“…Polyaniline (PANI) belongs to the family of conducting polymers (CPs). Its properties such as controlled electroactivity, facile chemical synthesis, easy doping process, and good environmental stability place it as useful material in a range of applications including microelectronics, battery electrodes, sensors, membranes for the separation of gaseous mixtures, and tissue engineering [ 1 , 2 , 3 , 4 , 5 ]. The usage of CPs in medical areas is constantly growing as the material can be applied for monitoring vital function in living organisms, along with their stimulation [ 6 ].…”

Polyaniline (PANI) was synthesized chemically with the modified rapid mixing protocol in the presence of sulfuric acid of various concentrations. A two-step synthetic procedure was utilized maintaining low-temperature conditions. Application of the modified rapid mixing protocol allowed obtaining a material with local ordering. A higher concentration of acid allowed obtaining a higher yield of the reaction. Structural characterization performed with Fourier-transform infrared (FTIR) analysis showed the vibration bands characteristic of the formation of the emeraldine salt in both products. Ultraviolet–visible light (UV–Vis) spectroscopy was used for the polaronic band and the p–p* band determination. The absorption result served to estimate the average oxidation level of PANI by comparison of the ratio of the absorbance of the polaronic band to that of the π–π* transition. The absorbance ratio index was higher for PANI synthesized in a more acidic solution, which showed a higher doping level for this polymer. For final powder products, particle size distributions were also estimated, proving that PANI (5.0 M) is characterized by a larger number of small particles; however, these particles can more easily agglomerate and form larger structures. The X-ray diffraction (XRD) patterns revealed an equilibrium between the amorphous and semicrystalline phase in the doped PANI. A higher electrical conductivity value was measured for polymer synthesized in a higher acid concentration. The time-of-flight secondary ion mass spectrometry (TOF-SIMS) analysis showed that the molecular composition of the polymers was the same; hence, the difference in properties was a result of local ordering.

“…Accordingly, numerous polymers have been developed as antibacterial Ag NPs supports. In this regard, polymers such as polyaniline and polyacrylonitrile co-maleic anhydride and polymethyl methacrylate have been the focus of some studies [4][5][6][7]. The acrylonitrile butadiene styrene (ABS) is known as a strong and durable production grade thermoplastic employed in many different industries.…”

The present research attempted to characterise the structural and magnetic characteristics of NiFe 2 O 4 @ABS@Ag nanoparticles (NPs) made of nickel ferrite (NiFe 2 O 4), acrylonitrile butadiene styrene (ABS) and silver NPs (Ag NPs), this was done by employing techniques such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy, scanning electron microscopy and transmission electron microscopy, as well as a vibrating sample magnetometer. The XRD patterns obtained indicated that following ABS and Ag NPs coating, the crystallite size (from Scherrer formula) was increased from 32 to 40 nm. It was confirmed by the magnetic measurements that the maximum magnetisation of the NiFe 2 O 4 core was dropped when the surface was coated with ABS and Ag NPs. The antimicrobial activity of this three-component nanocomposite was tested, showing that the nanocomposite NiFe 2 O 4 @ABS@Ag could be isolated from a water solution by using a magnet.

“…For over two decades, developments of organic parts integrated with magnetic nanoparticles have been reported because of their promising properties that are difficult to obtain separately with the individual components [1,2]. Many researchers have been trying to fabricate new composite materials by modifying the magnetic surface with organic molecules or inorganic parts, such as SiO 2 , PANI, APTES, caffeic acid, folic acid, etc., since such new hybrid nanostructures have significant properties due to the their unique multifunctional applications in industrial and biomedical fields [3][4][5][6][7][8][9].…”

In this work, we have described the antibacterial activities of Fe 3 O 4 nanoparticles with different organic parts, including Humic acid (HA), Nicotinic acid (Nico) and Histidine (His), and the antibacterial activity of MnFe 2 O 4 nanoparticles coated with PANI and SiO 2 against different bacteria and some standard antibacterial drugs. The present study revealed that the newly fabricated various Fe 3 O 4 and MnFe 2 O 4 nanocomposites, when combined with some different organic parts, are superiour antibacterial agents. Also, the synthesized nanocomposites can be easily separated from aqueous solution by magnetic filtration without any contamination of the medium.
