Functional nano-silver decorated textiles for wearable electronics and electromagnetic interference shielding

The presented research focused on the metallization of polyester, cotton, and polyamide 6.6 fabrics using the silver conductive complex to allow electric conductivity through the fabric's surface and enhance the fabric's mechanical properties. The method used for the metallization of studied fabrics does not require the use of expensive toxic chemicals or electricity, making the process more economically acceptable. The signal attenuation was measured in frequency ranges of 1-4 and 5-12 GHz. After five cycles of metallization, the polyester fabric has higher EMI effectiveness, in a lower range was 45.44 and 57.25 dB. X-ray powder diffractometry (XRD) and infrared spectroscopy with Fourier transform infrared spectrophotometry (FT-IR) characterize the modified tissues. Scanning electron microscopy coupled with energy-dispersion spectroscopy (SEM-EDS) was used to determine layers' morphology and elemental composition. Also, the water and air permeability of modified textiles was determined.
