“…Similar results were found for polyethylene surface-modified by plasma immersion ion implantation. 11 Recent work by Asadinezhad et al 12 developed a novel surface active antibacterial medical-grade PVC by coating Irgasan as antibacterial agent onto the PVC, which was surface-modified by a multistep physicochemical approach, to impart antimicrobial properties, that was assessed through the agar diffusion test method. They found an improved hydro-philicity on the sample surface and bacteriostatic characteristics of the Irgasan coated samples.…”

Triclosan was used as antibacterial agent in various vinyl thermoplastics and calcium carbonate (CaCO 3 )/thermoplastic composites and the antibacterial performances were studied through Halo and Plate-CountAgar (PCA) test methods. The thermoplastics used were polyethylene (LDPE, MDPE, HDPE), polypropylene (PP), polystyrene (PS) and poly(vinyl chloride) (PVC). Escherichia coli (E.coli, ATCC 25922) and Stapphylococcus aureus (S.aureus, ATCC 25923) were used as the testing bacteria. The color index results suggested that introducing triclosan did not change the color of all thermoplastics used. The antibacterial results showed that the inhibition zone increased with increasing triclosan for nonpolar thermoplastics like LDPE, MDPE, HDPE, PP, and PS films whereas the opposite effect was observed for polar PVC film. The antibacterial efficacies of the triclosan decreased in the order of LDPE > MDPE > HDPE > PP > PS > PVC and this was confirmed by the triclosan releasing and FT-IR results. The differences in the antibacterial performances of the studied thermoplastics with triclosan were associated with their rigidities, abilities to crystallize, and free volume or molecular density. The sensitivities of E.coli and S.aureus bacteria to the triclosan were found to be dependent on the testing methods used for the antibacterial performance evaluations. The addition of CaCO 3 worsened the antibacterial performances in the triclosan filled HDPE and PS blends, but had a benefit for improved bacterial reduction in the triclosan-filled PVC blend.

“…The function is similar to the previous case -the antimicrobial agent is released from the surface and deactivates any potentially present bacteria. The advantage of this technique lies in its activity over a long period of time [39,42,43]. Nevertheless, the complexity of the modification process can prove limiting for this method.…”

In this work, novel amphiphilic pyrazole-g-polyglycidyl methacrylate-based polymers have been prepared, characterized, and evaluated for antimicrobial activity. The pyrazole derivative (4-(4-chlorophenyl) azo-1H-pyrazole-3, 5-diamine) is grafted to the epoxy rings of polyglycidyl methacrylate and poly (glycidyl methacrylate-co-methyl methacrylate) copolymers. The structure verification was performed using FT-IR and TGA analyses. Finally, the novel pyrazole-g-polyacrylates copolymers were tested against different gram-positive and gram-negative bacteria strains. All the derivatives show antimicrobial activity against both gram-positive and gram-negative bacteria strains with varying degrees. Pyrazole-g-PolyGlycidyl methacrylate shows the most potential antibacterial activities followed by pyrazole-g-poly (glycidyl methacrylates-co-methyl methacrylate) copolymers where the polymethyl methacrylate content show a determining effect. Minimum inhibition and biocide concentrations were determined and compared with gentamicin and ketoconazole antibiotics.
