سلام وقت بخیر  Reviewer 1: Peer-review report to the editor on e-Prime manuscript number PRIME-D-22-00071

Summary

The manuscript (Graphene spin-coated electrode for the copolymer of polyacrylonitrile acoustic nanogenerators) presents experimental results of using a graphene spin-coated electrode for a polyacrylonitrile-based acoustic nanogenerator. The sample characterizing morphology of the fabricated nanofibers were showed in the form of FESEM image and diameter distribution, but without any detailed description and analysis. Meanwhile, the piezoelectric tests in the manuscript were presented in table forms, which is not clear, not informative, and irregular for a scientific research paper. As for the discussion section, I believe quite many previous studies and results were referenced (though the referencing style is not incorrect), which did not reflect and highlight the novelty and amount of work completed by this study.

Under my point of view, the design of electrode for the acoustic nanogenerators and published data need to be improved further. And there are some comments that the author needs to address. Thus, I believe the paper cannot be accepted until great changes and explanations are included in a corrected version of the submitted paper.

Comments to the Authors

1.The expression of the title is not good, I believe the present one cannot reflect the substantive work of this study.

2.The introduction section should be provided with further logical statements, more previous studies and the current conditions need to be included, in addition, the novelty of this study should be highlighted in this part

3.The results were all presented in table form, which is not informative enough and needs to be further analyzed.

4.The result in Table 2 should be showed in Figure form, and detailed analysis should be provided to show the informativeness of this work.

5.The referencing style is non-standard and needs to be correctly renumbered in order.

6.The conclusions section needs to be reorganized and concluded to reflect the importance and significance of this work.

Reviewer 2: The submitted manuscript presents fabrication and investigation of graphene spin-coated ink. It was used in polyacrylonitrile-based nanogenerator for detection of acoustic waves. The manuscript should be improved before it can be considered for publication. The following issues have to be corrected/improved:

1) The important literature on piezoelectric sensors for sonic waves detection is missing. The following papers are recommended: Ultrason. Sonochem. 78 (2021) 105718, ACS Nano 15 (2021) 19783, Sustainable Energy Fuels 5 (2021) 6049, Adv. Mater. 22 (2010) 4726.

2) A novelty of the paper has to be clearly indicated. 

3) FESEM images should be presented as the Figures, not as a Table.

4) Additional characterization of the material is recommended. For example, was the chemical composition of the material investigated?

5) The waveform of piezoelectric output of nanogenerator should be presented.

6) What was the excitation frequency of the used sound?

7) A correlation between sound excitation and piezoelectric output response should be presented.

8) Other piezoelectric properties of the material can be studied. How about the piezoelectric coefficient of PAN, PAN/G, and PAN/Ni ?

9) Future studies and applications of the material should be proposed in the "Conclusion" section.

 هزینه مدت زمان انجام چگونه است؟  از بخش های عملی فقط تست FTIR را میتوانم بگیرم   شما باید متن مقاله و گزارش داده ها را طبق نظر داور اصلاح نمایید  تا ۲۸ اگوست  پروژه هم کار عملیش قبلا انجام شده  Ftir را میگیرم به شما نتایج را جهت گزارش میدهم
