This study proposes a cellulose-based monolithic Janus-like membrane prepared by non-solvent-induced phase separation (NIPS) from cellulose acetate followed by alkaline deacetylation and unilateral silanization (TEOS\/MTES). The resulting membrane exhibits asymmetric wettability (hydrophobic: 91\u00b0, hydrophilic: ~0\u00b0). Structural and chemical characterization (SEM, EDS, FTIR, and BET\/BJH) confirms the formation of a siloxane-containing surface layer, the integrity of the cellulose network, and a distribution of the pores toward the nanoscale, with a specific surface area of 26.9 m\n                    <jats:sup>2<\/jats:sup>\n                    \/g.
