Fabrication of Graphene Oxide Reinforced Bio‐Nanocomposite Films with Antibacterial Potential

Abstract

The antimicrobial properties of graphene oxide (GO) have triggered a strong interest in the development of GO-based antimicrobial polymer nanocomposites. GO incorporated polyvinylpyrrolidone (PVP) and carboxymethyl cellulose (CMC) blend-based polymer nanocomposites are developed for antibacterial applications. The successful synthesis of GO is confirmed by transmission electron microscopy while the fabrication of CMC/PVP blend and CMC/PVP/GO is confirmed through FT-IR spectroscopy and X-ray diffraction (XRD) analysis. The morphological characteristics of polymer nanocomposites are studied using scanning electron microscopy. The films are also characterized using energy dispersive spectroscopy (EDX) which reveals the successful inclusion of the GO sheets in the polymeric matrix. The antibacterial efficacy of polymeric nanocomposite is tested against Gram -ve bacterial strain (Escherichia coli The CMC/PVP/GO nanocomposites exhibited inhibition of bacterial cell growth. IntroductionMany research reports have been dedicated recently toward the development of nanomaterials with antimicrobial properties. The need for antimicrobial materials is ever-present with the increasing demand in the food packaging and health care sector. In this regard, nanomaterials with antimicrobial properties hold a great promise in developing antimicrobial technologies. These antimicrobial nanomaterials find applications in fields such as food, synthetic textiles, environmental, medical, and packaging. [1] Among the various nanomaterials, the carbon-based nanomaterials have drawn a particular interest of researchers as promising antimicrobial agents. However, the exploitation of carbon-based nanomaterials is often challenging due to their low

Fabrication of pH-stimuli hydrogel as bioactive materials for wound healing applications

“…2 . The broadband 3600-3200 cm − 1 was due to – OH functional groups available in GO, TEOS, PVA, gelatin, and CMC, confirming the intra/inter hydrogen bonding [ 30 , 31 ]. The peak positions at 1157 and 1064 cm −1 are because of stretching vibration C–O and O–H and attributed to the pyranose and confirm the effective crosslinking of gelatin, PVA, and CMC throughout the spectral profile via TEOS as crosslinker.…”

“…[23][24][25][26] Meanwhile, SA and CMC can produce strong intermolecular interactions between the polymers through hydrogen bonding, which improves the mechanical properties of the lm, resulting in a lm with better performance and lower cost. 27 Nonetheless, there has been no detailed research on the combination of SA, CMC, and other materials into new active packaging, and the effect of adding different materials on the packaging is unknown.…”
