Effect of electrospinning solution parameters on the properties of nonvolven fibrous material based on polyhydroxibutyrate

Abstract

Abstract In the present work, the influence of technological parameters of poly-3-hydroxybutyrate solution on the process of electrospinning of ultrathin fibers has been studied. It was established that the electrical conductivity and viscosity of the polymer solution largely determine the geometry and morphology of ultrathin fibers. Modification of solutions with ionic electrolyte and hydrolytic agent reduces the initial molecular weight of the polymer and leads to an increase in the viscosity of the system. It’s shown that the inputting of CNT leads to theorientation of the polymer macrochains in the amorphous phase. As a result, there are increases in mechanical, sorption properties and resistance to oxidative, thermal-oxidative and hydrolytic degradation. The fibers obtained will find application in biomedicine.
