The growing demand for glass coatings underscores the need for multifunctional protective layers, as silica-based glasses are prone to brittle fractures. Our research focuses on developing a transparent, self-healing coating using organo-oligosiloxane materials. We construct the coating by crosslinking oligosiloxane nano resins, prepared via sol-gel chemistry, with Diels-Alder (DA) adducts known for their simplicity and self-healing efficiency. To ensure optical transparency, we synthesize non-phenyl Diels-Alder adducts. We investigate the effects of crosslinker lengths on self-healing efficiency and mechanical properties, and enhance scratch resistance by constructing an interpenetrating network. Furthermore, thermogravimetric analysis shows a high char yield over 600°C, indicating potential as a flame-retardant material due to the high silicon content.
