Rheological Characterization of Polymer Solutions with Respect to Quality of Electrospinning Process

Anotace

Nowadays, nanofibrous layers are intensively studied for their unique properties and potential applications. For instance medical applications like tissue engineering use fibres as a carrier of the cells. The advantage of the nanofibrous layers is a high specific surface area together with high porosity and fibre diameters reaching at most hundreds of nanometres. There are many production processes of nanofibres to which we can include an electrostatic spinning from polymer solutions or melts. If a polymer solution is exposed to external high voltage evoking electrostatic forces, the fibres are emitted from the surface layer of polymer solution and finally collected in drawing state.
