摘要

In this study, we present a cellulose-based nanocomposite enhanced with MoS2 nanoparticles to improve their hydrophobic and antimicrobial characteristics. The MoS2 synthesized via a hydrothermal method was incorporated into cellulose acetate (CAc) using a simple phase inversion method. X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) verified the effective formation of CAc-MoS2 nanocomposite. The scanning electron microscopy (SEM) images revealed that the pure CAc sample had a porous surface, whereas the incorporation of MoS₂ nanoparticles resulted in surface roughening and reduced porosity. Antimicrobial tests with Escherichia coli and Staphylococcus aureus demonstrated that CAc-MoS2 nanocomposite possess superior resistance compared to pure CAc. The water absorption capacity of pure CAc and CAc-MoS2 nanocomposite was 96.5% and 67%, respectively, confirming the enhanced hydrophobic properties of the nanocomposite, which makes it ideal as wound dressing material. Alongside the experimental studies, a neural network model was developed to forecast the antibacterial properties of the CAc-MoS2 nanocomposite. The model demonstrated a strong correlation with the experimental data, achieving an R2 value close to 1. In short, the current method can illuminate the design of antibacterial materials with promising applications in wound dressings to satisfy the requirements of an increasing antimicrobial resistance bacterial issue.
