A microencapsulated linseed oil adhesive based on photosensitive indication: a smart material for visualized curing monitoring

Key Points

• The aim is to develop a microencapsulated adhesive that allows for visual monitoring of the curing process.
• Developed a core-shell adhesive using biomass-derived materials.
• Incorporated a photochromic indicator for real-time monitoring.
• Designed a pressure-responsive architecture for adjustable adhesion.
• The adhesive effectively changes color to signal curing progress.
• Demonstrated controllable adhesion properties upon application of pressure.
• Enabled on-demand release of the adhesive with visual feedback.
