Abstract
Silver nanoparticles were coated on bamboo rayon fabrics (fabrics made from filaments of dissolved and regenerated bamboo pulp fibers) modified with poly(diallyldimethylammonium chloride) (PDDA) under microwave radiation. The silver nanoparticle coated bamboo rayon fabrics modified with PDDA were characterized by fourier transform infrared spectroscopy, X-ray diffraction, energy dispersive X-ray spectroscopy, atomic force microscope and scanning electron microscope. Color properties, ultraviolet (UV) protection, softness and contact angle of the silver nanoparticle coated bamboo rayon fabrics were evaluated. The results show that PDDA is successfully modified on the bamboo rayon fabric. Compared with the bamboo rayon fabrics without PDDA modification, more silver nanoparticles are coated on the bamboo rayon fabrics modified with the PDDA. In addition, the bamboo rayon fabric modified with PDDA is evenly covered with silver nanoparticles. The silver nanoparticle coated bamboo rayon fabric modified with PDDA shows the excellent UV protection with UPF of 223.88 and the hydrophobic property with contact angle of 127°. PDDA modification improves the adhesive strength between silver coating and bamboo rayon fabric.
