“…After incorporation, an organic/inorganic nanocomposite was formed by blending the inorganic nanostructure of DDSQ with epoxy resin. The aim was to achieve a nano-reinforcement effect on the polymer by the inorganic nanostructure of DDSQ, to enhance the heat resistance and mechanical properties [ 53 , 54 , 55 , 56 ].…”

A series of di-functional benzoxazine (BZ) monomers was synthesized, specifically the double-decker silsesquioxane (DDSQ) cage structure (DDSQ-BZ). Comparative analyses were conducted between DDSQ-BZ monomers and the most commonly utilized bisphenol A-functionalized bifunctional benzoxazine (BPA-BZ) monomer. DDSQ-BZ compounds possess better thermal properties such as high char yield and high thermal decomposition temperature (Td10) after thermal ring-opening polymerization (ROP) because the inorganic DDSQ cage nanostructure features a nano-reinforcement effect. In addition, blending inorganic DDSQ-BZ compounds with epoxy resin was explored to form organic/inorganic hybrids with enhanced thermal and mechanical properties following thermal ROP. The improvement in mechanical properties is primarily attributed to the network structure formed by the cross-linking between DDSQ-BZ and the epoxy resin during thermal ROP, as well as hydrogen bonding interactions formed between the hydroxyl groups generated during thermal ROP and the Si-O-Si bonds in the DDSQ structure.

Plant oils are excellent renewable raw materials for thermosetting polymers, especially epoxy resins. The presence of double bonds, hydroxyl groups, and carboxyl groups in triglycerides allows for the attachment of some functional groups through chemical modification. Here we describe various chemical pathways for functionalizing triglycerides and fatty acids. Plant-oil-based epoxy resins exhibit the same excellent performance as petroleum-based epoxy resins, but burn easily, which limits their application in high-speed rail, aircraft, construction, and other fields. Therefore, imparting flame retardancy to vegetable-oil-based epoxy resins is very important. This chapter aims to summarize the most relevant and recent advances in intrinsically flame-retardant plant-oil-based epoxy resins. First, the synthesis method of a plant-oil-based flame retardant epoxy monomer is briefly introduced. Then special attention is paid to the flame retardancy, mechanical properties, and thermal stability of some plant-oil-based flame retardant epoxy resin thermosets of plant-oil-based epoxy monomers or curing agents. Finally, we briefly comment on the opportunities and challenges for the future development of plant-oil-based flame retardant epoxy thermosets.
