- Description:
- Interpenetrating polymer networks (IPNs) are multicomponent materials that enhance the compatibility of otherwise immiscible polymers by trapping the microstructure in a non-equilibrium state. By combining polymers with vastly different moduli, IPNs effectively disperse rigid polymers within a soft matrix, resulting in a reinforced elastomer. This approach significantly increases the modulus...

- Description:
- Conventionally cross-linked polymers, which comprise the vast majority of commercial thermosets, cannot be decross-linked after curing or flow upon heating. Therefore, they cannot be effectively recycled into high-value products at end-of-life. Their lack of recyclability is due to the permanent cross-links, which restrict the flow of the chains in the...
