Commenter's Conflict of Interests: I am one of the author

Comment: The article "On the State of Graphene Oxide Nanosheet in a Polyurethane Matrix" provides valuable insights into the characterization of mechanically strong and thermally stable films obtained from a water-based polyurethane dispersion with graphene oxide nanosheet (GO) additives. The use of elemental analysis, X-ray photoelectron spectroscopy, differential thermogravimetry, and Raman spectroscopy offers a comprehensive understanding of the properties of the composite materials.

The identification of the depletion of near-surface layers in nitrogen and the observation of partial reduction of graphene oxide nanosheets, along with an increase in the concentration of defects in its structure, are significant findings that contribute to the understanding of the behavior of GO in a PU matrix.

This research has implications for the development of advanced materials with tailored properties and has the potential to impact various industrial applications. The thorough characterization and analysis presented in this article make a valuable contribution to the field of nanomaterials.

It is a commendable contribution to the field and adds to the growing body of knowledge on graphene oxide nanosheets in polyurethane matrices.
