Growth of Nano-ZnO Particles in Cotton Fiber Interiors by in situ Reaction

摘要

ZnO nanoparticles were synthesized directly onto the surfaces, lumina, and cell walls of the cotton fibers at low temperature. Studies showed that the nano-ZnO particles grown in cell walls of cotton fibers were globose particles with diameters around 40 run, but those existing on the surfaces of cotton fibers were hexagonal sheeted crystalline solids and had higher crystallinity. Furthermore, UV-blocking characterization and the fastness to washing of the treated cotton fabrics were estimated. The results showed the treated fabrics provided an excellent UV protection factor rating of 50+, and exhibited a high fastness to washing because Nano-ZnO particles were assembled in fibrous interiors.
