“…It is now understood that many developed anticancer drugs/prodrugs have poor solubility or stability, severe side effects, and limited self‐targeting capabilities, greatly decreasing their efficacies. [ 46–50 ] For example, PTX has been shown to exhibit good efficacy against lung, breast, and ovarian cancers. However, many limitations, e.g., poor solubility, drug resistance, and side effects on healthy tissues hinder its clinical application.…”

Chemotherapy is widely recognized as an effective approach for treating cancer due to its ability to eliminate cancer cells using chemotherapeutic drugs. However, traditional chemotherapy suffers from various drawbacks, including limited solubility and stability of drugs, severe side effects, low bioavailability, drug resistance, and challenges in tracking treatment efficacy. These limitations greatly hinder its widespread clinical application. In contrast, supramolecular chemotherapy, which relies host–guest interactions, presents a promising alternative by offering highly efficient and minimally toxic anticancer drug delivery. In this review, we provide an overview of recent advancements in supramolecular chemotherapy based on host–guest interactions. We emphasize the significant role it plays in guiding cancer therapy. Drawing on a wealth of cutting‐edge research, we aim to present a timely and valuable resource for individuals interested in the field of supramolecular chemotherapy or cancer therapy. Furthermore, we aspire to contribute to progression of the field of supramolecular chemotherapy toward clinical application.This article is protected by copyright. All rights reserved

“…In the domain of energetic materials (EMs), energetic binders play a vital role in supporting the energy and mechanical performances of propulsion, such as solid rocket propellants and gun propellants. − Therein, nitrocellulose (NC) is regarded as one of the most significant industrial materials because of its unique physical properties and is widely used in plastics, paints, lacquers, propellants, explosives, and so forth . Nevertheless, NC is derived from various plant fibers, which leads to the presence of some impurities, such as lignin, hemicellulose, pectin, starch, and other plant materials .…”

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

“…Polymer binder is one of the materials used for energetic composites, mainly for bonding and endowing materials with mechanical properties [ 7 ]. For balancing the mechanical properties and improving the reprocessing performance of energetic composites, substantial efforts have focused on the molecular engineering of polymers [ 8 , 9 , 10 ]. However, the ultra-high filler will inevitably reduce the interface contact effect, thus intensifying the contradiction between tensile strength, toughness and reprocessing.…”

Mechanical properties and reprocessing properties are of great significance to the serviceability and recyclability of energetic composites. However, the mechanical robustness of mechanical properties and dynamic adaptability related to reprocessing properties are inherent contradictions, which are difficult to optimize at the same time. This paper proposed a novel molecular strategy. Multiple hydrogen bonds derived from acyl semicarbazides could construct dense hydrogen bonding arrays, strengthening physical cross-linking networks. The zigzag structure was used to break the regular arrangement formed by the tight hydrogen bonding arrays, so as to improve the dynamic adaptability of the polymer networks. The disulfide exchange reaction further excited the polymer chains to form a new “topological entanglement”, thus improving the reprocessing performance. The designed binder (D2000-ADH-SS) and nano-Al were prepared as energetic composites. Compared with the commercial binder, D2000-ADH-SS simultaneously optimized the strength and toughness of energetic composites. Due to the excellent dynamic adaptability of the binder, the tensile strength and toughness of the energetic composites still maintained the initial values, 96.69% and 92.89%, respectively, even after three hot-pressing cycles. The proposed design strategy provides ideas for the design and preparation of recyclable composites and is expected to promote the future application in energetic composites.
