Wound healing can be improved through various materials, and nanocomposites are considered promising structures for this purpose. In this study, a PEG hydrogel-cellulose nanocomposite was introduced to enhance wound healing. Molecular dynamics simulations were used to analyze the mechanical stability of the nanocomposite, showing its physical stability at standard conditions. The results demonstrated that the inclusion of cellulose into the PEG hydrogel improved its mechanical performance, making it suitable for clinical applications.
Wound healing can be improved via various materials in clinical cases. Today, nanocomposites are regarded as promising structures for this purpose. In the current computational study, we introduced Polyethylene glycol (PEG) hydrogel-cellulose nanocomposite to improve wound healing. For this purpose, molecular dynamics (MD) simulations were used to analyze hydrogel-cellulose nanocomposite at standard conditions. Therefore, the pre-sent paper investigates the mechanical stability of PEG hydrogel reinforced with cellulose nanofibrils. MD simulations were done in two main phases: equilibrium and deformation process as initial and final phases, respectively. Our simulation results show the defined samples' physical stability at 300 K and 1 bar. This pro-cedure predicted from temperature and total energy convergence after 10 ns. The results of the mechanical test outputs show that inserting cellulose into pure PEG hydrogel leads to improving their mechanical performance. Numerically, the ultimate strength and Young's modulus of the designed nanocomposite increased to 0.26 MPa and 0.39 MPa (respectively) in the presence of 3% cellulose nanofibrils. The increased mechanical strength shows hydrogel-cellulose nanocomposite can be used for wound healing in clinical applications.
