This disclosure relates to an ultra-tough, high-strength... T g Furthermore, this study explores controllable degradable thermosetting
epoxy resins, their preparation methods, and applications, aiming to address the challenges of achieving both high rigidity and high
toughness in traditional
epoxy resins, as well as their non-degradability after molding. Specifically, it employs
unsaturated hydrocarbon-terminated polysilsesquioxane JB-POS to modify the
epoxy resin. Through segmented crosslinking and
kinetic control, JB-POS undergoes in-situ self-
assembly within the
epoxy matrix to generate a uniform nano-core-shell structure. This structure forms the core of the material, achieving high rigidity, high
toughness, and high... T g The material exhibits a synergistic effect between performance and
structural stability. Furthermore, the dynamic ester and
silicon-
oxygen bonds within it endow it with on-demand and controllable degradation properties, achieving a synergistic balance between high
toughness, high
glass transition temperature, and controllable degradation performance. In addition, the preparation process disclosed herein is simple and can meet the needs of high-end fields such as
electronics and
aerospace, demonstrating promising prospects for industrial application.
