This study introduces smart fabrics using aggregation-induced emission (AIE) dyes for sensing applications. These recycled fabrics offer tunable fluorescence for detecting temperature, humidity, and volatile organic solvents (VOCs).
Area of Science:
- Materials Science
- Textile Engineering
- Chemical Sensing
Background:
- Textile-based sensors offer a flexible and wearable platform for environmental monitoring.
- Aggregation-induced emission (AIE) dyes provide unique fluorescence properties sensitive to molecular aggregation state.
Purpose of the Study:
- To develop a novel textile-based adsorption sensor using AIE dyes on recycled fabrics.
- To investigate the impact of mixed solvent dyeing on fabric fluorescence and sensing capabilities.
- To explore the thermochromic and vaporchromic properties of the developed smart fabrics.
Main Methods:
- Incorporation of AIE dyes into recycled fabrics via a mixed solvent dyeing method (H2O and organic solvents).
- Tuning the water fraction in the co-solvent mixture to control dye aggregation and fluorescence.
- Characterization of fluorescence properties, thermochromic, and vaporchromic responses.
Main Results:
- Successfully developed textile-based sensors with tunable fluorescence properties based on AIE dye aggregation.
- Demonstrated reactive thermochromic and vaporchromic behavior in response to temperature and volatile organic solvents (VOCs).
- Achieved repetitive fluorescence switching and resistance to photo-bleaching, indicating practical applicability.
Conclusions:
- Mixed solvent dyeing with AIE dyes on recycled fabrics is a viable method for creating advanced smart textiles.
- These smart fabrics exhibit significant potential for applications in fashion, clothing, and environmental sensing (temperature, humidity, VOCs).
- The developed sensor technology offers a sustainable and versatile approach to wearable sensing solutions.
