Special Issue Information

Dear Colleagues,

the growing interest in a healthy lifestyle in modern society has also caused an increase in the demand for materials showing antibacterial activity. Thanks to such materials, an environment free from pathogenic microorganisms is created in our immediate surroundings. Some polymers have the ability to inhibit microbial growth or even their complete destruction. Due to the type of polymers, as well as the many possibilities of using their antimicrobial properties, the dividing of such macromolecules can be different, and their systematization is not easy. Particular attention should be paid to two parameters: the mechanism of action of polymers, and their chemical structure.

Due to the mechanism of action, polymers are divided into bacteriostatic and bactericidal polymers. The first group consists of polymers which, by acting on the wall and cell membrane of bacteria, inhibit its further development and multiplication. In contrast, biocidal polymers contribute to the complete breakdown of the bacterial cell. Another division, taking into account the combination of the polymer chain with an antibacterial agent, divides polymers into releasing antibacterial agent and the group of contacting, permanent and static antibacterial compounds. Polymers releasing an antibacterial agent unstably bound, most often physical interactions, emit it under appropriate conditions (e.g., temperature or pH change). Such compounds require prior functionalization of the polymer chain with a suitable biocidal compound. The second possibility is polymers whose chains have chemical groups in their structure. The factors permanently associated with the modified surface are more acceptable from this point of view because they do not release into the environment during the using process.

The most popular antibacterial or functionalized polymers with antimicrobial properties include (i) compounds containing quaternary ammonium salts, (ii) halogenated phenols, (iii) nanoparticles of noble metals and metal oxides, or (iv) compounds based on natural biocides. The purpose of this Special Issue is to present the latest solutions in the field of giving polymers antimicrobial properties, the extent of interaction of these compounds and the conditions in which the optimum of these properties is obtained.

Silver nanoparticle (AgNP) and AgNP/reduced graphene oxide (rGO) nanocomposite impregnated medical grade polyviscose textile pads were formed using a facile, surface-mediated wet chemical solution-dipping process, without further annealing. Surfaces were sequentially treated in situ with a sodium borohydride (NaBH4) reducing agent, prior to formation, deposition, and fixation of Ag nanostructures and/or rGO nanosheets throughout porous non-woven (i.e., randomly interwoven) fibrous scaffolds. There was no need for stabilising agent use. The surface morphology of the treated fabrics and the reaction mechanism were characterised by Fourier transform infrared (FTIR) spectra, ultraviolet-visible (UV–Vis) absorption spectra, X-ray diffraction (XRD), Raman spectroscopy, dynamic light scattering (DLS) energy-dispersive X-ray analysis (EDS), and scanning electron microscopic (SEM). XRD and EDS confirmed the presence of pure-phase metallic silver. Variation of reducing agent concentration allowed control over characteristic plasmon absorption of AgNP while SEM imaging, EDS, and DLS confirmed the presence of and dispersion of Ag particles, with smaller agglomerates existing with concurrent rGO use, which also coincided with enhanced AgNP loading. The composites demonstrated potent antimicrobial activity against the clinically relevant gram-negative Escherichia coli (a key causative bacterial agent of healthcare-associated infections; HAIs). The best antibacterial rate achieved for treated substrates was 100% with only a slight decrease (to 90.1%) after 12 equivalent laundering cycles of standard washing. Investigation of silver ion release behaviours through inductively coupled plasmon optical emission spectroscopy (ICP-OES) and laundering durability tests showed that AgNP adhesion was aided by the presence of the rGO host matrix allowing for robust immobilisation of silver nanostructures with relatively high stability, which offered a rapid, convenient, scalable route to conformal NP–decorated and nanocomposite soft matter coatings.
