Jem 100s transmission electron microscope

UV–Vis spectra were recorded on Shimadzu 2040 instrument. Fourier transforms infrared (FTIR) spectrometer (VERTEX 70 F T-IR) spectra were measured in ATR discs at room temperature within the wavenumber range of 400–4000 cm⁻¹. Bruker high-performance digital FT-NMR spectrometer Avance III 400 MHZ was employed to perform routine ¹H/¹³C high–resolution spectra along with common 2D experiments (COSY, HMBC, HSQC, …). The crystalline structure of prepared polymers was checked by X-ray diffraction (2,020,964 PA Analytical Empyrean). A scanning electron microscope (SEM; JEOL (JSM-5200)) was employed to investigate the morphologies of the prepared polymers. Samples were prepared by placing a slight part of a film on a carbon tube on a stub, which was coated with a gold thin layer. Micrographs of the prepared new polymeric materials using a JEM-100S Transmission Electron Microscope (TEM, Jeol, Tokyo, Japan) were taken. The different area pictures were captured at adjustable magnifications that identify the particle size and morphology. TGA-50H thermogravimetric analyzer was used to study the thermal stability of synthesized polymeric materials. Samples were heated from 10 to 600 °C in a platinum pan with a heating rate of 10 °C min⁻¹ under an N₂ atmosphere with a flow rate of 25 mL min⁻¹.
