Cellulose Nitrates-Blended Composites from Bacterial and Plant-Based Celluloses

Round 1

Reviewer 1 Report

The researchers created cellulose nitrate composites by combining celluloses from bacterial and plant sources with different mass ratios. The nitration methods affected the viscosity of the nitrate samples, with the bacterial CN showing a higher nitrogen content. Microscopy techniques revealed a fibrillar nanostructure, while thermal analysis confirmed the high purity and energy density of the composites. These findings indicate the potential of these new materials for advanced energy applications. The study is intriguing, but it is essential to implement major adjustments and address inquiries before considering publication.

Reviewer 2 Report

In this work, the authors synthesized nitrated cellulose (CN) from bacterial cellulose (BC) and oat-hull cellulose (ONC). CN blends of the two resources were characterized, showing a more promising property from CN-BC. The results are sound and comprehensive. I only have the following questions.

1.     In Table 1, the lignin, pentosan, ash contents of BC were labeled as “0.01±0.1(0.05)”. However, this is physically meaningless, because one cannot have negative content percentage. Instead, the authors could have made the label of  <0.01.

2.     Figure 3 needs to be retaken. The quality of the image is very bad. Why use beakers with plastic bag wrappings… Please use standard vials that do not block the visions.
