| Abstract Scope |
Degradable polymers and composites have found extensive applications in various industries but are currently limited to low-temperature usage due to their low glass transition temperature (typically <80°C). High Tg polymer composites, predominantly composed of epoxy resin, present challenges in decomposition, often necessitating high temperature, pressure, corrosive environments, and even supercritical fluids. The increasing adoption of fiber-enhanced composites for weight reduction and corrosion resistance further aggravates environmental concerns. This study addresses these challenges by introducing a pioneering solution in the form of a novel high Tg (>120°C) epoxy composite that exhibits water degradability below 90°C. The material development process and degradation mechanism will be comprehensively elucidated. To the best of our knowledge, this marks the industry's first water degradable high Tg epoxy composite, unlocking a plethora of new applications across industries and providing an environmentally friendly, green composite material. |
