Fibrous textiles have been increasingly used in a variety of industries.In these applications,the surface properties of textile materials play a very important role.The surface properties of textile materials can be modified by various techniques.Copper(Cu)nanacomposite textiles with diffent thickness of coatings are investigated by atomic force microscope(AFM),energy-dispersive X-ray analysis,and opto-electrical tests.The AFM observations reveal the growth of the Cu nanastructures formed on the fiber surface as the sputtering time increases.The surface conductivity of the textiles coated with Cu nanostructures show a significant increase compared to the nucoated ones.The increased coating thickness leads to better elctrical conductivity.The coated textiles also show considerable improvement in UV and visible light shielding,examined by UV/Vis spectrometer.
