Synthesis and Properties of a Photocurable Coating Based on Waste Cooking Oil

Round 1

Reviewer 1 Report

The authors have made a comprehensive testing on photocurable coating based on 2 waste cooking oil. There are some suggestions to improve the paper:

1. Please explain why A3 has the lowest Tg (Figure S3) while it has the highest crosslinking density?

2. Some readers might want to know the changes in viscosity during photocuring.

3. It might be better if you could provide gloss and yellowing index.

4. Typographical error can be seen such as TG instead of Tg.

Reviewer 2 Report

The study of Synthesis and properties of photocurable coating based on waste cooking oil is indeed very relevant research keeping in mind the demand for sustainable polymer products.

1.     Introduction talks about various research work significance to the waste cooking oil in general but a few sentences about vegetable oil epoxides would be beneficial. It would also be good to add the various recent literature that talks about epoxidized vegetable oil-based coatings All this would let the readers learn about more sources of bio-epoxy and their significances. Most common example of researchers working exclusively into epoxy vegetable oils coatings, tires would be recent papers from notably, Alice Mija, Jomin Thomas, Dean Webster among various others. Review articles are also available by the same authors which is of huge importance to oil  based bio-epoxides applications in the market of coatings. To make authors understand how the current waste oil system compares with bio-based vegetable oil epoxides and the end applications of biobased epoxides expands the scope and opportunity of the discussed research.

2.     A sentence stating why a higher Tg observed in A5 did not translate to a higher cross link density would be good.

3.     A sentence stating the anti-smudge properties of A5 vs A3 would be beneficial.

4.     A picture of the cross cut/adhesion panel after tests in the supporting information if available.

 

5.     The manuscript is well written overall.

Reviewer 3 Report

In this manuscript, the authors reported on the Synthesis and properties of photocurable coating based on waste cooking oil. From this side, this manuscript is interesting to the readers. The topic is important in this field. However, there are several issues needed to be improved and revised before the possible publication in this high-quality journal. A major revision is suggested.

1.    A careful English language revision is strongly recommended through the manuscript.

 

2.    The referee suggests enriching the discussion based on the experimental results, which will be very important for the readers in the relative field. More recent literature is suggested to be included.

 

1.    A careful English language revision is strongly recommended through the manuscript.
