New reversible conductive glue could reshape electronics repair, recycling, and material recovery

A collaboration between electrical and chemical engineers at Newcastle University is responsible for a reversible glue that can change how we recycle electronic waste. The team has already demonstrated reversible adhesive technology with wide applicability in general packaging applications, but this new glue is electrically conductive. This means that it can join electronic components, just like solder does. Unlike solder, however, a simple wash with a green solvent like acetone, or using an alkaline solution, will allow the components to be separated for reuse or recycling.
