Sigmaplot software 12

The UV/Vis spectrophotometer Lambda 25 (Shelton, CT, USA), which operates in 230–1000 nm wavelength range, was used for the registration of optical absorbance spectra of the formed PANI/GOx, Ppy/GOx, and PTh/GOx composite nanoparticles colloidal solution. The measurements were performed at room temperature in plastic disposable cuvettes of 1 cm optical path length. The optical absorbance of PANI/GOx, Ppy/GOx, and PTh/GOx solutions was registered after the polymerization reaction. UV/Vis measurements were evaluated and presented using SigmaPlot software 12.5 (San Jose, CA, USA).

One-way ANOVA, followed by Tukey’s post-hoc tests were used when comparing multiple means within an experiment. Paired t-tests were used when comparing two means. Significance was defined as p < 0.05. Statistical analyses were performed using SigmaPlot software 12.5 (San-Jose, CA, U.S.A.). Shapiro-Wilk test was used to ascertain normality of the data.
