Summary
Chestnut tannin (CT)-modified cotton fabrics show excellent formaldehyde (HCHO) adsorption. This cost-effective textile development offers promising applications for air purification in various environments.
Area of Science:
- Materials Science
- Textile Chemistry
- Environmental Science
Background:
- Formaldehyde (HCHO) is a common indoor air pollutant.
- Developing effective and sustainable materials for HCHO removal is crucial.
- Chestnut tannin (CT) offers potential as a natural adsorbent.
Purpose of the Study:
- To investigate the HCHO adsorption performance of CT-modified cotton fabrics.
- To analyze the characteristics of CT-modified cotton fabrics for HCHO adsorption.
- To develop cost-effective textiles for HCHO removal.
Main Methods:
- Chemical modification of cotton fabric using CT and 1,4-butanediol diglycidyl ether (BDDE).
- Multilayer assembly of cotton fabric with CT and poly-(diallyl dimethylammonium chloride) (PDMDAAC).
- Characterization of fabric structure and analysis of HCHO adsorption capacity.
Main Results:
- Modified fabric exhibited an increased specific surface area (43.07%) and average pore size (21.3 nm).
- HCHO removal rate exceeded 84% within 2 hours for modified and assembled fabric.
- Maximum HCHO removal rate of 93.22% achieved under specific conditions (pH 12).
Conclusions:
- CT-modified cotton fabrics demonstrate significant potential for efficient HCHO adsorption.
- The developed method offers a cost-effective approach for creating functional textiles.
- These materials show promising applications in air purification and environmental remediation.
