“…PVA and PVA/OA polymer solutions and fabricated polymer films were tested against G + (S. aureus) and G − (E. coli) bacteria using a well diffusion method to determine their potential antibacterial activity (Suganthi et al 2018). Mueller-Hinton agar was prepared and inoculated with the test bacteria.…”

“…Birck et al (2014) proposed the use of a PVA film cross-linked with citric acid and cyclodextrin as a dynamic food packaging material. It is well reported in the literature that PVA or PVA-polymer blends can be cross-linked using multi-carboxylic acids such as oxalic, citric, malic, succinic, and tartaric acid to achieve improved thermomechanical stability for use in packaging applications (Park et al 2001;Gohil et al 2006;Olivato et al 2013;Suganthi et al 2018). While numerous techniques have been proposed for crosslinked PVA networks, few works have undertaken a comparative evaluation of appropriate cross-linkers for PVA films used for food packaging.…”

“…The custom of antibiotics is insecure for the dealing of bacterial illnesses with their infectious (Vignesh et al 2018). Novel strategies are thus critical to perceive and advance the ensuing age of specialists or medications to control bacterial diseases though sanitation preparing, and instance of dousing the microscopic organisms over the genuine antibacterial reagents (Suganthi et al 2018).…”

In this study, organic acids were used as cross-linker with polyvinyl alcohol (PVA) films prepared by a solution-casting method for food packing applications. The effect of incorporating three different organic acids, i.e., malic acid (MA), tartaric acid (TA), and lactic acid (LA), on the physicochemical and biological properties of PVA was explored in detail. The crystalline phase, optical absorption, and functional groups were examined via UV-Vis and Fourier transform infrared spectroscopy. Thermal, microstructural, and surface investigations were conducted by thermogravimetric analysis and scanning electron microscopy, and the antibacterial activity was evaluated. The surface topography and roughness were found to have a strong effect on the bactericidal properties of the films, as confirmed by atomic force microscopy. Among the considered films, PVA/LA exhibited the highest bacterial inhibition, which was largely due to its capacity to modify the local pH and alter the permeability of the microbial layer by disrupting bacteria-substrate interaction. In general, the composite film was found to have attractive properties and can be considered as a food packaging material with low environmental impact based on polyvinyl alcohol.

“…Slight changes are observed in the FE‐SEM images which give detailed observation at different days of culture on the composite coatings . Figure (a‐c) illustrates that round cells are observed on ceramic coating, whereas the cell cultured on TiO 2 ‐SiO 2 bio‐ceramic coating shows poor cell adhesion due to high pH …”

Past few decades witnessed the upcoming of osteomyelitis which is a challenging infectious bone disease. Complications related to this infection is encountered by local drug delivery via orthopedic surgery. In this work, TiO 2 -SiO 2 based bioceramics coatings were fabricated on Ti alloy by anodization method using sulphuric acid and Sodium silicofluoride (SSF) as an electrolyte. Plasma polymerized ethylenediamine (PPEDA) thin film deposited on composites by inductively coupled plasma chemical vapor deposition and followed by ciprofloxacin were used as a model drug by electrodeposition method. The resultant coatings were characterized by FTIR, XRD, FESEM, EDAX and AFM techniques. The mechanical behavior of the composite coatings was evaluated using thickness and hardness tester and electrochemical properties were studied in Ringer's solution. Similarly, CIP@PPEDA/TiO 2 -SiO 2 composite coating on Ti alloy shows good corrosion resistance and better antibacterial efficacy as well as L929 fibroblast cell line, which exhibited a high cell adhesion and high cell viability compared than TiO 2 -SiO 2 and PPEDA/TiO 2 -SiO 2 coatings. All these results suggest that, this newly developed composite coating exhibits superior bioactivity and improved anticorrosion performance on Ti specimen and can be a potential candidate for orthopedic applications.

“…PVA is usually prepared by polymer-analogous saponification of poly(vinyl acetate) which has been polymerised by free radical polymerisation [7]. Nowadays, PVA is employed as an adhesive for packaging applications [8], a sizing agent for paper processing [9,10], a water-soluble glue and modelling material [8], an encapsulation agent, and a dispersing aid [11]. Due to its biocompatibility, this polymer is regarded as safe for coatings in contact with foodstuff and suitable for the preparation of hydrogels for biomedical applications [12,13].…”

Preparation of a Water-Based Photoreactive Azosulphonate-Doped Poly(Vinyl Alcohol) and the Investigation of Its UV Response

2019

Two different azosulphonate dyes were synthesised and purified for the preparation of a water-based photoreactive azosulphonate-doped poly(vinyl alcohol). The aim was the investigation of a novel azosulphonate-poly(vinyl alcohol) photoresist with decreased water solubility after illumination, setting a focus on environmentally benign substances. The electron distribution of the aromatic rings of the two different azosulphonate molecules were changed by the UV-induced cleavage of the –N=N–SO3− groups, which was evidenced by UV spectroscopy. The formation of ester groups was detected by Fourier-transform infrared and 13C nuclear magnetic resonance spectroscopy. UV–Vis spectroscopy was used to investigate the photoreactivity of the prepared films. Photolithographic experiments demonstrated the applicability of these newly produced materials as photoresist materials. In addition, these materials provide high thermal stability.
