摘要
In order to easily achieve the multifunctionality of epoxy resin, this paper designs and synthesizes a ternary hybrid copolymer containing POSS/DOPO/F. This method not only facile combines POSS with DOPO, but also introduces F element to further reduce the surface energy of epoxy composite materials. Research has found that the POSS/DOPO/F ternary hybrid copolymer can achieve a UL-94 flame retardant rating of V-0 with just 5 wt% of the modifier, and the limit oxygen index of epoxy composites is 32% (23.1% higher than pure epoxy resin). The residual char after combustion is denser and the carbonization rate is higher. Furthermore, we conducted an in-depth analysis of the flame retardant mechanism of POSS/DOPO/F ternary hybrid copolymer epoxy composites using TGA-FTIR technology and EDS. In addition, the introduction of ternary hybrid polymers effectively improves the mechanical properties of epoxy composite materials and significantly reduces the surface energy of the composite materials.
