“…6. After 1 h contact at room temperature in PBS, PC1 showed a significant log reduction of E. coli, and S. aureus but the control samples (PANI-PEO) resulted an only slight reduction, as expected since PANI has known antimicrobial properties [34,35], When the amount of PC1 was increased the PC1 fibers were able to completely kill E. coli and S. aureus at 1.0 mg and 0.5 mg/mL, respectively (Fig. 6a,b).…”

“…Conducting polymers such as polyaniline and polypyrrole have already proven their microbial resistance properties in many fields such as antifouling or antimicrobial coatings, − biomedical, ,− and food packaging. − Due to their superior properties against controlling the microbial colonization of various surfaces and the development of resistant microbe strains, they have been recently explored for disinfectant applications as well . These polymers possess unique properties such as ease of synthesis on a large scale, excellent environmental stability, a tunable backbone (−NH 2 ) for tailoring as antibacterial materials, flexibility for functionalization, and doping …”

The ongoing worldwide pandemic due to COVID-19 has created awareness toward ensuring best practices to avoid the spread of microorganisms. In this regard, the research on creating a surface which destroys or inhibits the adherence of microbial/viral entities has gained renewed interest. Although many research reports are available on the antibacterial materials or coatings, there is a relatively small amount of data available on the use of antiviral materials. However, with more research geared toward this area, new information is being added to the literature every day. The combination of antibacterial and antiviral chemical entities represents a potentially path-breaking intervention to mitigate the spread of disease-causing agents. In this review, we have surveyed antibacterial and antiviral materials of various classes such as small-molecule organics, synthetic and biodegradable polymers, silver, TiO2, and copper-derived chemicals. The surface protection mechanisms of the materials against the pathogen colonies are discussed in detail, which highlights the key differences that could determine the parameters that would govern the future development of advanced antibacterial and antiviral materials and surfaces.

“…Figure 2 shows the FTIR spectra of pPD and Fe-pPD composite with their respective peaks. The pPD spectrum shows a typical broad band between 3200 and 3400 cm −1 attributed to the presence of stretching vibration of N-H group and hydroxyl group (-OH) stretching from physically adsorbed H-O-H bonded to the surface [ 26 , 39 ]. The appearances of strong peaks at 1677 and 1504 cm −1 relate to the C=C and C=N stretching vibrations of the phenazine ring [ 40 ].…”

Water is regarded as an important natural resource to sustain life, and its purification is an important criterion that determines its quality and usefulness. In this study, the incorporation of Fe3+ oxide onto a phenylenediamine (pPD) polymer matrix through chemical co-polymerization was prepared, and its arsenite and fluoride removal potentials at optimal conditions from aqueous solution were evaluated. The morphology and structural analysis of the synthesized Fe-doped pPD (Fe-pPD) were comparatively evaluated using the FT-IR, SEM, EDS, and XRD techniques. Fe was successfully incorporated onto pPD matrix as confirmed by different morphological characterizations. The rate of adsorption of F− and As3+ onto the Fe-pPD composite best followed the pseudo-second-order kinetic model. The experimental data for both As3+ and F− onto the Fe-pPD composite better fit the Freundlich isotherm model at different operating temperatures. Overall, the synthesized composite exhibited a strong affinity towards fluoride uptake (96.6%) than arsenite uptake (71.14%) with a maximum capacity of 6.79 (F−) and 1.86 (As3+) mg/g. Additionally, the synthesized adsorbent showed some level of antimicrobial activity against common water-borne bacterial. Therefore, the Fe-doped pPD composite has the potential ability for inorganic metal species pollutants remediation and bacterial disinfection in community-level water purification processes.
