New Fibrillar Composites Based on Biodegradable Poly(3-hydroxybutyrate) and Polylactide Polyesters with High Selective Absorption of Oil from Water Medium

Ultrafine polyester fibers composed of poly(3-hydroxybutyrate), polylactide, and their various blends were obtained by electrospinning. The fibers were shown to have high absorption capacity towards oil, which is comparable with that of currently used absorbents. An advantage of the proposed systems is their biodegradability, which allows their subsequent disposal. In combination with moderate water absorption, the systems being developed can be considered as promising absorbents for crude oil and oil products from oil–water media in case of environmental accidents and water pollution.
