A team led by researchers at the University of Washington developed a new PCB that performs on par with traditional materials and can be recycled repeatedly with negligible material loss. Researchers used a solvent that transforms a type of vitrimer — a cutting-edge class of polymer — into a jelly-like substance without damage, allowing solid components to be plucked out for reuse or recycling. Here, from left to right is a vitrimer-based circuit board, a sheet of glass fibers, vitrimer that’s been swollen and removed from a board, and electrical components such as a computer chip.
