摘要
A new route for the manufacturing of silica/poly(benzimidazole) (PBI) nanocomposites fibers is described. PBI was synthesized via melt polycondensation and polycondensation in poly(phosphoric acid). Solutions of PBI and silica nanoparticles in N,N-dimethylacetamide (DMAc) were electrospun to fibers and non-wovens. The resulting materials were analyzed by ATR-IR spectroscopy, small-angle X-ray scattering (SAXS) and nitrogen sorption measurements. The non-wovens could be processed towards dense, cross-linked membranes by hot pressing and treatment with p-xylylene dichloride.
