摘要

以蓖麻油为原料，用单质硫反硫化法制备了一种可再生的高硫多硫化物，并将其涂覆在棉织物上制备了超疏水过滤器。用3-氨基丙基三乙氧基硅烷（APTES）进行硅烷化，使织物与蓖麻油聚硫（CPS）涂层之间具有很强的附着力。所得的棉- cps过滤器的水接触角为155.3°，具有优异的拒水性。结构和表面表征采用FT-IR， HNMR， TGA, FE-SEM， EDS和x射线作图。该过滤器实现了水-石油混合物的重力分离，分离效率高（94 - 98%），渗透通量高达8067 L·m（⁻²·h）。值得注意的是，在10个重用周期之后，性能仍然保持稳定。这种绿色、可扩展的方法引入了生物基聚硫涂料的新应用，用于开发高性能、可回收的油水分离过滤器，与传统系统相比，它具有更高的效率和环境兼容性。

Green synthesis of castor oil-based polysulfide for recyclable Superhydrophobic filters in continuous and rapid water-petroleum separation

A renewable, high-sulfur-content polysulfide was synthesized via reverse vulcanization of elemental sulfur with castor oil and applied as a coating on cotton fabric to fabricate a superhydrophobic filter. Silanization with 3-aminopropyltriethoxysilane (APTES) enabled strong adhesion between the fabric and the castor oil polysulfide (CPS) coating. The resulting Cotton-CPS filter exhibited a water contact angle of 155.3°, demonstrating excellent water repellency. Structural and surface characterizations were performed using FT-IR, HNMR, TGA, FE-SEM, EDS, and X-ray mapping. The filter achieved gravity-driven separation of water–petroleum mixtures with high separation efficiencies (94–98 %) and permeation fluxes up to 8067 L·m⁻²·h⁻¹. Notably, performance remained stable after 10 reuse cycles. This green and scalable approach introduces a novel application of bio-based polysulfide coatings for developing high-performance, recyclable oil–water separation filters with superior efficiency and environmental compatibility compared to conventional systems.
