摘　　要：The biodegradable polymer demonstrates significant potential for addressing the critical environmental challenges associated with oil spills;however, the cellular film structure and hydrophobic characteristics of the polymer restrict their efficacy. In this study, a biodegradable thin membrane composed of a blend of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and poly(caprolactone) (PCL) was fabricated utilizing the electrospinning technique. The membrane exhibited an adsorption capacity for cooking oil of 10.8 g/g, and Fourier-transform infrared spectroscopy (FTIR) analysis confirmed the anticipated chemical structures, revealing no evidence of chemical interactions between PHBV and PCL. This research presents an environmentally friendly and straightforward approach for fabricating biodegradable membrane structure with exceptional oil-water separation capabilities.The biodegradable polymer demonstrates significant potential for addressing the critical environmental challenges associated with oil spills;however, the cellular film structure and hydrophobic characteristics of the polymer restrict their efficacy.
