Synergistic effect of graphene oxide and sodium carboxymethylcellulose on the properties of poly(vinyl alcohol) hydrogels

Abstract

Hydrogels are a promising candidate for applications in biomedicine and bioengineering, but their mechanical properties often restrict their applications. To improve the mechanical performance of poly(vinyl alcohol) (PVA) hydrogels, we introduced sodium carboxymethylcellulose (CMC), and graphene oxide (GO) into them. We prepared a series of composite hydrogels composed of PVA, CMC, and GO with epichlorohydrin as a chemical crosslinker. We used Fourier transform infrared spectroscopy and X-ray diffraction to characterize the chemical structures of GO and the hydrogel. The dynamic mechanical analysis results show the synergistic enhancement effects of CMC and GO on the PVA hydrogel. The swelling process of the hydrogels also fit well with the second-order kinetic equation. Scanning electron microscopy results suggest that the neat mesh structure facilitated superior mechanical properties in the hydrogels.

Physicochemical modification of hydroxylated polymers to develop thermosensitive double network hydrogels

“…In recent years, biomaterials such as macromolecules, graphene oxide, molybdenum sulfide, and CNT are considered key components in medical and health care material research 1–3 due to their unique properties, including high mechanical strength, stability, and excellent electrical behavior 4 . For example, the fracture stress of the nanometer lamella of graphene oxide has been reported to be ∼ 63 GPa 3 . Many different class of biomaterials, such as, carbon‐based materials, 5 polymers, and hydrogels, 6 have been widely investigated for biomedical and bioanalytical applications 3,7,8 .…”

Adsorptive Removal of Drimarene Brilliant Blue by Thermo Stable, Eco-friendly Graphene Oxide Reinforced Polyvinyl Alcohols Hydrogels With High Reusability Potential

“…Carbon-based materials like GONPs are the most promising adsorbents due to their high chemical stability, high surface area, and excellent aqueous amphilicity [4]. These fascinating properties of graphene oxide are mainly derived from its unique chemical structure composed of small sp 2 carbon domains, surrounded by sp 3 carbon domains and oxygen-containing hydrophilic fundamental groups such as hydroxyl and carboxyl [8]. GO is extensively used as nano-filler in the polymeric materials, dispersed readily in the matrix of hydrogel and can efficiently develop strong interactions.…”
