Ladder-like Poly(methacryloxypropyl) silsesquioxane-Al₂O₃-polybutadiene Flexible Nanocomposites with High Thermal Conductivity.

ABSTRACT: Ladder-like poly(methacryloxypropyl)-silsesquioxanes (LPMASQ) are photocurable Si-based gels characterized by a double-stranded structure that ensures superior thermal stability and mechanical properties than common organic polymers. In this work, these attractive features were exploited to produce, in combination with alumina nanoparticles (NPs), both unmodified and functionalized with methacryloxypropyl-trimethoxysilane (MPTMS), LPMASQ/Al₂O₃ composites displaying remarkable thermal conductivity. Additionally, we combined LPMASQ with polybutadiene (PB) to produce hybrid nanocomposites with the addition of functionalized Al₂O₃ NPs. The materials underwent thermal stability, structural, and morphological evaluations via thermogravimetric analysis
