Thermal conductivity of polyurethane sheets containing beryllium oxide nanofibers.

Polyvinyl alcohol/beryllium sulfate/polyethyleneimine (PVA/BeSO/PEI) precursor nanofibers (NFs) was first fabricated to obtain PVA/BeSO/PEI electrospun NFs by electrospinning technology, finally manufactured beryllium oxide (BeO) NFs followed by various heat treatment methods. The minimum calcination temperature for pure BeO NFs was 1000 °C, and the minimum specific surface area (5.1 m g) and pore volumes (0.

Structural analysis and dye removal behavior of amorphous titania embedded poly(vinyl butyral) hybrid fiber.

This study reports on the efficient methylene blue (MB) dye removal properties of a polyvinyl butyral (PVB)-amorphous titania (amTiO) hybrid fiber (PVB-amTiOF) made by air-gap spinning in acetone solvent. The successful fabrication of PVB-amTiOF was confirmed by employing Fourier transform infrared, scanning electron microscopy, X-ray photoelectron spectroscopy, thermogravimetric analysis, and energy dispersive X-ray measurement. Batch experiments were used to examine the cationic MB dye adsorption performance in the dark.
