FT-Raman Spectroscopy and Electrical Conductivity on Cotton Fabrics via Single-Walled and Carboxylated Single-Walled Carbon Nanotube Treatment

Cotton fabrics were treated with single-walled and carboxylated single-walled carbon nanotubes by sonicator exhaustion method for three different times (15, 30 and 45 minutes). FT-Raman spectroscopy has been used for characterization of different carbon based materials. By increasing the time of carbon nanotube (CNT) treatment, the band assignment has been changed to other wave numbers related to each band. The morphology of the modified surfaces has been investigated using scanning electron microscopy
(SEM). The surface morphology of treated samples was confirming the carbon nanotubes on the surface of cotton samples. Electrical resistance of treated samples was also assessed. According to the results, the electrical resistance of treated cotton with carbon nanotubes reduced significantly. However, more amounts of CNT observed on the surface of cotton fabric in the case of using carboxylated single-walled carbon nanotubes and is more useful to increase the conductivity.
