Molecular anchoring of functional macromolecular compatibilizers – ANCHORS

Recycled plastics typically exhibit poor physical properties because they consist of blends of incompatible polymers with poor interfacial adhesion. Although many approaches have been reported to strengthen such interfaces, all suffer from drawbacks in terms of performance, cost-effectiveness, or modularity. In this research program, I will explore unconventional strategies to mechanically interlock incompatible semi-crystalline polymers together. The key innovation will be compatibilizers that feature molecular anchors, which are functional groups that are designed to become mechanically trapped in targeted crystalline phases. This project is oriented at improving the properties of polyolefin blends, but these principles will be applicable to semi-crystalline polymers in general. We envision that this strategy will also unlock new methods for surface functionalization and adhesion.
