“…[10][11][12][13][14] However, there are various important aspects that have to be considered before using these additives in the formulation. Important specifications to consider when using biocides include the compatibility of the compound with the matrix material, the leaching of the biocide agent, its chemical stability at different temperatures, and its performance against different microbes or cells.…”

Polyurethane foams were prepared by using functional quaternary ammonium monomers to endow the porous materials with antimicrobial properties. For this purpose, tri‐ and tetra‐hydroxyl functional quaternary ammonium compounds were synthesized and used as a triol and tetraol monomer in a polyurethane foam formulation. By this method, the cationic ammonium group is chemically incorporated into the polyurethane backbone. Polyurethane foams containing different amounts of the quaternary ammonium functional group were prepared and characterized by means of Fourier transform infrared spectroscopy, carbon solid‐state nuclear magnetic resonance, and scanning electron microscopy. The antimicrobial properties of the cationic polyurethane foams were evaluated toward Escherichia coli and Staphylococcus aureus Gram‐negative and Gram‐positive bacteria, respectively. Polyurethane foams containing more than 20% of quaternary ammonium component display high antimicrobial activity and can be used for several applications requiring antimicrobial properties. © 2017 Wiley Periodicals, Inc.

“…Recent studies have boosted new non-releasing biocide systems, for instance, antimicrobial polymeric materials [7] and coatings with tethered biocides [13,14]. They have provided evidence that the immobilisation of antifouling agents can lead to more controllable and long-term biocidal activity.…”

Water bio-contamination causes serious environmental and economic penalties and health risks in several applications (e.g., freshwater and seawater circuits). In this work, a nontoxic potential strategy able to control this bioburden through new functional bioactive agents, capable of being tethered in polymeric coatings, is presented. Econea biocide was successfully tethered in a silicone-based coating, further used to coat polymeric substrates and monolithic filters. Coated substrates demonstrated promising antifouling effects after being submerged for more than a year in simulated and real conditions. Furthermore, coated monolithic filters showed auspicious growth inhibition and bacteriostatic behaviour for the S. aureus MRSA bacteria.

“…That is, either by introduction of aleaching biocidal agent into the polymer to form a composite or by covalent functionalization of the polymer with the pendent groups that confer antimicrobial activity. Such materials have displayed potent and broad spectrum antimicrobial activity [17]. The polycaprolactone-titania nanocomposites have been shown to decrease surface colonization of Escherichia coli and Staphylococcus aureus [18].…”

Dispersion of functional inorganic nano-fillers like TiO2 within polymer matrix is known to impart excellent photobactericidal activity to the composite. Epoxy resin systems with Ag + ion doped TiO2 can have combination of excellent biocidal characteristics of silver and the photocatalytic properties of TiO2. The inorganic antimicrobial incorporation into an epoxy polymeric matrix was achieved by sonicating laboratory-made nano-scale anatase TiO2 and Ag-TiO2 into the industrial grade epoxy resin. The resulting epoxy composite had ratios of 0.5-2.0 wt% of nano-filler content. The process of dispersion of Ag-TiO2 in the epoxy resin resulted in concomitant in situ synthesis of silver nanoparticles due to photoreduction of Ag + ion. The composite materials were characterized by DSC and SEM. The glass transition temperature (Tg) increased with the incorporation of the nanofillers over the neat polymer. The materials synthesized were coated on glass petri dish. Anti-biofilm property of coated material due to combined release of biocide, and photocatalytic activity under static conditions in petri dish was evaluated against Staphylococcus aureus ATCC6538 and Escherichia coli K-12 under UV irradiation using a crystal violet binding assay. Prepared composite showed significant inhibition of biofilm development in both the organisms. Our studies indicate that the effective dispersion and optimal release of biocidal agents was responsible for anti-biofilm activity of the surface. The reported thermoset coating materials can be used as bactericidal surfaces either in industrial or healthcare settings to reduce the microbial loads. OPEN ACCESSCoatings 2015, 5 96
