Dynamic thiourea networks enable self-healing chromic films for visual detection of light and acidic vapors

Key Points

• The central aim is to develop chromic films that can both self-heal and detect environmental changes like light and acidic vapors.
• Utilized dynamic thiourea networks for film production
• Assessed response to varying light conditions and acid exposure
• Evaluated self-healing capabilities after damage
• The films showed effective detection of light and acidic vapors
• Self-healing properties were confirmed after material damage
• Demonstrated potential applications in environmental monitoring
