Overview

This approach strengthens hydrogels with fluorescent micelles, improving tensile strength and enabling recyclable anti-counterfeiting features.

Key Points

  • To develop tough photoswitchable fluorescent hydrogels for information encryption and anti-counterfeiting.
  • Utilized photoswitchable fluorescent micelles to enhance hydrogel properties.
  • Combined fluorogen BTPEBT and spiropyran-containing copolymers for micelle preparation.
  • Fabricated hydrogels using poly(vinyl alcohol) and freeze-casting techniques.
  • Achieved high toughness of 65.68 MJ/m³ and tensile strength of 15.42 MPa.
  • PFHs showed reversibly photoswitchable fluorescence and excellent mechanical performance.
  • Demonstrated potential for integrating various fluorescent nanomaterials into tough hydrogels.
