Scanning electron microscopy (SEM) showed that the diameters of the obtained composite fibers were about 30–200 nm at different Fc concentrations. Thermogravimetric analysis (TGA) results confirmed the presence of ferrocene within the

• Fc in the PVP polymer is in the amorphous form with a poor degree of crystallization. The degradation process of products was investigated using thermogravimetric analysis (TGA) from 20 to 600 °C in nitrogen gas. Figure 3a represents the TG curve of the pure Fc. It was found that the TGA data of Fc

• thermogravimetric analysis (TGA) [40]. The subsequent ARGET ATRP was carried out by using ascorbic acid (AA) as the reducing agent and anisole as the solvent. Ascorbic acid is insoluble in anisole, hence, the reduction of the Cu(II) complex takes place at the surface of solid ascorbic acid. The slow reaction rate
