## 5 Conclusions  
The method of coating AN with NC or MNC is a highly interesting advancement; however, due to its very early technological state, it is not without issues. The most relevant limitation of the process is the control over the microstructure of the final product (i.e., unreliability of producing the desired core-shell structures), while the issues of resource consumption (use of large solvent volumes per unit mass of the product) also need to be addressed prior to scaling up the process and implementing it as a technology. An important aspect of the process is the choice of mixture used to conduct the esterification of cellulose, with the KNO\({}_{3}\)/H\({}_{2}\)SO\({}_{4}\) mixture affording better process control, but requiring adjustments of the process due to the incomplete removal of cellulose sulphate from NC-KNO\({}_{3}\) and MNC-KNO\({}_{3}\) samples. In terms of EM formulation design, the use of AN and diesel oil appears to be a favourable choice, as it translates into reduced mechanical sensitivity of the cellulose nitrate, while being expected to provide a significant increase in energetic performance, when compared to traditional ANFO-type EMs. This makes the NC-coated AN technology a promising one that needs to be further developed in the future.
