“…The appearance of D peak is related to the structural defects and partial disordered structure of sp 2 carbon atoms in Am-GO materials. The generation of G peak is related to the first-order scattering of E 2g phonon mode of sp 2 carbon atoms in Am-GO materials [28,[37][38]. The intensity ratio of D peak to G peak in Raman spectrum is considered as a measure of disorder, reflecting the relative disorder caused by structural defects [39].…”

The thermal decomposition of Hexanitrohexaazaisowurtzitane CL-20/HMXammonium formate functionalized graphene oxide (Am-GO) composites was studied using an isothermal decomposition dynamics research instrument to explore the effects of Am-GO on the stability of CL-20/HMX co-crystal. The gas pressure-time curve generated by thermal decomposition reaches the decomposition inflection point at a decomposition degree of 85 %. Compared with CL-20/HMX co-crystal, the decomposition extent corresponding to the inflection point of the thermal decomposition curve of the composites increases. The activation energies of the composites before and after the inflection point of the pressure-time curve were 161.3 kJ/mol and 171.0 kJ/mol, respectively. The residual substances produced by the thermal decomposition of the composites were characterized by HPLC and FTIR. Results showed that CL-20 and HMX were decomposed before the inflection point of the decomposition pressure-time curve. However, the decomposition of CL-20 was completed before the inflection point, whereas that of HMX ran through the thermal decomposition process. The calculation results of thermal decomposition kinetics show that the addition of coating material increases the activation energy of co-crystal and stabilizes CL-20/HMX co-crystal.

“…Their physical and chemical properties make them useful for a wide range of applications, including fibrillated aerogels, hydrogels, polymeric nanocomposites, insulating foam technology, biomedical uses, energy storage, and oil absorption. [ 58 ] Usually, cellulose monomeric units contain three highly reactive hydroxyl groups, which give cellulose higher chirality, hydrophilicity, and biodegradability. These hydroxyl groups can also be chemically modified in cellulosic derivatives because they can be easily functionalized ( Figure ).…”

MXenes have been highly attractive to researchers owing to their layered nanostructure, excellent electrical conductivity, and abundance of functional groups. Meanwhile, nanocellulose materials, known for their biodegradability, renewability, compatibility with living organisms, and cost‐effectiveness, have emerged as a popular choice for material selection researchers. Recent research has discovered that combining nanocellulose with MXenes can improve the mechanical properties of MXenes, resulting in composite materials with remarkable electrical and mechanical properties. This article provides an overview of the three main types of nanocellulose: cellulose nanofiber, cellulose nanocrystal, and bacterial cellulose. It also discusses various synthesis methods for MXenes, including MXene/nanocellulose‐based hydrogel and aerogel. Additionally, the article highlights the multiple uses of MXene/nanocellulose composites in different fields, including flexible sensing materials, electromagnetic shielding, energy storage structures, and wearable health monitoring. This review covers distinctive characteristics and unique MXene/nanocellulose composite behaviors, their recent advancements in MXene/nanocellulose synthesis, and applications. Moving forward, the potential for these materials to be used innovatively with anticipation of taking the MXene/nanocellulose‐based research further steps across the respective scientific community.

Nanocellulose can be obtained from low-cost sources and has been extensively studied in the last decades due to its biodegradability, biocompatibility, low weight, large specific surface area, and good mechanical and optical properties. The nanocellulose properties palette can be greatly expanded by incorporating different metals, metal oxides or carbon nanomaterials, with the formation of multifunctional hybrids. Nanocellulose–nanocarbon hybrids are emerging nanomaterials that can respond to many current challenges in areas such as water purification, energy storage and conversion, or biomedicine for drug delivery, tissue engineering, antitumor and antimicrobial therapies, and many others. Although nanocellulose–nanodiamonds hybrids are still in their infancy, these nanomaterials are extremely promising for applications requiring good thermal conductivity and mechanical strength along with optical transparency. A strong increase in the thermal conductivity of a nanocellulose film of about 150 times was obtained after the addition of 90 wt% single-crystal nanodiamonds and a 70% increase in the Young’s modulus of nanocellulose films was produced by the addition of 5 wt% nanodiamonds. Therefore, in this review, data related to the manufacturing routes, main properties, and applications of nanocellulose–nanodiamonds hybrids are presented and discussed. This review paves the way for new methods and procedures to obtain nanocellulose–nanodiamonds hybrids better adapted to practical needs.
