The synthesis of viscous solution of for preparation of ZnO-NiO NFs was based on our previous papers [29 (link),30 (link)]. Analytical grades of polyvinyl alcohol (PVA, MW = 80,000), zinc chloride dihydrate (ZnCl2·2H2O), and nickel (II) acetate tetrahydrate (Ni(CH3COO)2·4H2O) were provided by Sigma-Aldrich (St. Louis, MO, USA). Deionized (DI) water was utilized as a solvent for the preparation of all solutions. First, PVA was added to DI water and stirred (400 rpm) at 70 °C for 4 h to create a 10 wt% PVA aqueous solution. Subsequently, 1 g of ZnCl2·2H2O and calculated amounts (0.01 wt% to 0.15 wt%) of Ni precursor were added (0.05 mL/h) to the polymer solution and stirred (400 rpm) for 12 h at 70°C. The final viscous solutions (280 mPa·s) for electrospinning were then prepared. The amount of Ni2+ precursor was changed to prepare solutions with different nominal compositions of NiO (0.03, 0.05, 0.07, 0.1, and 0.15 wt%) for the final samples.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
