“…As Table shows, elongation at break diminishes alongside rise in the amount of GA in the cross‐linked film. The similar results have also been reported for PVA‐glutaraldehyde blend films by other researchers . The increasing elongation at break could be due to formation of a more rigid and compact network with an increasing content of crosslinking agent, consequently reducing the number of hydrophilic hydroxyl groups in the polymer chains.…”

This work is focused on novel methodology of poly(vinyl alcohol) crosslinking by non-toxic dicarboxylic acid, glutaric acid. The cross-linked system was used as a matrix for immobilization of bacteriocin nisin. Effect of the crosslinking degree on physico-chemical, morphology, mechanical, and thermal properties of poly(vinyl alcohol) films were investigated by using swelling test, Fourier transform infrared spectroscopy, scanning electron microscopy, stress-strain analysis, differential scanning calorimetry, and thermogravimetry. Release profile of the nisin from the cross-linked poly(vinyl alcohol) was studied by high performance liquid chromatography. Antibacterial activity of the prepared systems was tested by agar diffusion test and dilution and spread plate technique. Results showed suitability of glutaric acid as effective crosslinking agent of poly(vinyl alcohol) that acts synergistically with bacteriocin nisin against the tested Gram-positive and Gram-negative bacterial strains.

“…However, the processing complexity and residual monomer are main concerns. Chemical crosslinking modification is a facile method to immobilize UV absorbers in PVA matrix through introducing some chemicals (such as dicarboxylic acids, dianhydrides, diisocyanates, and dialdehydes) and thus enhance the UV‐protection property of PVA materials . For instance, Zahra et al .…”

[42][43][44] For instance, Zahra et al 44 fabricated the crosslinked PVA films via mixing PVA and quaternary ammonium modified starch utilizing glutaraldehyde as crosslinker, which exhibited favorable mechanical, antibacterial, and UV-shielding properties. However, the generation of byproducts, un-green procedure, and harmful chemical residue is major problems.…”

Although many preparation approaches have been developed, it remains a huge challenge to achieve ultraviolet (UV)‐protection films that combine high transparency, excellent UV‐shielding, and mechanical properties. Herein, we demonstrate a facile and eco‐friendly process for fabricating strong, flexible, and transparent UV‐protective poly(vinyl alcohol) (PVA) films by exploiting silicomolybdic acid (SiMoA) as UV absorber and reinforcing phase. Fourier‐transform infrared analysis confirms the formation of strong hydrogen‐bonding interactions between PVA and SiMoA. The glass‐transition temperature, mechanical properties, and UV‐shielding stability of the UV‐protective PVA composite films obviously increase with increasing the content of SiMoA. By incorporation of only 2 wt % SiMoA, the UV‐protective PVA composite film can block more than 90% of UV light in the entire UV regions and retain high visible light transparency (up to 95%). Simultaneously, the UV‐protective PVA composite film presents excellent mechanical properties with a tensile strength of 65.2 MPa and an elongation at break of 172.6%, which are 72.0 and 69.5% higher than that of pristine PVA films. This work provides a simple but effective approach for creating strong, flexible, and transparent UV‐blocking polymeric materials via hydrogen‐bonding assembly, which are expected to have wide application prospects in UV‐protection field. © 2019 Wiley Periodicals, Inc.

“…Non-released antibacterial materials have been synthesized in many dental materials [21,22,23,24,25] and demonstrated good antibacterial effect. Quaternary ammonium methacrylates (QAMs), such as 12-Methacryloyloxydodecyl-pyridinium bromide (MDPB), can be copolymerized and covalently bonded in resins, immobilizing and exerting a contact-killing capability against oral bacteria and biofilms.…”

Heat-Polymerized Resin Containing Dimethylaminododecyl Methacrylate Inhibits Candida albicans Biofilm

et al. 2017

The prevalence of stomatitis, especially caused by Candida albicans, has highlighted the need of new antifungal denture materials. This study aimed to develop an antifungal heat-curing resin containing quaternary ammonium monomer (dimethylaminododecyl methacrylate, DMADDM), and evaluate its physical performance and antifungal properties. The discs were prepared by incorporating DMADDM into the polymer liquid of a methyl methacrylate-based, heat-polymerizing resin at 0% (control), 5%, 10%, and 20% (w/w). Flexure strength, bond quality, surface charge density, and surface roughness were measured to evaluate the physical properties of resin. The specimens were incubated with C. albicans solution in medium to form biofilms. Then Colony-Forming Units, XTT assay, and scanning electron microscope were used to evaluate antifungal effect of DMADDM-modified resin. DMADDM modified acrylic resin had no effect on the flexural strength, bond quality, and surface roughness, but it increased the surface charge density significantly. Meanwhile, this new resin inhibited the C. albicans biofilm significantly according to the XTT assay and CFU counting. The hyphae in C. albicans biofilm also reduced in DMADDM-containing groups observed by SEM. DMADDM modified acrylic resin was effective in the inhibition of C. albicans biofilm with good physical properties.
