Nanostructured Multilayer Composite Films of Manganese Dioxide/Nickel/Copper Sulfide Deposited on Polyethylene Terephthalate Supporting Substrate

Figure 7

Effect of heat treatment temperatures on the relative surface resistivity of CuS film and Ni/CuS composite film deposited on PET supporting substrate (two coatings of CuS; Ni film deposition conditions: applied potential 2.5 V; duration of 25 minutes; addition of 2.0 g/L SDS).
