PET is used in many commercial products, but only a fraction is mechanically recycled, and even less is chemically recycled.
This work presents a novel method for upcycling polyethylene terephthalate (PET) waste into sustainable vitrimer materials. By combining bio-based crosslinkers with our PET-based macromonomer, we developed dynamically bonded plastics that are renewably sourced.
This invention focuses on improving the ceramic yield of preceramic polymers by tuning the crosslinking process that occurs during vat photopolymerization (VP).
The incorporation of low embodied carbon building materials in the enclosure is increasing the fuel load for fire, increasing the demand for fire/flame retardants.
Most plastic is discarded after a single use, with about 76 percent of plastic waste discarded into landfills annually. The current practice is wasting feedstock resources, energy, and carbon used for their production.
ORNL’s mixed plastic recycling technology can simultaneously break down any condensation polymers—PET, polycarbonate, polyurethanes, and polyamides—into monomers in a low-energy green process.
Adhesive and sealant materials are crucial in construction, automotive, and electronics industries. However, most adhesives fail under stress or environmental conditions like dust, water, or wear.
A novel approach was applied for the preparation of polymer membranes having CO2-philic group for CO2 separation.
