Rutgers Team Programs Plastics to Self-Destruct on Cue

A Nature Chemistry study details a biomimetic design enabling on-demand deconstruction under everyday conditions.

Overview

  • Researchers embed conformationally preorganized neighboring groups that mimic natural polymers to speed internal bond cleavage.
  • Material lifetimes can be tuned from days to years, with breakdown built in or triggered by ultraviolet light, ambient sunlight, or metal ions.
  • The plastics retain strength during use and then deconstruct into small fragments without heat or harsh chemicals when activated.
  • Early tests found the breakdown liquid non-toxic, though full ecotoxicity, long-term safety, and activation in dark or buried settings remain open questions.
  • The team is assessing compatibility with existing plastics and manufacturing and is exploring applications from short-life packaging to timed drug delivery.
