Reviewer 2 Report
Comments and Suggestions for AuthorsLine 70 – what is it?? Figure 1 is not present here
Line 131 – the word “expect “ is not correct substitute with “except”
Line 147 – the caption is confusing and it is mismacthing what is declared in the text (letters corresponding to films A, A’ etc.)
Lines 162 to 171 – this part is still not clear. Why authors have heated the films and which kind of transformation do they obtain i.e. what does mean transformations like AàB etc.
Comments on the Quality of English Language
I strongly recommend a careful review of English language.

Reviewer 3 Report
Comments and Suggestions for AuthorsThis manuscript has prepared the Rhodamine B reinforced chitosan-based films by the casting method. The mechanical properties, chemical structures, photophysical properties, and antibacterial activities of the film have been characterized. Some major revisions are suggested as below.
(1) It can be seen that films dried at 60℃ and 90 ℃ exhibited different performances, such as mechanical and photophysical properties. Could the author explain why this difference occurs?
(2) Does the content of Rhodamine B have an effect on the properties been studied?
(3) It is recommended to add an error bar to Figure 2 and Figure 3.
(4) The authors mentioned that chitosan in the sample C probably was partially transferred to its base form, please explain why.
(5) Why the maximum emission wavelength of Rhodamine B in solution shorter than the Rhodamine B containing films.
(6) The lifetime of the excited state of Rhodamine B in films is longer than in solution while the fluorescence quantum yields of Rhodamine B loaded films is smaller than free Rhodamine B in solution, why?
Comments on the Quality of English LanguageThe quality of English language is fine.
