Morphology and properties of nanoscale copper films deposited on polyester substrates

Purpose – Nanoscale copper (Cu) films were deposited onto the surface of polyester fabrics with different structures using radio frequency magnetron sputter coating system at room temperature. The paper aims to discuss these issues. Design/methodology/approach – Scanning electron microscopy (SEM) and field emission scanning electron microscopy (FE-SEM) were used to observe the surface morphology of substrates and the structures of the deposited copper particles, respectively. The capillary flow pore instrument was used to measure pore sizes distribution of polyester substrates. Findings – The experimental results revealed that the fabric structures had a more significant role on the conductivity and electromagnetic shielding effectiveness of samples. The porosity had more apparent effect on ultraviolet transmittance of samples. Originality/value – The results have some theory values on the development of functional textiles.
