Abstract: An electroless nickel-plated conductive cotton fabric was prepared by nickel sulfate ultrasonic
activation method. The chemical composition and surface morphology of the coating were characterized by
EDS and SEM. The square resistance, weight gain, abrasion resistance and tensile breaking strength of the
cotton fabric after nickel plating were tested and analyzed. The effects of temperature, pH, mass
concentration of NiSO 4•6H 2O and NaH 2PO 2•H 2O on the weight gain and square resistance of cotton fabric
were discussed. The results showed that the ultrasonic activation conditions were obtained as follows:
m(NiSO 4 •6H 2O)∶m(NaH 2PO 2 •H 2O)∶m(H 2O)=1.5∶2.0∶30.0, 60 ℃, 40 kHz, 320 W and 30 min.
When NiSO 4•6H 2O, NaH 2PO 2•H 2O, C 6H 5Na 3O 7 and CH 3COONa mass concentrations were 25, 25, 5 and
5 g/L, temperature was 90 ℃, pH=5, and reaction time of 1 h，the square resistance of the nickel-plated
conductive cotton fabric was the smallest (71.67 mΩ/□), and the weight loss rate was 3.94% after being
rubbed 18800 times. Palladium-free activated nickel-plated cotton fabric had good electrical conductivity
and abrasion resistance, which can be better applied to smart textiles.
