This study presents an innovative approach to creating environmentally friendly nanosheets with notable stability and biodegradability. One aspect that caught my attention is the oil-repellent properties tested using chili oil. Could the authors comment on whether these nanosheets exhibit similar performance with industrial oils or mixtures, which often have different viscosities and compositions?
Additionally, the capped nanosheets demonstrated 58% biodegradation after 120 days. Were any degradation by-products analyzed to assess their environmental safety or potential toxicity? This data would strengthen the argument for these materials’ broader ecological benefits.
While the spray-coating method simplifies application, could the authors discuss how scalable this approach is for large-scale industrial use, particularly in terms of maintaining uniform nanosheet distribution on diverse substrates?
