In the context of accelerated industrial growth, a multifaceted array of challenges and opportunities is emerging, with oil-water separation emerging as a particularly pressing problem that demands urgent attention. In recent years, considerable effort has been dedicated by researchers to address this dilemma. However, existing methods for achieving oil-water separation have consistently fallen short of expectations. This work utilizes the cellulose present in wood to fabricate a regenerated cellulose wood membrane. The pore structure is then reinforced using polyvinyl alcohol (PVA) and tannic acid (TA), forming the PVA/TA@regenerated cellulose wood membrane. The membrane exhibits hydrophilicity and underwater superoleophobic properties; and can enhance stability and improve separation efficiency. The resulting membrane displays exceptional separation performance, achieving a separation flux of 2823 L·m−2·h−1 with a separation efficiency of 99.8 %. This work provides a new method of fabricating a rough wood template offers an innovative strategy for producing superhydrophilic/underwater superoleophobic membranes, which show great potential for applications in oil/water separation.
