Enriched adhesion of talc/ZnO nanocomposites on cotton fabric assisted by aloe-vera for bio-medical application.

Synthesis and characterization of talc/ZnO nanocomposites with the assistance of aloe-vera are investigated by structural and morphological studies. The crystal structure and the phase analysis of ZnO and talc are characterized and confirmed by X-ray diffraction (XRD) analysis. The average crystallite size estimation from the Scherrer formula and the particle size analysis clearly predicts that the size of the ZnO declines when aloe-vera is used as a capping molecule in comparison to the commercially available ZnO. The reduced crystallite size of ZnO renders a stable cohesion with the talc composition and the presence of distinct functional group pyridines/ammonia in the synthesized nanocomposites enriches the good adhesion between the as-synthesized material and cotton fabric. The adhesion and homogeneous distribution of talc/ZnO nanocomposites on the cotton fabric are inferred from the scanning electron microscopy (SEM) results. The basic studies and characterizations would pave way for futuristic bio-medical application. [ABSTRACT FROM AUTHOR]
