Electromagnetic interference (EMI) shielding materials with excellent flexibility and mechanical properties outstanding thermal conductivity have become a hot topic of research in functional composites. In this study, the “sol–gel-film conversion technique” is used to assemble polyetherimide-functionalized Ti3C2Tx nanosheets (f-Ti3C2Tx) poly(p-phenylene-2,6-benzobisoxazole) (PBO) nanofibers (PN...

The C O 2 / mixed-gas separation performance of a polyimide (Matrimid®), polyetherimide (PEI) and polylactic acid (PLA) membrane, were characterized in the presence - rich ternary ( ) quaternary N feed gas mixtures mimicking products reforming conversion reactions. membrane-based this mixture is poorly original data obtained novel mass spectrometric apparatus that permits to monitor instantaneo...

Integrally-skinned asymmetric Polyetherimide/Poly (vinyl alcohol) (PEI/PVA) hollow fber membranes for pervaporation dehydration were fabricated by non-solvent induced phase inversion. PVA inside the PEI matrix could be crosslinked to provide membrane performance stability during long term operation. The effects of different PEI/PVA blend ratio, external coagulant type and...

Mild steel (MS) coated with protective bilayer hybrid coatings of polyetherimide, and ZnO/CuO was exposed to artificial treated wastewater (ATWW) inoculated Desulfovibrio sp. (biotic system). Proteins from the extracellular polymeric substances (EPS) matrix responded coatings. PEI-CuO offered highest performance against biocorrosion. The higher resistivity value 2.17×10 6 Ω·cm 2 contrasted decr...

Copper hollow fibers were prepared via dry-wet spinning of a polymer solution N-methylpyrrolidone, Polyetherimide, Polyvinyl Pyrolidone, and copper particles sizes in the range 1–2 µm. To remove template molecules to sinter particles, time calcination was varied 1–4 h at 600 °C. This temperature determined based on Thermal Gravimetric Analysis (TGA), showing completion hydrocarbon removal this ...
