Electrospinning - dependence of poly(ethylene oxide) mean nanofibre diameters on concentration and molecular weight
Popis výsledku v původním jazyce
The process of electrospinning was applied to solutions of poly(ethylene oxide) (PEO) in distilled water. An increase of mean nanofibre diameter with polymer molecular weight (4 different PEO) and polymer concentration (concentrations chosen with respect to spinnability) was expressed by a simple relationship quantifying this dependence within an experimental error. Further, another relationship was proposed for expressing shear viscosity of the entry polymer solution through corresponding molecular weight and concentration. The results show a possibility to prepare PEO nanofibrous mats with prescribed mean nanofibre diameter. The proposed relationship provides an instruction which PEO material and at which concentration should be chosen if we want to obtain a nanofibrous mat with the required nanofibre diameter. These results were obtained for PEO solutions in water, however, it is possible to expect that similar expressions could be derived for other materials.
