The atomic layer deposition method is employed to grow metal oxide and metallic three-dimensional nanostructures using porous alumina membranes [41], electrostatically spun nanofibers [39][40] or electrosprayed spherical particles [38] as templates.

It was found that increasing the volume fraction of DCM leads to an increasing amount of fibrillar polymer structures within the porous ALOX-membrane. A three

The high surface area and high mechanical stability of such materials allows for applications in

Results and Discussion Topological features of porous alumina membranes In the process of manufacturing of a PAM, the obtained membranes were analyzed after each main stage by means of SEM and AFM. Altogether several types of samples were prepared with different

• . Wetting properties of porous alumina membranes The previously presented results show that the topological features of PAM surfaces can differ substantially depending on through-pores obtaining. Therefore, the contact (wetting) angle was determined on the outer and back sides of the membrane. Schematically
