Abstract

In this study, surface modification of silk fabrics was done through adsorbing multi-walled carbon nanotubes (MWCNTs) on the silk fabric surface. For this purpose, a simple method of immersing silk in the solution MWCNTs dispersion was used. In order to increase adsorption of activated MWCNTs on the silk fabric surface, citric acid was used as a crosslinking agent in the presence of sodium Hypophosphite as a catalyst. Results of potentiometric measurements showed that electrical conductivity of CNT modified silk fabric increases with the concentration of CNTs in the solution. Washing fastness of the CNT modified samples were assessed by a spectrophotometer just before and after washing out. Brightness was increased for all samples after washing. Scanning electron microscope (SEM) images was used to investigate morphology of fabric surfaces. SEM images represent that, in the same density, accumulation of single-wall carbon nanotubes was more in samples that obtained in presence of citric acid.
