Reviewer 1 Report
1. The current version of manuscript is like a draft instead of a final version. There are too many typos, the author really needs to improve the writing.
2. The author should improve the logic and writing of introduction, there is no connection between each paragraph, the author just gives a brief introduction of PVA, chitosan and TiO2. More literature for PVA/TiO2 composites or polymer TiO2 nanocomposites should be reviewed.
3. The author should point out why use PVA/chitosan as matrix? What is the role of chitosan in composites? And how does the chitosan influence the properties of PVA/TiO2 composites?
4. There is no mechanical testing, how could the author define the film as flexible in their conclusion?
5. The authors should point out the impact of their studies against other known arts in the literature.

Author's Reply to the Review Report (Reviewer 1)
- The current version of manuscript is like a draft instead of a final version. There are too many typos; the author really needs to improve the writing.
Thank you for your observation, now the current version of manuscript is improved and the language and especially grammar is completely edited by the English language editor to be more clearly (I attached the Certificate of Editing with the revision- and also attached the Track Changes on the supplementary file)
- The author should improve the logic and writing of introduction, there is no connection between each paragraph, the author just gives a brief introduction of PVA, chitosan and TiO2. More literature for PVA/TiO2 composites or polymer TiO2 nanocomposites should be reviewed.
Done, now the introduction is improved and is being more connection between the paragraphs. Beside brief introduction of using PVA, chitosan and TiO2 are inserted in the text. Moreover, more literature for PVA/TiO2 composites is reviewed (Introduction section, Page 2/1st Paragraph/ line 46, Page 2/2nd Paragraph/ line 57, Page 2/3rd Paragraph/ line 73, Page 2/4th Paragraph/ line 97 )
- The author should point out why use PVA/chitosan as matrix? What is the role of chitosan in composites? And how does the chitosan influence the properties of PVA/TiO2 composites?
Done, now the reason for using the PVA/chitosan as matrix, the role of chitosan in composites and how does the chitosan influence the properties of PVA/TiO2 composites are mentioned in the text (Introduction section, Page 2, 2nd Paragraph, line 73)
- There is no mechanical testing, how could the author define the film as flexible in their conclusion?
Thank you for your observation, now removed flexible from the text. Moreover, from several studies highlight to prepare flexible composites by incorporations TiO2 on the PVA/Cs using solution-casting technique. The Incorporating TiO2 nanotubes, during the fabrication may provide a better surface area, total pore volume, and mechanical properties.
- The authors should point out the impact of their studies against other known arts in the literature.
Done, now the impact of their studies against other known is compare with previous studies (Introduction section, Page 2, 1st Paragraph line 46 and cited with Refs No 8.9.10.11)
Comments on the Quality of English Language
The current version of manuscript is like a draft instead of a final version. There are too many typos, the author really needs to improve the writing.

Reviewer 2 Report
The authors prepared PVA/Chitosan films with different amounts of TiO2 additive, and the films were analyzed using XRD, FTIR, EDX, SEM, and AFM. In addition, the electrical characteristics of films were comprehensively investigated. However, there are some additional issues that need to be addressed before publication.1. The full name should provide when it was mentioned at the first time. For example, XRD, FTIR, SEM, AFM, and EDX in the abstract.
2. The authors should carefully check the whole manuscript, there are many mistakes. For example, 0.0.25×10-7 s cm-1 in the abstract.
3. Please elaborate on the statement that "the physical and chemical characteristics of PVA are limited" by providing a detailed explanation of the specific limitations.
4. While the authors have emphasized the advantages of Chitosan in life science, it is crucial to discuss its advantages in the electrochemical field as well.
5. Please focus on highlighting the merits of TiO2 specifically in the electrochemical field, elucidating its beneficial properties and applications.
6. Please provide comprehensive characterization of TiO2, including techniques such as SEM and XRD analysis, to offer a detailed understanding of its structure and morphology.
7. Please rectify the incorrect labels in Fig. 4a and Fig. 5d to accurately represent the experimental results.
8. Please discuss the advantages resulting from increased roughness and hydrophilicity in the PVA/Chitosan blend covered by TiO2, addressing their significance in the context of the study's objectives.
9. What’s the reason for the smoother surface of PVA/Cs/0.05TiO2 as compared to PVA/Cs/0.01TiO2 ?
10. Please determine the optimal sample based on the defined criteria and evaluation parameters, considering the desired properties and performance requirements.
11. What’s the impact of different ratios of PVA and Chitosan on the electrical characteristics of the sample?
The format problems and English Language in this paper need to pay more attention. The font size of in Figure 1, for instance, is inconsistent.

5. Improve the FT-IR results and discussion.
6. Typological errors –rectify.
7. Revise the keywords.
8. There are two 4 b pics. Provide 4a pic.
