Properties of polyurethane fibrous materials produced by solution blow spinning

Vol. 41, nr 4

267–-276

The study aimed to produce nano- and microfibrous materials from polyurethane (ChronoFlex®C75A/ C75D in 1,1,1,3,3,3–hexafluoro–2–propanol) by solution blow spinning. Experiments were carried out in order to determine the impact of solution blow spinning parameters on fibre diameter and quality of produced materials. The following properties of produced fibre scaffolds were investigated: fibre size, porosity and pore size, wettability, and mechanical properties. The results confirmed that produced nano- and microfibrous materials could be potentially used as scaffolds in three-dimensional cell and tissue cultures.
