, which is a lower grade foam that is a flammable material".
The system consisted of a Poly-Ether-Ether-Ketone (PEEK) chipholder with a heater, and a glass chip, surrounded by air.
Briefly, a blend of 15% poly methyl vinyl ether- alt-maleic acid) (PMVE/MA) and 7.5% poly ethylene glycol) (PEG) was cast onto a poly(dimethylsiloxane) (PDMS) microneedle mold and filled into the mold cavities under vacuum (see the Supporting Information).
In this study, nanocomposite blend membrane comprised of the sulfonated poly (ether ether ketone) (SPEEK), sulfonated poly (vinilidinfluoride-co-hexaflourpropylen) (SPVDF-co-HFP) and lanthanum chromite (LaCrO3) was successfully prepared by the solvent casting method.
Poly(BSMS-b-ProHEMA) yielded a tough membrane by casting from its toluene solution.
Blends of poly p-phenylenebenzo[1,2-d:5,4-d′]bisoxazole) (poly p-phenylenebenzo[1,2-dr ether ketone) (poly p-phenylenebenzo[1,2-d casting and coagulating methanesulfonic acid (MSA) solutions containing different fractions of each polymer.
Multilayered polyelectrolyte complexes (PECs) which applied as methanol barrier agents are prepared by alternate deposition of the oppositely charged amino-containing poly (ether ether ketone) (Am-PEEK) and the highly sulfonated SPAEK-C via a layer-by-layer method.
Facile solution casting was then used to develop blend membranes comprised of sulfonated poly (ether ether ketone) (SPEEK).
Novel anhydrous proton exchange membrane is (PEM) facilely prepared by embedding dopamine-modified silica nanoparticles (DSiOis2) into sulfonated poly (ether ether ketone) (SPEEK) polymer matrix.
