“…CNs have acquired particular importance in disease diagnostics and treatment due to their microporous structure and strong affinity for interacting with and subsequently absorbing a biomaterial (for example, antibodies) [ 2 , 3 , 4 ]; antiCOVID-19 masks [ 5 ] and composite filter membranes for oligonucleotide extraction [ 6 , 7 ] have emerged. The energetic properties of CNs are in demand as constituents of explosive compositions [ 8 , 9 , 10 , 11 ] in the mining industry, road construction in mountainous areas, and focused demolition of obsolete structures because the safety and handling issues associated with CN-based compositions have currently been resolved at a very high level [ 12 ]. It should be emphasized that CNs themselves have become precursors of more complex chemicals with unique energetic characteristics [ 13 ].…”

This study is focused on exploring the feasibility of simultaneously producing the two products, cellulose nitrates (CNs) and bacterial cellulose (BC), from Miscanthus × giganteus. The starting cellulose for them was isolated by successive treatments of the feedstock with HNO3 and NaOH solutions. The cellulose was subjected to enzymatic hydrolysis for 2, 8, and 24 h. The cellulose samples after the hydrolysis were distinct in structure from the starting sample (degree of polymerization (DP) 1770, degree of crystallinity (DC) 64%) and between each other (DP 1510–1760, DC 72–75%). The nitration showed that these samples and the starting cellulose could successfully be nitrated to furnish acetone-soluble CNs. Extending the hydrolysis time from 2 h to 24 h led to an enhanced yield of CNs from 116 to 131%, with the nitrogen content and the viscosity of the CN samples increasing from 11.35 to 11.83% and from 94 to 119 mPa·s, respectively. The SEM analysis demonstrated that CNs retained the fiber shape. The IR spectroscopy confirmed that the synthesized material was specifically CNs, as evidenced by the characteristic frequencies of 1657–1659, 1277, 832–833, 747, and 688–690 cm−1. Nutrient media derived from the hydrolyzates obtained in 8 h and 24 h were of good quality for the synthesis of BC, with yields of 11.1% and 9.6%, respectively. The BC samples had a reticulate structure made of interlaced microfibrils with 65 and 81 nm widths and DPs of 2100 and 2300, respectively. It is for the first time that such an approach for the simultaneous production of CNs and BC has been employed.

“…This way, the blended CNs are more thermostable compared with CN OHC, while already having a reticulate nanostructure. This allows the properties of CNs to be improved and their application area to be expanded for use as an energetic gel matrix, basic gunpowder ingredient, selective sorbents, biosensors, semipermeable membranes, chips, bioindicators, ionizing radiation detectors, and adhesives for electronic applications [7,36,43]. CN BC is an excellent additive to achieve more promising energetic properties, in particular a higher nitrogen content with a stable nanostructure and an improved thermal stability, while the addition of CN OHC can even make the CNs-blended composite cheaper.…”

“…Research on the synthesis of energetic composites is gaining relevance. For instance, previous studies [43,44] synthesized CN/nitrochitosan-blended energetic composites and demonstrated that the components have a positive interplay in the composite. It should be noted that the cellulose and chitosan were nitrated separately in those studies, and the nitrates were then blended to obtain composites through solubilization and drying.…”

Cellulose nitrates (CNs)-blended composites based on celluloses of bacterial origin (bacterial cellulose (BC)) and plant origin (oat-hull cellulose (OHC)) were synthesized in this study for the first time. Novel CNs-blended composites made of bacterial and plant-based celluloses with different BC-to-OHC mass ratios of 70/30, 50/50, and 30/70 were developed and fully characterized, and two methods were employed to nitrate the initial BC and OHC, and the three cellulose blends: the first method involved the use of sulfuric–nitric mixed acids (MAs), while the second method utilized concentrated nitric acid in the presence of methylene chloride (NA + MC). The CNs obtained using these two nitration methods were found to differ between each other, most notably, in viscosity: the samples nitrated with NA + MC had an extremely high viscosity of 927 mPa·s through to the formation of an immobile transparent acetonogel. Irrespective of the nitration method, the CN from BC (CN BC) was found to exhibit a higher nitrogen content than the CN from OHC (CN OHC), 12.20–12.32% vs. 11.58–11.60%, respectively. For the starting BC itself, all the cellulose blends of the starting celluloses and their CNs were detected using the SEM technique to have a reticulate fiber nanostructure. The cellulose samples and their CNs were detected using the IR spectroscopy to have basic functional groups. TGA/DTA analyses of the starting cellulose samples and the CNs therefrom demonstrated that the synthesized CN samples were of high purity and had high specific heats of decomposition at 6.14–7.13 kJ/g, corroborating their energy density. The CN BC is an excellent component with in-demand energetic performance; in particular, it has a higher nitrogen content while having a stable nanostructure. The CN BC was discovered to have a positive impact on the stability, structure, and energetic characteristics of the composites. The presence of CN OHC can make CNs-blended composites cheaper. These new CNs-blended composites made of bacterial and plant celluloses are much-needed in advanced, high-performance energetic materials.

“…Understanding the thermal decomposition characteristics of the energetic binder is crucial, as it provides valuable information regarding its safety and potential impact on the overall performance of the propellant. 42,43 As shown in Figure 6a−c, there is one prominent exothermic peak ranging from 253 to 261 °C when subjected to a heating rate of 10 °C/min in DSC, 15,16,28,37 demonstrating that the energetic binder exhibits good thermal stability, similar to that of the random copolymer. 12 The T p values of the copolymers are primarily influenced by the content of EG and THF.…”

In the field of energetic materials (EMs), soft chains are copolymerized with energetic polymers to improve flexibility. However, this often makes it difficult to achieve simultaneous optimization of the energy level and flexibility due to the random sequence. In this study, a simple approach is presented to develop energetic sequencecontrolled polymers (ESCPs), alternate copolymers poly(3,3-bis(azidomethyl)oxetaneglycol) (P(BAMO-alt-EG)) and poly(3,3-bis(azidomethyl)oxetane-tetrahydrofuran) (P(BAMO-alt-THF)), through click reactions. This approach provides the potential to design and control mechanical and thermal properties in propellant binders by introducing various segments and regulating the sequence structure. These polymers display excellent thermal stability and demonstrate that regulated shorter segmental length promoted better flexibility and less residual carbon content without compromising the energy level of the propellant. The obtained kinetic parameters prove that P(BAMO-alt-EG) released higher heat and accelerated the thermolysis process compared to P(BAMO-alt-THF). These results demonstrate the potential of highly alternating ESCPs as a potential energetic propellant binder.
