“…For instance, the tensile strength of NR-based composites filled with 30 phr BT/TA-Fe III /Ag nanoparticles is 4.83 MPa, which is 1.5 times of NR-based composites filled with pristine BT nanoparticles at the same filler content. The higher tensile strength of BT/TA-Fe III /Ag/NR composites could be explained as follows: (i) the coating of TA improved the interfacial compatibility and interaction between BT/TA-Fe III /Ag nanoparticles and the NR matrix; (ii) the ortho-quinone groups, which could be originated from oxidized ortho-polyphenols of TA, could build a cross-linked structure by reacting with an accelerator complex and sulfur during rubber processing . We supposed that the TA on the surface of BT nanoparticles was bonded chemically on the rubber chains during rubber processing and bridged between fillers and rubber .…”

Dielectric elastomer actuators (DEA) were widely applied in the field of sensors, artificial muscles, and microrobotics as they can convert electrical energy into mechanical energy. In this work, we have designed strawberry-like barium titanate/tannic acid-ferric ion/silver (denoted as BT/TA-FeIII/Ag) dielectric nanoparticles to improve the electromechanical performance of natural rubber (NR)-based composites. In the first instance, BT nanoparticles were modified by TA by introducing catechol- and pyrogallol-type phenols, which can be complexed with FeIII to form a coating of TA-FeIII on the surface of the BT nanoparticles (denoted as BT/TA-FeIII). Then, Ag nanoparticles were deposited on the surface of BT/TA-FeIII by the reduced Ag+ via an electroless plating method. The addition of BT/TA-FeIII/Ag nanoparticles in the NR matrix enhanced the electromechanical sensitivity of NR-based composites and thus increased the actuation strain of NR-based composites. In addition, the discontinuous silver layer deposited on the surface of BT/TA-FeIII/Ag nanoparticles maintained good insulation of NR-based composites. In the final step, a high actuation strain (15.3%) was achieved by NR-based composites filled with 10 phr BT/TA-FeIII/Ag at a low electrical field (62.2 kV/mm), which was about 2.2 fold larger than the actuation strain of the pure NR (about 7.0% at 54.7 kV/mm). Overall, this strategy could provide insights for the preparation of dielectric elastomers with high actuation strain driven by a low voltage.

“…The ferrocene group in AEFC slightly decreased the surface tension of PAN-b-P(HEA-g-AEFC) with the value of ∆γ = 5.28 mN/m, suggesting a weaker interaction. Zhao et al [99] measured the contact angle of AP particles by the Washburn method and calculated the adhesion work between the AP and MAPO/HTPB matrix by OWRK. With the key parameters of critical debonding displacement calculated from the adhesion work, they successfully constructed a finite element model for the meso-debonding of the composite propellant interface.…”

Bonding agents are an important type of additive that are used to increase the interfacial interaction in propellants. A suitable bonding agent can prevent the dewetting between the oxidant and binder, and thus effectively improve the mechanical properties of the propellant. In the current paper, the bonding mechanisms and research progress of different types of bonding agents such as alcohol amine bonding agents, borate ester bonding agents, aziridine bonding agents, hydantoin bonding agents, neutral polymer bonding agents, and so on, are reviewed and discussed. The evaluation methods of their bonding performances including molecular dynamic simulation, contact angle method, in situ loading SEM, characterization analysis, and mechanical analysis are summarized to provide design ideas and reference for future studies.

“…The application of GAP in energetic solid propellants for missile weapon systems was considered in conjunction with two different explosive materials: ionic 5,5'-bistetrazole-1,1'-diolate (TKX-50) [88], whose application is relatively novel in the field, and one of most commonly used non-ionic explosive cyclotetramethylenetetranitramine (HMX) [89]. The binding energy between GAP and TKX-50 (Figure 12) is larger than for GAP and HMX (163.35 kcal/mol and 148.98 kcal/mol, respectively), indicating stronger interactions between GAP and the crystalline surface of TKX-50 than between GAP and HMX.…”

Glycidyl azide polymer (GAP), an energetic binder, is the focus of this review. We briefly introduce the key properties of this well-known polymer, the difference between energetic and non-energetic binders in propellant and explosive formulations, the fundamentals for producing GAP and its copolymers, as well as for curing GAP using different types of curing agents. We use recent works as examples to illustrate the general approaches to curing GAP and its derivatives, while indicating a number of recently investigated curing agents. Next, we demonstrate that the properties of GAP can be modified either through internal (structural) alterations or through the introduction of external (plasticizers) additives and provide a summary of recent progress in this area, tying it in with studies on the properties of such modifications of GAP. Further on, we discuss relevant works dedicated to the applications of GAP as a binder for propellants and plastic-bonded explosives. Lastly, we indicate other, emerging applications of GAP and provide a summary of its mechanical and energetic properties.
