Bridging polymer architecture, printability, and properties by digital light processing of block copolycarbonates.

ABSTRACT: CO₂-based aliphatic polycarbonates (aPCs), produced through the alternating copolymerization of epoxides with CO₂, present an appealing option for sustainable polymeric materials owing to their renewable feedstock and degradable characteristics. An ongoing challenge in working with aPCs is modifying their mechanical properties to meet specific demands. Herein, we report that monomer ratio and polymer architecture of aPCs impact not only printability by digital light processing (DLP) additive manufacturing, but also dictate the thermomechanical and degradation properties of the printed objects. We found that block copolymers exhibit tailorable thermomechanical properties ranging from soft elastomeric to strong and brittle as the proportion of hard blocks increases, whe
