Preparation and Characterization of ChitosanZinc Oxide Nanoparticles for Imparting Antimicrobial and UV Protection to Cotton Fabric

Abstract EN

Synthesis of chitosan/ZnO nanoparticles was performed using different concentrations of ZnO at different temperatures.

Nanoparticles of ZnO/chitosan were prepared in rod form with average length 60 nm and average width 5–15 nm.

Thus, obtained nanoparticles of ZnO/chitosan were characterized using UV spectrophotometer, FTIR, TEM, X-ray, and SEM.

Size and shape of chitosan/ZnO nanoparticles relied on conditions of their synthesis.

Notably, chitosan/ZnO in rod form with average length of 60 nm and average width 5–15 nm could be achieved.

Application of chitosan/ZnO nanoparticles to cotton fabric conferred on the latter antibacterial and UV protection properties.

Cotton fabric was characterized using SEM, ultraviolet protection factor (UPF) rating, and antibacterial (gram-positive and gram-negative) characteristics.

Finished cotton fabric exhibited good antibacterial properties against gram-positive and gram-negative bacteria.

The UV testes indicated a significant improvement in UV protection of finished cotton fabric which is increasing by increasing the concentration of nanoparticles of ZnO/chitosan.
