Conventional thermoset materials cannot be remolded and recycled due to the covalent bonds existing in the network. The reversible nature of secondary interactions between monomeric units renders supramolecular structure reconfigurable abilities upon exposure to appropriate stimuli. This feature is quite useful in the design of novel thermoset materials with remoldability and recyclability, but its widespread adoption is limited due to the low strength and high cost of supramolecular structure. Here, we present a new class of thermoset with a distinct recycling mechanism and structural design. It is strong, transparent, recyclable, 100% biorenewable, creep resistance after thermal treatment, and produced in a ultrafast, scalable and cost-effective manner. These characteristics come from a purpose-designed hybrid network via a ultraviolet radiation in seconds. This technology provides a new way to obtain thermosets with remoldability and recyclability. It is green and efficient, not limited in lab, and can be scaled up for industry.
