APPLICATIONS OF TECHNOLOGY:
- New materials development, e.g., polymers, resins, adhesives, foams
- Low-cost, sustainable material platform
- Superior recyclability
- Low volatile organic compounds (VOCs)
- Tunable mechanical and transport properties (thermal, electrical, mass, charge)
The recycling of plastics is key to a sustainable materials economy with minimal environmental impact. Unfortunately, today’s plastics are not recycled to any appreciable extent, as the incentive to do so is low. This is due to the low value of recovered plastic materials as well as the cost and energy intensity of the processes needed. Brett Helms and Peter Christensen of Berkeley Lab have invented a new class of polymers that have performance attributes of polymers in use today with new opportunities to recycle them using low-cost and scalable chemical processes.
The Berkeley Lab invention advances and applies new dynamic covalent bonding strategies to synthesize high-performance polymers that can be de-polymerized to regenerate pure monomer in a true cradle-to-cradle process. Furthermore, the platform allows for broad formulation opportunities to suit both manufacturing and use needs.
DEVELOPMENT STAGE: Proven principle.
