The effect of PVAc solution viscosity on diameter of PVAc nanofibres prepared by technology of electrospinning

Popis výsledku v původním jazyce

Polyvinyl acetate (PVAc) nanofibers were prepared by technology of electrospinning with help of multi-jets electrospinning machine from acetic acid/water solvent system. The stability of the process was tested in a broad concentration region from 5 to 40wt. % of PVAc. The main attention was carried out to study the effect of polyvinyl acetate solution concentration/viscosity onto mean diameter of prepared nanofibers. It was found that increased solution viscosity leads to increase of fibers diameters from appox. 60 nm at viscosity ~ 0.04 Pa.s to appox. 1000 nm at viscosity ~ 6-7 Pa.s. The PVAc nanofibres can be considered as a potential precursor for preparation of inorganic fibrous nanoparticles. Their dimensions can be effectively controlled by PVAcnanofibers diameter by easy diameter - concentration/viscosity optimalization.
