Enhancement of carboxylated single- walled carbon nanotube properties on cotton fabrics using citric acid

Improvement of existing properties and creation of new material properties are the most important reasons for increasing industrial uses of cotton fabrics. In this research work, carboxylated single-walled carbon nanotubes (CSWCNT) were stabilized on a cotton fabric surface, using citric acid (CA) as a cross-linking agent and sodium hypophosphite (SHP) as a catalyst. A scanning electron microscope, electrical contacting equipment, reflective spectrophotometer have been applied to investigate the influence of carboxylated single-walled carbon nano tube on the performance of the cotton fabrics. Also the flammability of cotton fabric modified by CSWCNT, CA and SHP was evaluated using char yield. The test results are compared and discussed and the best sample with optimum properties was selected as CA and SHP pre-CNT treated cotton fabric.
