Extreme impact enhancement of epoxy using a sulfosuccinate-based anionic surfactant as a new modifier

Type: article
Abstract: In this study, disodium lauryl ether sulfosuccinate (DSL or sulfosuccinate), a commercially available anionic surfactant, was employed for the first time as an impact modifier for epoxy resin. Introducing only 5 phr of DLS into the epoxy matrix resulted in a remarkable 189% enhancement in impact strength without a significant detrimental effect on its tensile strength. According to FTIR and SEM results, the strong interaction between the modifier DLS and the epoxy matrix, along with the formation of a nano-blend morphology with a wide interfacial area, can be proposed as two key factors contributing to the remarkable enhancement in impact strength of epoxy/DLS hybrid. The thermal stability of the epoxy was not significantly affected by the incorporation of DLS up to 8 phr. The epoxy/DLS hybrid exhibited lower chemical stability against organic solvents, while the hybrid resistance to acids and bases remained largely unchanged. Based on the obtained results, DLS can be considered as a promising impact modifier for epoxy systems.
