Reusable Polymer Waste Adhesives

Researchers at the Oak Ridge National Laboratory (ORNL) have developed a high-performance, reusable adhesive derived from waste polymers. This novel invention outperforms conventional glues in both wet and dry conditions.

Inspired by the adhesion mechanisms of mussels, the material incorporates reversible chemical crosslinkers that allow it to soften, detach, and be reused after curing—unlike traditional single-use adhesives. The formulation is capable of bonding a wide range of materials, including wood, glass, metal, paper, and plastics.

By combining durability with reusability across multiple applications, the innovation has the potential to streamline manufacturing and repair processes while reducing material waste.

"Most adhesives are made for one specific application," said Anisur Rahman, a research and development staff member at ORNL. "Our adhesive can be used for diverse applications, including structural or pressure-sensitive uses, and it performs reliably in both wet and dry environments," he said. "None of the commercial adhesives can be used this way."
