Pulse Reverse Electrodeposition of Spherical Ni-Mwcnt Composite Skein

Watt's bath and pulse reverse (pr) electrodeposition is used to produce spherical nickelmulti wall carbon nanotubes (ni-mwcnt) of 2.00, 0.93, 1.63 and 6.71 urn diameter and a variety of size distributions. for 60 cycles, an absolute electrodeposition current of 18 a/dm^2 is applied atcurrent ratios of ii = i(dissolution)/i(deposition) = 0, 0.077, 0.200 and 0.368. a simple exponential equation is fitted to each pulse response by a resistance-capacitance (rc) simple model giving different timeconstants usable for diagnosing the effect of different parameters. results show that pr electrodeposition is capable of producing microspherical ni-mwcnt composite skeins of differentdiameters and size distributions. this could be identified with the time constant of the process.
