Reviewer 3 Report
Combining two keywords, the use of eco-friendly materials and 3D image analysis, can be a very good idea. However, there are a few things to consider.
A. It is analyzed without an accurate definition of the material.
A-1. Are the A, B, and C conditions used in the experiment the same sample?
A-2. BS and BL show different tendencies. What is the material difference?
A-3. If you want to explain the characteristics of biopolyols, shouldn't the comparison group be accurately represented?
A-4. In conclusion, we do not know why BS and BL show different trends, and what differences they have from common polyols.
B. Overall, the explanation of the experimental results is insufficient.
B-1. In Figure 6, where specifically does shear break occur?
B-2. Is Figure 10 really necessary?
B-3. It is expected that more diverse data can be obtained if the 3D analysis is performed, but aren't the results showing too definite?
B-4. Is it significant that the average value of the Aspect Ratio is maintained? If it is a mono-cell, there will be a characteristic for deformation, but it is judged that it will not be of great significance in a multi-cell. It seems to be used as a basis for cell collapse.
C. Additional comments
C-1. Wouldn't it be better to convert the Deformation Step to % rather than mm?
C-2. There are no specific material requirements for preparing PU.
