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.
