© Published under licence by IOP Publishing Ltd.Borosiloxane materials (BS) with self-healing properties based on polydimethyl-siloxane with terminal hydroxyl groups and boric acid were obtained. BS was obtained with differ in viscoelastic characteristics by varying the synthesis conditions and composition. The properties of the obtained BS are characterized by the methods of synchronous thermal analysis and mass spectrometry. Self-healing and elastic properties were characterized by methods of spreading and rebound of ball from BS. The molecular and supramolecular structures of borosiloxanes obtained under various conditions explaining the difference in their viscoelastic properties are presented. It is shown that by changing the conditions of synthesis and the introduction of a plasticizer, it is possible to vary the parameters of self-healing and elastic properties of materials based on BS. The resulting materials may be interesting for various fields where the restoration of material characteristics by self-healing is required, from medical biocompatible materials to nano- and microelectronics and space technology.
