To develop advanced cellulose-based energetic composites, new types of high-energy-density formulations containing hydrazine 3-nitro-1,2,4-triazol-5-one (HNTO)/ammonium nitrate (AN) cocrystals combined with nitrocellulose or nanostructured cellulose (NC and NMCC) were experimentally characterized. The prepared analyzed in terms their physicochemical properties, mechanical sensitivities, structural features, thermal behavior. Their heats combustion theoretical performance assessed as well. Experimental results exhibited the inherent characteristics designed NC@HNTO/AN NMCC@HNTO/AN, including improved density, specific impulse, impact sensitivity compared to raw compounds. Besides that, thermo-kinetic findings revealed that as-prepared insensitive composites undergo two exothermic decomposition processes, has higher activity. present study demonstrated outstanding could serve a reference for developing more formulations.

This research work aimed to elaborate on a new modified double-base propellant containing nitrocellulose (NC), ammonium nitrate (AN), and diethylene glycol dinitrate (DEGDN). The developed AN/NC-DEGDN formulation was successfully obtained through casting process fully characterized in terms of its chemical structure, morphological features, thermal behavior. Beforehand, theoretical calculation by the CEA-NASA program applied select optimal composition formulation. Experimental findings demonstrated homogenous dispersion AN oxidizer NC-DEGDN matrix without alteration their molecular structures. catalytic influence decomposition behavior film also elucidated analyses. When incorporated into formulation, peak temperatures for different processes were shifted toward lower temperatures, while total enthalpy increased around 1272.24 J/g. In addition, kinetics double base investigated using DSC results coupled with model kinetic approaches. It found that addition decreases activation energy esters from 134.5 kJ/mol 118.84 kJ/mol, providing evidence excellent effect. Overall, this investigation could serve as reference developing future generation propellants.

The mild and simple direct organocatalytic esterification of cellulose nanocrystals (CNC) nanocellulose-based materials (e.g. foams films) with thioglycolic acid (TGA) is disclosed. transformation gives the corresponding thiol group (-SH) functionalized crystalline nanocellulose (CNC-SH) using simple, naturally occurring, non-toxic organic acids tartaric acid) as catalysts. We also discovered that TGA autocatalytic (i.e. catalyzing its own esterification). introduction -SH functionality at surface opens up for further selective applications. This was demonstrated by attaching catalysts fluorescent molecules, which are useful sensors, to CNC-SH thiol-ene click chemistry. Another application use CNC-SH-based foam a heterogeneous biomimetic reducing agent, stable during multiple recycles, copper-catalyzed alkyne-azide 1,3-dipolar cycloaddition ("click" reaction).

Energetic binders, essential components of energetic materials (EMs), act as the main support for energy and mechanical properties propulsion. Compared with conventional nitrocellulose (NC), two nitrated bacterial cellulose (NBC) nitrate glycerol ether (NGEC), exhibit promising applications in enhancing strength propulsion due to their inherent physicochemical features. Herein, we present a series characterizations methods study structures NC, NBC, NGEC by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, Raman photoelectron spectroscopy (XPS). More importantly, thermal analysis was performed under four universal heating conditions: programmed, constant temperature, high pressure, adiabatic. It found that NBC exhibited higher stability activation (Ea) iso-conversional rate kinetic analysis, including Friedman, Vyazovkin, Ozawa–Flynn–Wall (OFW), Kissinger–Akahira–Sunose (KAS) methods. Under high-pressure conditions, decomposition reaction NC promoted increased pressure range 0–3 MPa, such decreased whereas stability. adiabatic it presented than can produce more gases generate less time. be concluded binders different exert various effects. Hence, results this work on may offer fundamental theory data supporting future formulas.
