Simple table salt powers new sticky polymer technology
Graphical summary. Credit: Journal of the American Chemical Society (2024). DOI: 10.1021/jacs.4c06877 Adhesives are everywhere, from household tapes to adhesives in cars and electronic devices. Research into stronger, more accommodating adhesives is currently underway, but ultimately involves adding small amounts of salt to two special polymer components known as polyzwitterions (PZIs). It may be. New research by a FAMU-FSU School…
