Oil spills are a common occurrence that threatens marine life, necessitating sustainable remediation methods. Polyvinylidene fluoride (PVDF) membranes known for their hydrophobicity, chemical resistance, and thermal stability, but they hindered by naturally low porosity due to the high-density polymer structure. To address this limitation, porous with synergistic properties was required. In study, kapok (Ceiba pentandra) fibers, which possess high porosity, were acetylated improve stability then blended PVDF. The development of oil-absorbing PVDF/CTA membrane aligns Sustainable Development Goal 14: Life Below Water. kapok-derived CTA characterized confirm its degree substitution (2.9) solubility in non-polar solvents. Converting fiber into improved combination crystalline amorphous regions provided balance between flexibility structural integrity. molecular conformation verified 1H-NMR 13C-NMR. Incorporating PVDF significantly increased 16%, enhancing oil absorption capacity. Only 1.828 m2 PC3 membrane, compared 2.656 PC0, required absorb 1 kg crude oil. findings study strongly indicate producing can overcome limitations neat membranes. membrane's surface area could be further maximized incorporating it cassette-style flow cell membrane. High-porosity thus have potential an efficient solution spill environments.
