Abstract

The preparation of nanostructures using porous anodic aluminium oxide (AAO) as templates involves the introduction of solved materials into the porous of the membranes; one way to determine which are the preferred materials to fill the pores, involves the measuring of the contact angle ([]) of different solvents or test liquids on the AAOs; thus, herein we present the results of the measurements of contact angles of nine solvents on four different AAO sheets by tensiometric and goniometric methods. From the solvents tested, we found dimethyl sulfoxide (DMSO), and N, N'-dimethyl formamide (DMF) to interact with the AAOs, being the polarity of the solvents and the surfaces the driving force.
