To tackle the global recycling problem of thermosets, a novel class of reprocessable cross-linked polymer materials has been developed, i.e. covalent adaptable networks (CANs). However, most of the reported CANs are not viable for industrial applications since their production relies on expensive chemicals or because they exhibit inferior properties compared to common thermoset resins. The aim of this research proposal is to obtain robust CANs by exploiting the potential for dynamic exchange of carbonates, starting from widely available, low-cost chemicals. Rational design of monomers, starting from epoxides and CO2, will allow us to introduce alcohols as neighbouring groups that are capable of reversible ring-closing reactions with carbonates. To fully understand the dynamic behaviour of the proposed chemistry platform, a rheological study will first be performed on a series of model networks. The obtained results will subsequently be used as entry point to introduce dynamic carbonate moieties into the industrially relevant epoxy matrix to facilitate recycling at elevated temperatures. In a next step, this project aims to develop self-blowing dynamic polycarbonate foams as a sustainable alternative to the widely used polyurethane foams. This will be achieved through the controlled hydrolysis of cyclic carbonate monomers, thereby releasing CO2 as blowing agent. The obtained foams will finally be subjected to thermal recycling tests.
