Development Of Novel Nanodiamond Composites For Textile Coating

ABSTRACT

This thesis dealt with suitable fabrics to protect human skin from ultraviolet rays (UV) using nanomaterial. Nanomaterials have attracted much of attentions that due to their unique properties demanded in various applications. Their used in textile finishing for imparting advanced functions for textile fabrics attracted many scientists. In this study, novel nanodiamond composites were developed for textile fabrics coating .The nanodiamond were well dispersed in coating by using ultrsonication.

The nanodiamond coating layer effectively absorbed harmful UV rays. The coating layer improved the properties of the untreated textiles. Nine fabrics were used in this project. A coating layer of nanodiamond with binder and acetone were developed and used for coating the fabrics .The fabrics were exposed to ultrasonication then the samples are removed and squeezed out and dried in air which followed by curing in an oven at 120oc for 5 min .

The mass loading of nanodiamonds and ultrasonication time were varied and optimized. Nanodiamonds played a significant role in UV protection and tensile properties .The ultraviolet protection factor of the treated fabrics was significantly enhanced achieving (300%) increase when compared to untreated fabrics .furthermore ,The mechanical and thermal properties of the treated fabrics were improved .The morphology of untreated and treated fabrics was characterized using scanning electron microscope .
