Round 1

Reviewer 1 Report

Liang and his co-workers have fabricated flexible electric-heating composites from graphene oxide (GO) and cationic cellulose nanofiber (CCNF) using vacuum filtration, and investigated the structural morphology, tensile strength, electrical conductivity, electric-heating performance, and cycle stability of synthesized composites. Films were characterized using SEM, TG, and DTG techniques. The manuscript, in general, is well-written, well-organized, and figures are well-designed and illustrative. The topic of the manuscript fits the scope of the journal. I suggest acceptance of this manuscript in its present form.   

Reviewer 2 Report

The manuscript titled 'Conductive biomass films containing graphene oxide...' by S. Liang et al. describes a composite made from graphene oxide and cellulose. The most important characteristic was the electrical conductivity, that was increasing with the content of graphene oxide; besides, the film demonstrated a very stable electric-heating cycle, that can find attractive applications in research or industry. 

The composite film was characterized by mechanical testing, SEM, Raman, TGA and DTG. As a suggestion, maybe it was interesting to add also the IR spectrum. The discussion and the experimental data supports the conclusions of the work. The manuscript has 34 references in the correct format.

The possibility to make the composite as film greatly support possible important applications. In conclusion, the manuscript can be accepted for publication as it is.
