Synergistic combination of multi-level hydrogen bonds and disulfide to construct high-strength, rapid self-healing polyurethane elastomers.
The introduction of weak hydrogen bonds based on the isophorone structure enables polymer to have high stretchability and self-healing ability at room temperature heal propellant damage.
Ammonium perchlorate (AP), a widely used oxidizer in solid propellants, requires the incorporation of combustion catalysts to enhance its thermal decomposition efficiency. However, such modifications often compromise safety performance. Inspired...
A high self-healing efficient HTPB-based adhesive containing disulfide bonds, which can improve propellant interface debonding defects at a safe temperature.
Abstract Self‐healing performance of materials can greatly improve the life and reduce their maintenance costs. Therefore, preparation self‐healing coating is expected to be development trend materials. In this paper, thermosetting polyurethane material (HTPB‐PG‐SS‐TDI) designed with excellent mechanical performance, thermal stability, acid–base resistance property, capability by introducing SS (4,4‐dihydroxy diphenyl dithioether) into chain. Maximum stress up 2.65 MPa, strain reach 700%....
In this study, we successfully manufactured polyurethane microcapsules containing isocyanate prepolymer as a core material for self-healing protection coatings via interfacial polymerization of commercial curing agent (Bayer L-75) and 1,4-butanediol (BDO) chain extender in an emulsion solution. With optical microscope (OM) scanning electron (SEM), the resulting showed spherical shape ideal structure with smooth surface. Fourier transform infrared spectra (FTIR) that was encapsulated. Thermal...
Abstract To improve the safety of HMX, HMX/TATB composite particles were prepared using a mechanochemical approach. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT‐IR) and X‐ray diffraction (XRD) employed to characterize HMX before after being coated. The results showed that coated by submicrometer‐sized TATB particles. crystal form maintained unchanged during whole preparing process. decomposition characteristics investigated DSC, showing peak temperature...
Herein, we report a novel polymerized complex method for preparation of Ni–Pd, Ni–Pt, Cu–Pt alloy, Pt, Pd, Ag, Ni, Cu nanoparticles. The grain sizes and crystalline phases these nanoparticles can be controlled.
Developing an autonomous self-healing polyurethane (PU) elastomer with excellent mechanical properties and high ductility has attracted increasing attention. Nowadays, the synthesis of elastomers rapid at room temperature faces a huge challenge. Herein, This work reports new supramolecular PU through introduction T-type chain extender into polymer chain. The T-chain can be used to enhance strength PU, multiple hydrogen bonds on side-chain provide theoretical support for ability PU. Maximum...
