Background:

• Graphene oxide (GO) is a precursor for graphene, but its reduction and stabilization can be challenging.
• Developing facile and effective methods for graphene production is crucial for advanced material applications.

Purpose of the Study:

• Characterization of the resulting graphene nanosheets (g-rGO) using FTIR, XRD, Raman spectroscopy, SEM, and TEM.
• Incorporation of g-rGO into a waterborne polyurethane (WPU) matrix.
• Evaluation of the mechanical properties, weatherability, and water resistance of the WPU/g-rGO composites.

Main Results:

• Glucose effectively reduced GO and simultaneously stabilized the resulting graphene nanosheets (g-rGO).
• The g-rGO exhibited good dispersibility and stability in water and the WPU matrix.
• Incorporation of g-rGO significantly improved the mechanical properties, weatherability, and water resistance of WPU.

Conclusions:
