Abstract

Currently, the study of the phenomenon of superhydrophobicity has made very significant advances, one of which is the obtaining of superhydrophobic coatings based on composite materials in order to improve the properties of some materials, such as: corrosion inhibitors, the reduction of the adherence of liquids on the surface in these materials. Since some anticorrosive coatings are really expensive, including the manipulation of the technique. With the application of nanotechnology there has been greater progress, this is due to the excellent methods for obtaining coating with anti-corrosive and superhydrophobic properties. In the present article, a superhydrophobic composite based on nano particles of kaolin - recycled polymers is presented, with innovative application as a coating, presenting anticorrosive and non-moisture properties; for low carbon steels, the composite was deposited with a Cartesian robot with spray deposition, and therefore homogeneous coatings with expected characteristics were obtained. Fourier Transform Infrared Spectroscopy (FTIR) indicates the presence of the functional groups Ac. Carboxylic (COOH) at 2920 and 2853 cm-1, characteristic of highly hydrophobic surfaces. In addition, approximation methods were applied to measure the contact angle (Reflection and Image Magnification), which showed that the angle is equal to or close to 150º. Corrosion tests with chambers simulating corrosive atmospheres were carried out, favourable results were obtained, which shows that the nanostructured composite has anti-corrosive and superhydrophobic properties.
