Production of Nanostructured Aluminosilicate Fibers from Poly(ethylene glycol) Based Electrospun Fibers

摘要

In this work, nanostructured aluminosilicate fibers are prepared by submit-ting poly(ethylene glycol) (PEG) electrospun fibers containing sol-gel derived aluminosilicate nanoparticles to a calcination treatment. The prepared materials are characterized by scanning electron microscopy (SEM), dynamic light scattering (DLS), infrared spectroscopy (FTIR), x-ray diffraction (XRD) and thermal analyses (DSC and TGA). The calcination of hybrid electrospun PEG fibers containing 20wt% of nanoparticles generated well-defined high-surface area aluminosilicate fibers containing residual carbon. The production of nanostructured aluminosilicate fibers displaying high porosity and residual carbon can improve the performance of catalysts and membranes.
