Preparation and characterization of UV-cured hybrid polyvinyl alcohol nanofiber membranes by electrospinning

The present study investigated the possibility of preparing polyvinyl alcoholic (PVA) organic-inorganic hybrid nanofiber membranes by electrospinning with UV irradiation. To this end, PVA, PVA/SiO sub(2) organic-inorganic hybrid obtained with Geniosil(R) XL 33 as a SiO sub(2) source, and imidazole-f...

Description
Summary:The present study investigated the possibility of preparing polyvinyl alcoholic (PVA) organic-inorganic hybrid nanofiber membranes by electrospinning with UV irradiation. To this end, PVA, PVA/SiO sub(2) organic-inorganic hybrid obtained with Geniosil(R) XL 33 as a SiO sub(2) source, and imidazole-functionalized mesoporous PVA/SiO sub(2)/N=N nanofiber membranes were synthesized. These membranes were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric-differential thermal analysis, and Brunauer - Emmett - Teller analysis. According to results, fine polymeric nanofibers were obtained in the size range of 100-200 nm for pure PVA nanofibers and 150-250 nm for PVA/Sio sub(2) hybrid nanofibers, while imidazole-functionalized PVA/SiO sub(2) nanofibers were less than 100 nm. The membranes produced are suitable for use in various applications, including filtration and adsorption, in the biomedical and textile industries, among others.
