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.

基于可生物降解的聚（3-羟基丁酸酯）和聚丙交酯聚酯的新型原纤维复合材料，具有从水介质中高选择性吸收油的能力

由聚（3-羟基丁酸酯）、聚丙交酯及其各种共混物组成的超细聚酯纤维是通过静电纺丝获得的。这些纤维被证明对油具有很高的吸收能力，这与目前使用的吸收剂相当。所提出的系统的一个优点是它们的生物降解性，这允许它们随后的处理。结合适度吸水，正在开发的系统可以被认为是在发生环境事故和水污染的情况下从油水介质中提取原油和石油产品的有前途的吸收剂。
