The ionomer of sulfonated ethylene vinyl alcohol copolymers (EVOH-SO3K) crosslinked by toluene-2,4-diisocyanate (EVOH-SO3K) was synthesized and ionic polymer-metal composites (IPMC) based on EVOH-SO3K was produced through electroless deposition of argentum onto the surfaces of EVOH-SO3K membrane. FTIR spectroscopy confirmed sulfonic modification by introduction of two characteristic peaks at 1264cm-1...
In the present study, a new process for making non-woven membranes of polyimide (PI) using as insulation materials was described. The ODPA-ODA PI fibers are prepared by electrospinning a poly (amic acid) (PAA) solution, a precursor of polyimide, synthesized from 4,4'-oxydianiline (ODA) and 4,4'-oxydiphthalic anhydride (ODPA), followed by thermal imidization. The chemical structure, surface morphology,...
Polyimide nanofibers were obtained by electrospinning a solution of poly(amic acid)(PAA), a precursor of polyimide(PI) prepared in the laboratory, in dimethylacetamide(DMAc) at 14kV, followed by thermal imidization. Mechanical property of the resulting nanofiber non-woven membranes was investigated by tensile tests. Chemical structure and surface morphology of the non-woven mats were characterized...
