Tg 209 f1

The crystal structures were characterized by X-ray diffraction analysis (XRD Rigaku D-max-γA XRD with Cu K_α radiation, λ = 1.54178 Å). Field-emission scanning electron microscopy (FE-SEM; JM 6700F), and transmission electron microscope (TEM; JEM-2100Plus, JEOL Ltd., Tokyo, Japan) were used to investigate the morphology and microstructure of the as-obtained F-FeS and B-FeS. Thermogravimetric (TG) analysis was measured on a TG apparatus (NETZSCH TG 209-F1, NETZSCH-Gerätebau GmbH., Selb, Germany) in the temperature range of 25–900 °C at a ramp of 10 °C min⁻¹ in air. The Brunauer–Emmett–Teller (BET) method was utilized to investigate the specific area by N₂ adsorption–desorption isotherms. To further characterize the chemical composition, XPS analysis was performed with X-ray photoelectron spectroscopy (Thermo ESCALAB 250XI, Thermo Fisher Scientific Inc., Waltham, MA, USA). Raman spectra was also performed to investigate the existence of carbon.

All chemical reagents were purchased in analytical grade. IR were recorded on Bruker ALPHA infrared spectrometer by using attenuated total reflection (ATR) mode. ¹H and ¹³C NMR spectra are recorded by Bruker AVANCE III HD with magnetic intensity 9.4 T and resonance frequency of 400 MHz and 100 MHz respectively. The samples are dissolved in locking solvent d₆-DMSO and their chemical shifts are analyzed and recorded in ppm by compared with the internal standard tetramethylsilane (TMS). Differential scanning calorimetry (DSC) test were taken on TA Q20 calorimeter with nitrogen as shield gas and indium as standard. The temperatures were recorded from −80 °C to 400 °C in a heading speed of 10° min⁻¹. Thermogravimetric analysis (TGA) were finished on NETZSCH TG 209F1 with nitrogen as shield gas of 70 mL min⁻¹ and heating from 25 to 500 °C at 0.1 MPa in 10 °C min⁻¹ Hydrogen, carbon and nitrogen elemental analyses is finished by Elementar Vario MICRO CUBE instrument. Schimadzu-xrd-6100 recorded PXRD data from 5° to 80 ° in a rate of 0.2°/min. Microscopic morphologies of the TATB were taken by HLP-85C polarizing microscope. The SEM test were obtained by Hitachi TM3000. Sensitivity were test by BCJ drop hammer testing machine and BMC friction testing machine.

Thermogravimetric analyses (TGA) of the cured materials were carried out to determine the thermal stability and were performed on a Netzsch TG 209F1 apparatus (Netzsch Holding, Selb, Germany) under 40 mL.min⁻¹ nitrogen flow. The protective gas used was nitrogen with a 20 mL.min⁻¹ flow. Approximately 10–12 mg of sample were placed in an alumina crucible and heated from room temperature to 800 °C with a 20 °C.min⁻¹ heating rate.

The synthesized composites were characterized using the following techniques: (1) Attenuated Total Reflection-Fourier Transform Infrared Spectroscopy (ATR-FTIR, 4000–500 cm⁻¹, Bruker TENSOR27, German); (2) X-ray Diffraction Analysis (XRD, PANalytical, the Netherlands) using the X'Pert Pro diffractometer with a Cu Kα radiation source (scanning amplitude = 5°–80°, scanning rate = 2° min⁻¹); (3) Thermogravimetric Analysis (TGA, TG209F1, Netzsch, Germany), performed under a N₂ atmosphere in the range of 50–800 °C; (4) X-ray Photoelectron Spectroscopy (XPS, KRATOS, XSAM800, Britain), performed using an EscaLab 250 Xi X-ray photon–electron spectrometer with monochromatic Al Kα X-rays adopted as the excitation source and the C 1s peak used to check the energy scale; (5) Scanning Electron Microscopy (SEM); and (6) Transmission Electron Microscopy (TEM). The surface morphology and structure of the materials were observed via SEM (JSM-7500 F, JEOL, Tokyo, Japan) after being coated with 10 nm-thick Aurum, and subsequently via TEM (Tecnai G2F20, USA).

Thermogravimetric analysis
(TGA) curves were recorded under a reconstituted air atmosphere (20%
O₂ and 80% N₂) with a heating rate of 10 K·min^–1 (TG 209 F1, Netzsch).

TGA was performed using a TG 209 F1 (Erich NETZSCH GmbH & Co, Selb, Germany) setup in a temperature range from 30 to 600 °C, again at a 10 °C·min⁻¹ heating rate, in argon medium. The sample mass was 2–3 mg.
DSC analysis of the samples was carried out using a DSC 204 F1 (Erich NETZSCH GmbH & Co, Selb, Germany) heat flow differential scanning calorimeter in a temperature range from 30 to 250 °C in an argon atmosphere; the heating rate was 10 °C·min⁻¹.
A DMA 242 C setup (Erich NETZSCH GmbH & Co, Selb, Germany) was used to measure the temperature dependence of the dynamic mechanical characteristics of the films during stretching (Young’s modulus E’, loss modulus E”, and mechanical loss tangent tgδ). The measurements were carried out at a frequency of 1 Hz and a heating rate of 5 °C·min⁻¹. The temperatures of the relaxation transitions were determined from the positions of the maxima or from inflexions of the curves for dynamic parameters.
The X-ray diffraction analysis was performed using a Miniflex 600 (Rigaku Technologies, Inc., Tokyo, Japan) diffractometer (U = 40 kV, J = 15 mA, and a range of angles 2θ from 5 to 50).
Cross-sectional images of the films were taken on a Scios scanning electron microscope (Field Electron and Ion Company, Hillsboro, OR, USA) with a FEG electron source.
