Effect of Glycero-(9,10-trioxolane)-trialeate Ozonide on Structure and Mechanical Properties of Ultrathin Polylactide Fibers Produced by Electrospinning.

Abstract—Nonwoven fibrous materials based on polylactide (PLA) and ozonide of oleic acid triglyceride (glycero-(9,10-trioxolane)-trialeate) in a range of concentrations of 1–5 wt % intended for hygienic and medical devices are obtained by electrospinning. The introduction of ozonide leads to plasticization of PLA, which manifests itself in the cleavage of the primary jet of the forming solution and appearance of ultrathin nanofibers; here, the porosity and relative elongation at break increase. The optimum weight fraction of ozonide introduced into PLA is determined to be 3 wt %. [ABSTRACT FROM AUTHOR]
