Аннотация
Preparation of superhydrophobic conducting coatings based on silicone matrix and two types of carbon nanotubes, native and modified with alkyl groups, is described. The amount of carbon nanotubes per unit surface area was kept constant in all the samples, whereas the content of the polymer matrix was varied. The electrical conductivity, contact angle, and sliding angle were measured. The structure of the coatings was studied with an optical profilometer and a scanning electron microscope. The largest contact angle was 158.4° for the sample with 50 wt % content of native carbon nanotubes. For the samples with more than 20 wt % content of carbon nanotubes of both types, the sliding angle was less than 1°. Changes in the micro- and nanostructure of the coatings, observed with variation of the content of the polymer matrix in the samples, were studied. The relationship between the structural changes, on the one hand, and hydrophobic and water sliding properties of the conducting coatings, on the other hand, was demonstrated.
