Superhydrophilic properties of aluminum oxide nanofibers

Abstract

The article considers structural properties of aluminum oxide nanofibers with superhydrophilic properties obtained
in oxalic acid by single-stage electrochemical anodizing, whose structure differs from that of nanoporous aluminum oxide. The superhydrophilic properties of the obtained nanofibres were determined using an Ossila contact angle goniometer. It has been found that the duration of the anodisation process affects not only the nanostructure of the anodic oxide, but also the hydrophilic properties. The studies have shown that the contact angle of the nanofibres formed at 60 seconds of anodisation process decreases
to 4.37 ◦ for 10 seconds and exhibits a superhydrophilic property.
