“…The anodic and cathodic peak currents were linearly proportional to the square root of the potential sweeping speed highlighting a process controlled by diffusion of the [Fe(CN) 6 ] 3-/4-ions to the electrode/solution interface. 28 Moreover, increasing the potential sweeping speed causes a growing separation between the anodic and cathodic peaks for all electrodes.…”

“…The charged functional group should arrange the charges at the surface, since there are a minor amount of amino in the region of the double layer, this generates a more efficient arrangement of electrical charges, therefore reducing the size of the electric double layer. 26 Studying the redox process of an electroactive species, such as the [Fe(CN) 6 ] 3-/4-redox couple, is a convenient tool to monitor the kinetic barrier to electron transfer at the electrode/solution interface. 27 Figure S3 (SI section) shows cyclic voltammograms for the five compositions in presence of the [Fe(CN) 6 ] 3-/4-redox couple at different sweeping speeds.…”

“…The polymer displays properties that are different from organic polymers. [6][7][8] Most polyorganosiloxanes are of variable-viscosity fluids due to their relatively small intermolecular interactions caused by the methyl groups in the main chain of these polymers. Chain reticulation is necessary to obtain a polymeric network from polyorganosiloxanes.…”

“…Materials with different amounts of PDMS were prepared and characterized by thermogravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FTIR). The conductive properties of the electrodes were assessed by cyclic voltammetry (CV) using [Fe(CN) 6 ] 3-/4-as a probe molecule, electrochemical stability studies were also performed and the effect of two different supporting electrolytes on the electrochemical response was investigated. In addition, electrochemical impedance measurements were performed, the electrodes were used to detect copper(II) cations in aqueous solution with square wave voltammetry measurements and in an analytical determination of real sample, an artisanal sugarcane spirit.…”

Graphite was incorporated to a polydimethylsiloxane (PDMS) polymer network functionalized with amino groups to obtain an electrode material and used to detect copper ions in aqueous solutions and sugarcane spirit. The polymer network was prepared with PDMS, 3-aminopropyltrimethoxysilane (APTMS), tetraethyl orthosilicate (TEOS) with addition of graphite to obtain the electrode material. The materials were prepared with different mass concentrations of PDMS: 0, 3, 6, 12 and 18%; and characterized by thermogravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FTIR). Quasi-reversible behavior was found when studying the [Fe(CN) 6 ] 3-/4-redox probe and were electrochemically stable up to 100 consecutive cycles. Electrochemical impedance measurements showed a second time constant at high frequencies for the PDMS electrodes, indicating a second phase in the polymer network with resistive properties, probably due to an increase in the material polymerization resistance. Square wave voltammetry studies were conducted with these electrodes to detect copper(II) ions in aqueous solution. The electrode proposed was applied to determine Cu 2+ in a real sample, sugarcane spirit. The PDMS electrodes prepared here presented a potential to be applied as electrochemical sensors for detecting copper ions.

This Focus Review describes state-of-the-art methods for the preparation of antimicrobials ilicones. Given the diversity of antimicrobiala ctivity and their mechanisms, the performance of these materials is highly dependento nt he characteristics of the polymeric matrix. Therefore, different synthetic routes have been developed, such as 1) physical treatments,2 )chemical transformations, and 3) copolymerization. This classification is not exclusive,s os ome products belong to more than one class. Herein, we attemptt op resent ah andy overview of the development of antimicrobial silicones, their most important application fields, the most relevant antimicrobiala ssays,a nd, as the title suggests, an overview of the most relevant preparation methods.

In the present study, cellulose acetate (CA) nanofibers were prepared by electrospinning technique. Alkaline hydrolysis was introduced for conversion of CA nanofibers to cellulose nanofibers.Nanofibers were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FTIR). Furthermore, silver nanoparticles (AgNPs) were incorporated on regenerated cellulose nanofibers with different concentrations and used as an antimicrobial agent against Gram negative Escherichia coli BH5 α, Gram positive Spectromyces arenus, and Aspergillus flavus. Strong inhibition activities were determined.
