New reversible glue offers alternative to electronics solder, solves e-waste issue

Newcastle University researchers developed a reversible conductive adhesive for electronics that can replace solder.

The glue is made from low-cost, scalable materials and conducts electricity like a strong electronic bond.

It can be dissolved on demand using alkaline solution or green solvents, making disassembly easier.

The approach could support reuse, recycling, and recovery of valuable materials while reducing e-waste.
