Nanowire fabrication on cotton surfaces: effect of the pretreatment

Abstract

Anisotropic nanostructures such as nano-wires, nano-tubes, nano-rods, nanoribbons, nano-layers, etc. are extremely attracted due to their larger surface area as compared to nano-particles. This research has targeted at fabrication of the metallic nano-wires through a simple one-step pad-dry method. The effects of mercerizing as one of the most common and important finishing treatments on cotton fabrics have been investigated. Mercerized and un-mercerized fabrics with the same structures have been treated and compared. SEM micrographs confirmed fabrication of the nano-wires with a high aspect ratio on the fiber surfaces oriented parallel with fiber axes. An enhanced potentiality for growing nano-wires with higher level of orientation has been observed for mercerized fabrics compared to un-mercerized ones. As it is well known, mercerizing can cause some structural changes in cotton fibers. Reduction of crystallinity as a result of this process (mercerizing) leads to increasing the amorphous regions which have a good potentiality for growing nano-structured materials. The higher moisture regains, absorbency, smoother morphology, etc. caused by mercerizing can direct the better growth of nano-structures on mercerized fabrics.
