Summary
Researchers developed smart textiles from polyaniline (PANI)/MXene/cotton fabrics (PMCFs) that offer tunable electromagnetic interference (EMI) shielding. These fabrics act as a switchable shield, responding to acid and alkali vapors for advanced applications.
Area of Science:
- Materials Science
- Nanotechnology
- Textile Engineering
Background:
- Two-dimensional transition-metal carbides (MXenes) and conductive polymers are used for electromagnetic interference (EMI) shielding composites.
- Acid/alkali-responsive EMI shielding textiles have not been previously reported.
Purpose of the Study:
- To fabricate electrically conductive polyaniline (PANI)/MXene/cotton fabrics (PMCFs) for acid/alkali-responsive and tunable EMI shielding.
- To investigate the responsive mechanism and shielding performance of the novel textile.
Main Methods:
- Vacuum filtration-assisted spray-coating method to deposit PANI/MXene onto cotton fabrics.
- Characterization of material structure, electrical conductivity, and EMI shielding efficiency.
- Testing the response to ammonia and acid/alkali vapors.
Main Results:
- The PMCF demonstrated a sensitive ammonia response (19.6% at 200 ppm).
- Optimized PMCF achieved a high EMI shielding efficiency of approximately 54 dB.
- The fabric exhibited switchable EMI shielding (24 dB to 15 dB) triggered by hydrogen chloride and ammonia vapors.
Conclusions:
- The developed PMCF offers tunable and responsive EMI shielding capabilities.
- This multifunctional fabric shows potential for intelligent garments and flexible electronic sensors in special environments.
- The study highlights a novel approach for smart textile development with adaptive electromagnetic properties.
