Structure-Formation Features in Ultrathin Fibers of Poly(3-Hydroxybutyrate) Modified with Nanoparticles

Abstract

Supramolecular structure formation of poly(3-hydroxybutyrate) ultrathin fibers prepared by electrospinning and the influence of low concentrations of silicon and TiO₂ nanoparticles on the structure, physicomechanical and sorption properties, and resistance to thermal destruction and thermoand photo-oxidative destruction of non-woven fibrous material based on these fibers were studied. It was found that nanoparticles promoted the formation of thinner fibers with enhanced physicomechanical parameters and a structure that was more resistant to thermal and thermo- and photo-oxidative destruction and had a positive effect on the growth dynamics of mesenchymal stem cells.
