• . Measurements of the interfacial contact angle were made on the as-fabricated amorphous membrane and after pore widening with a range of pore diameters from 25 to 100 nm. The possible applications of PAMs for various membrane technologies is shown. Keywords: interfacial contact angle; membranes; porous anodic

• the topological and technological characteristics on the resulting PAMs. The investigation of the wetting properties of PAM surfaces (outer and inner) was performed by measuring the interfacial contact angle (ICA). In our work, we show that with the control of morphology-dependent wettability of PAM

• ., PAM, nanochannel alumina NCA templates, Anodisc TM 25, Whatman Plc.) and domestically fabricated (in-house manufactured) PAMs. The degree of PAM hydrophilicity was determined by measuring the interfacial contact angle (ICA), θ, by the recumbent drop method [33]. To do this, a drop of distilled water
