Abstract:

In this study nanofibres were manufactured from bicomponent PVA/cationic starch (CS) polymers solutions using the electrospinning method. The effect of the starch derivative solution preparation procedure and weight ratio of bicomponent polymer solution on the morphology of nanofibres was investigated. Three types of polymer solutions were prepared: PVA/CS and PVA/homogenizated (hCS), both in water, and PVA/hCS in a mixture of ethanol/water. It was found that the homogenisation procedure for CS improves the spinability of the bicomponent solution. The use of ethanol in the solution allows to form nanofibres, even from one consisting of 25% hCS. It was estimated that a solution composition of PVA/hCS (85/15w/w) in a mixture of ethanol/water is optimal to produce nanofibers by electrospinning. Analysing the morphology of webs formed, it was estimated that more stick nanofibres were formed from the PVA/hCS solution than from the PVA/CS one. The use of a ethanol/water mixture in PVA/hCS causes the formation of thicker nanofibres.
