Overview

Innovative technology demonstrates reconfigurable information encryption in underwater environments, highlighting anti-counterfeiting potential.

Key Points

  • This research aims to develop slippery photoswitchable fluorescent coatings for underwater anti-counterfeiting and information encryption.
  • Integrated green fluorescent dyes and a photochromic spiropyran derivative into a slippery coating.
  • Utilized a polydimethylsiloxane (PDMS) base material via the Michael addition process.
  • Explored the photo-induced fluorescence resonance energy transfer (FRET) process for color switching.
  • SPFCs showed reversible fluorescence switching between green and red.
  • The coatings demonstrated excellent anti-fouling properties due to their oily composition.
  • Characterized by high contrast, fast photo-responsibility, and simple preparation process.
