Аннотация

The paper presents the results of studying coatings based on poly(dimethylsiloxane) rubber crosslinked with MQ resin at different contents of the latter. The PDMS :MQ resin ratios have been taken to be 2 : 1, 1 : 1, and 1 : 2. It has been shown that the application of a hydrophobic fluorinated-group-free composite with composition PDMS :MQ = 1 : 1 onto a pre-textured surface by spin-coating or deep-coating results in the formation of superhydrophobic coatings. The coatings are characterized by extremely large contact angles (170°) and rolling angles no larger than 4°. The analysis of variations in the contact angle, surface tension, and contact diameter and volume of a water droplet that has been in contact with a coating for a long time has indicated a high hydrolytic resistance of the obtained coatings.
