Preparation and properties of PAN nanofiber membrane based on spiral spinning technology

The PAN spinning solution was chosen as the spiral research object. Laminar flow theory used to straighten and align macromolecules, needles were control twisting of straightened macromolecules. internal arrangement nanofibers became more compact helix number increased. TEM (transmission electron microscope) photograph motion trajectory TiO 2 (titanium dioxide) nanoparticles in nanofibers, which directly confirmed feasibility principle. SEM (Scanning Electronic Microscopy) observations revealed that appearance nanofiber membranes changed some extent under physical technology. analysis tensile bursting properties demonstrated structure significantly after spinning. pore structure, electrical resistance, antibacterial membrane all reached optimal values at needle.
