On rheological behaviour of PVB solutions in the process of electrospinning

Original language description

Described is suitability of various polyvinylbutyral (PVB) solutions for the process of electrospinning in which, under a strong electrostatic field, fibres are created and deposited on a template. The 6, 10, and 14 wt% PVB solutions were prepared with the following four solvents: methanol, ethanol, isopropanol, and butanol. A rotational rheometer equipped with the electrorheological cell (bob and cup arrangement, diameter of 17 mm), and a scanning electron microscope were used to compare the electrorheological behaviour of the materials studied and their potential for use in the process of electrospinning. It was proved that an application of better solvents of PVB implies worse quality of an electrospun material and vice versa. This is documented bybehaviour of a curve expressing dependence of the ratio of shear viscosities in presence and absence of an electric field on a shear rate.
