Advanced Epoxy with Dynamic Bonds #worldresearchawards #researcher #epoxyresins
Epoxy resins are widely used in coatings, adhesives, composites, and structural applications due to their excellent mechanical strength, chemical resistance, and thermal stability. However, conventional epoxies are permanently crosslinked, making them brittle, difficult to repair, and nearly impossible to recycle. The introduction of dynamic disulfide bonds is transforming epoxy systems by overcoming these long-standing limitations. Dynamic disulfide bonds are reversible covalent linkages that can break and reform under external stimuli such as heat, light, or mechanical stress. When incorporated into epoxy networks, these bonds enable bond exchange reactions without compromising the overall crosslinked structure. As a result, epoxy materials gain remarkable new functionalities while retaining their inherent strength and durability. One of the most significant advantages of disulfide-based epoxy systems is self-healing. Microcracks generated during service can autonomously repair whe...
