“…This approach produced exfoliated or mixed intercalated/exfoliated composites. Alver et al [65] prepared polymer/zeolite composite beads by a simple solution blending method using chitosan, polyvinylpyrrolidone and zeolite particles. The synthesized composite beads had relatively large loading capacities for heavy metals, making them a promising material for water treatment applications.…”

Recent advancements in material technologies have promoted the development of various preparation strategies and applications of novel polymer–nanoclay composites. Innovative synthesis pathways have resulted in novel polymer–nanoclay composites with improved properties, which have been successfully incorporated in diverse fields such as aerospace, automobile, construction, petroleum, biomedical and wastewater treatment. These composites are recognized as promising advanced materials due to their superior properties, such as enhanced density, strength, relatively large surface areas, high elastic modulus, flame retardancy, and thermomechanical/optoelectronic/magnetic properties. The primary focus of this review is to deliver an up-to-date overview of polymer–nanoclay composites along with their synthesis routes and applications. The discussion highlights potential future directions for this emerging field of research.

“…The band at 1025 cm −1 also confirmed the presence of siloxane bonds (Si–O–C), which is ascribed to the network structure developed by VTMS . The bands in the region of 550 to 400 cm −1 were attributed to the Si–O–C groups present in VTMS, which developed cross‐linking network between CS and PVP …”

“…The characteristic absorption band at 3500 to 3200 cm −1 was due to the amino group of CS, which was masked by the absorption band of –OH groups also present in CS. The two absorption bands at 2931 and 2873 cm −1 are ascribed to the asymmetric and symmetric vibrations of the aliphatic –CH 2 group, respectively . The sharp absorption band at 1657 cm −1 in HCH‐1 spectrum is due to the –C═O group of PVP.…”

Hydrogel-based drug delivery systems can leverage therapeutically favorable upshots of drug release and found clinical uses. Hydrogels offer temporal and spatial control over the release of different therapeutic agents. Because of their tailor made controllable degradability, physical properties, and ability to prevent the labile drugs from degradation, hydrogels provide platform on which diverse physicochemical interactions with entrapped drugs cause to control drug release. Herein, we report the fabrication of novel vinyltrimethoxy silane (VTMS) cross-linked chitosan/polyvinyl pyrrolidone hydrogels. Swelling in distilled water in conjunction with different buffer and electrolyte solutions was performed to assess the swellability of hydrogels.Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and X-ray diffraction (XRD) analysis were further conducted to investigate the possible interactions between components, thermal stability, and crystallinity of asprepared hybrid hydrogels, respectively. In vitro time-dependent biodegradability, antimicrobial study, and cytotoxicity were also carried out to evaluate their extensive biocompatibility and cytotoxic behavior. More interestingly, in vitro drug release study allowed for the controlled release of cephradine. Therefore, this facile strategy developed the novel biocompatible and biodegradable hybrid hydrogels, which could significantly expand the scope of these hydrogels in other biomedical applications like scaffolds, skin regeneration, tissue engineering, etc.

“…In the first step, all the composite hydrogel films exhibited initial weight loss in the 50–150 °C due to remove of adsorbed water. The second weight loss observed between 200 °C and 270 °C and 300–450 °C corresponded to the decomposition of CH and PVP polymers, respectively . From the TGA results, it was observed that the thermal stability of CH/PVP/MCM‐41 composite hydrogel films was higher than CH/PVP.…”

The aim of this study is to characterize and investigate the effects of the Mobil Composition of Matter No. 41 (MCM-41) concentrations (0.5, 1, 3, 5, and 10 wt%) on structural, thermal, wettability, water content, oxygen (O 2 ) permeability, and swelling properties as well as morphological characteristics of chitosan/polyvinylpyrrolidone/MCM-41 (CH/PVP/MCM-41) composite hydrogel films. In addition, hydrolytic degradability, optic transmittance, and antibacterial properties of composite hydrogels films are determined as in vitro. With increasing of MCM-41 content, the composite hydrogels showed higher thermal stability, as expected. The morphologic properties of the composite hydrogel films are studied using scanning electron microscope (SEM) technique that provide evidence for good miscibility of CH, PVP, and MCM-41. The swelling and water-absorbing properties of the composite hydrogel films are significantly improved because of enhanced hydrophilic profile. Furthermore, the antimicrobial properties of the prepared composite hydrogel films are studied against Bacillus subtilis, Escherichia coli, and Candida albicans yeast. The results showed excellent antibacterial behavior of the composite hydrogel films. The study clearly demonstrates that the prepared CH/PVP/MCM-41 composite hydrogel films may be used as a promising candidate material in various fields such as drug delivery, wound healing material, and adsorbent materials.
