“…It was supported by a paper in Hangzhou City, China [21]. Because of its strong nonirritant [22,23], harmlessness, and hydrophilicity [24,25], PVA had been selected for gel preparation among other water-soluble polymers [24,[26][27][28][29]. The PVA gel offers some advantages including easy machinabil-…”

Polyvinyl alcohol/carboxymethyl cellulose (PVA/CMC) composites have attracted considerable attention due to the synergic relation between the two polymers and developing novel blends with improved properties. On one hand, PVA is a versatile polymer with higher mechanical properties compared to CMC. On the other hand, CMC has high biodegradability and biocompatibility, while suffering from poor mechanical properties. Therefore, the blending of the two polymers can help to benefit from the individual component properties. This paper has reviewed the properties and potential applications (e.g. drug delivery, food packaging, and agriculture) of the PVA/ CMC composites.

“…The amount of energy required to break the interactions between the polymer and the cross-linker determines the bond strength of the interaction. If the interaction is stronger, more endothermic energy is required to break the interactions [63]. The cross-linking polymer PVA-E-Pz exhibited multiple endothermic peaks T1 Endo , T2 Endo , T3 Endo , T4 Endo and T5 Endo which were observed at 95.07 °C, 205.60 °C, 304.65 °C, 431.46 °C and 507.11 °C respectively.…”

The spread of microbes which cause infectious diseases are of great concern on human health. Therefore, a water-soluble cross-linked polymer based on polyvinyl alcohol was synthesized via an economical, facile, and aqueous-based approach. The resultant cross-linked polymer was characterized by different techniques such as FTIR, 1H NMR, 13C NMR, TGA, and DSC. The IR spectrum has been recorded in the range 400–4000 cm−1. From thermal studies, i.e. TGA, cross-linking polymer PVA-E-Pz showed two step degradation and from DSC, glass transition temperature (Tg) was exhibited at 86.05 °C. The antimicrobial properties of the cross-linked polymer were studied using the well-diffusion technique and optical density method against gram-negative bacteria, Escherichia coli and gram-positive bacteria, Staphylococcus aureus. Polymer coated fabric was also evaluated for antimicrobial activity against both the bacteria, even after 25 wash cycles the coated fabric showed about 90% antibacterial activity. Samples showed good antimicrobial activity against both the micro-organisms, but more activity was exhibited against gram-negative bacteria. The coating durability and surface morphology of the coated fabric were also analyzed. Cytotoxicity studies revealed that PVA-E-Pz was non-toxic against human dermal fibroblast cell lines. This material might be a good fit for advanced wound dressing and textile applications. The proposed strategy provides a low-cost, environmentally friendly method for creating a new cross-linked polymer with antimicrobial activity. Graphical Abstract

“…The bottle testing method was adopted (Tab. 1) to investigate the gelation time of nanocomposite (PVP-ZnO:RF) and conventional (PVP:RF) hydrogels as this is an inexpensive method (Reena et al, 2020;Sydansk, 1990). The gelant solutions were visually checked after a specific time interval (at 50-90 °C) to find out the gelation time.…”

This work aims at evaluating advancement in water shut-off performance using nanocomposite hydrogel (PVP-ZnO:RF) prepared from PolyVinylPyrrolidone (PVP); used as polymer, Resorcinol-Formaldehyde (RF); used as a crosslinker and nano Zinc Oxide (ZnO); used as strength modifier and it was compared with conventional hydrogel (PVP:RF) i.e., hydrogel without ZnO nanofiller. The ZnO, used as a nanofiller in this work, was successfully bio-synthesized (i.e., green route synthesized) from plant extract (Moringa oleifera leaves) and the average size was found to be 10 nm. In this research work, the effect of ZnO nanofiller on gelation time, gel strength, thermal stability, rheological properties and water shut-off performance was systematically evaluated. On the incorporation of ZnO nanofiller, gelation time decreases but gel strength increases. The thermal stability of hydrogel was studied using a Differential Scanning Calorimeter (DSC) that depicts maximum tolerable temperature increases from 86 °C to 92 °C at 0.5 wt.% of ZnO concentration in nanocomposite hydrogel (PVP). The mechanical stability of the nanocomposite hydrogel (PVP-ZnO:RF) demonstrates that infusion of ZnO nanofiller has significantly enhanced the dynamic moduli (i.e., storage modulus (G′) and loss modulus (G″)). Moreover, the optimum results of storage modulus (G′) and loss modulus (G″) are found at 0.5 wt.% of ZnO nanofiller. The water shut-off performance in the high permeable streak, in terms of percentage reduction in permeability, was 97% and 92% for nanocomposite hydrogel (PVP-ZnO:RF) and conventional hydrogel (PVP:RF), respectively. Also, the residual resistance factor is found to be 31.31 and 12.71 for PVP-ZnO:RF and PVP:RF hydrogels. Thus, the developed nanocomposite hydrogel (PVP-ZnO:RF) may be a promising solution to excessive water production in mature oil fields.
