Reviewer 2 Report

The aim of the paper is to review the last decades litterature related to the 2D flame readants for PLA; it is notheworty that the topic is interesting and also deeply studied.

Anyway there are many flaws that limit the redibility of the paper; i have listed a few below and authors can find more in the attached file:

1) Acronymus should be explicited the first time the word is used: for example, the first time authors use FR (in the abstract) the acronymus is not explicited;

2) Introduction is too long;

3) the paragraph "PLA feedstock" is too long: because the paper review the FR for PLA, readers don' need a large overview regarding the PLA sources;

4) the PLA synthesis paragraph is too similar to the paper:

DOI: 10.3389/fbioe.2019.00259

Please modify in order to delete the similitudes; moreover the section is too long;

5) I think it is not appropriate to slipt the Processing paragraph in sub-paragraphs: create a single paragraph where authors describe the single techniques;

6) Although the number of references is adequate, it seems that the main section of the paper is simple list of scientific results: the paper quality could be really improved if authors could rearrange that results highlighting different filler aspects, such as effect of fillers dispersion grade on FR, effect of filler functionalities on FR and so on;

The paper could be published but is should be improved considering these aspects together with those reported in the attached file; moreover i suggest to carefully check english style and tipyng errors.

Comments for author File: Comments.pdf

English style should be improved.

Response #4. This section has been revised as per your suggestion/comment.

 

Comment #5. I think it is not appropriate to slipt the Processing paragraph in sub-paragraphs: create a single paragraph where authors describe the single techniques;

Response #5. We have revised the processing portion as a stand-alone section.

 

Comment #6. Although the number of references is adequate, it seems that the main section of the paper is simple list of scientific results: the paper quality could be really improved if authors could rearrange that results highlighting different filler aspects, such as effect of fillers dispersion grade on FR, effect of filler functionalities on FR and so on;

Response #6. As per your valuable comment/suggestion, a column has been added in Table 3 showing the aspect ratio of the utilized 2D NPs used for easy correlation of with the flame retardancy of their host matrix (PLA and/or its blends). Though most of the literatures failed to mention the aspect ratio of the 2D NPs utilized in their studies.

 

Comment #7. The paper could be published but is should be improved considering these aspects together with those reported in the attached file; moreover i suggest to carefully check english style and tipyng errors.

Response #7. The English style has been improved as per your comments.

 

Comment #8. English style should be improved.

Response #8. The English style has been improved as per your comments.

 

 

 

Reviewer 3 Report

It is a very interesting and desirable publication, which will provide authors with many citations. Nevertheless, minor technical corrections are required:
1. In Figure 4 - markings on the x, y, and z axes are hard to read. Please correct it
2. On page 15 we have fonts of different sizes.
3. Improve the quality of Figures 11, 12, 16, 17, 18.

Reviewer 4 Report

The manuscript titled "2D Nanomaterials-based Poly (lactic acid) (PLA) Flame-retardant Materials: Recent Advances and Outlook" presents a promising review of recent advancements in flame-retardants for PLA, with a specific focus on 2D nanosystems and their composites. The abstract effectively sets the stage for the article, conveying the importance of finding ecologically friendly flame-retardant solutions for PLA. The conclusion provides an informative overview of the properties and applications of 2D NMTs, although a stronger connection to PLA flame-retardant materials could be made.

 

The abstract could benefit from including more specific details about the recent advancements and breakthroughs in 2D nanosystems-based flame-retardants for PLA. Mentioning a few key examples or specific findings could help generate more interest from readers.

 

While the abstract provides an overview of the association between flame-retardant loadings and efficiency for different FR-PLA systems, briefly mentioning some key results or trends in this regard might be helpful.

 

The conclusion could be strengthened by directly linking the discussed applications of 2D NMTs, including flame-retardants, with the specific context of PLA nanocomposite systems. This would reinforce the relevance of the discussed 2D NMTs to the main focus of the manuscript.

 

While the conclusion highlights the exceptional properties of 2D NMTs, it might be helpful to briefly mention the challenges or limitations associated with their integration into PLA nanocomposite systems for flame-retardant applications.

 

Overall, the manuscript holds significant potential and relevance for readers interested in the intersection of nanotechnology, flame-retardant materials, and PLA. To enhance the manuscript, the authors may consider expanding on the specific recent advancements and key findings in the abstract and directly linking the properties and applications of 2D NMTs to PLA nanocomposite systems in the conclusion. Additionally, addressing any potential limitations or challenges associated with the integration of 2D NMTs in PLA flame-retardant materials would further strengthen the manuscript.

Based on the provided manuscript, the quality of the English language in the manuscript appears to be moderate. Therefore, moderate editing of the English language is required.
