To determine the functional groups and successful composite formation, the Spectrum II spectrometer (Perkin-Elmer, Johannesburg, South Africa) was operated at room temperature with a resolution of 4 cm−1 and a range of 4000–400 cm−1. The absorption studies were performed with the Varian Cary 300 UV-vis-NIR spectrophotometer (Agilent, Santa Clara, CA, USA), in the range 250–800 nm. The structures of PABA, CoZIF and the PABA/CoZIF composite were analyzed with the aid of X-ray diffraction (XRD, Phillips PW 1830, Eindhoven, The Netherlands) using the Cu-Kα radiation with λ = 1.5406 Å.
The thermal stabilities of the prepared materials were deduced using a simultaneous thermal analyzer (STA) 6000 from Perkin-Elmer (Johannesburg, South Africa), which was operated at a rate of 20 mL/min in purged N2 gas with heating from 30 to 500 °C at 10 °C/min.
The morphological characteristics of the prepared samples were determined by Auriga field emission scanning electron microscopy (FE-SEM), with an instrument from Carl Zeiss Microscopy GmbH (Jena, Germany) coupled with an energy dispersive X-ray spectrometer (EDS), and transmission electron microscopy (TEM) (FEI Tecnai G2 F20X-Twin MAT 200 kV Field Emission Transmission Electron Microscope) (Eindhoven, The Netherlands).

Unless otherwise
indicated, operations were performed under anhydrous and anaerobic
conditions (a dry nitrogen atmosphere), using standard Schlenk line
and glovebox (MBraun Labstar Pro) techniques. Glassware was dried
in an oven at 160 °C prior to use. NMR spectra were acquired
using a Bruker Avance III 400 MHz spectrometer. Infrared spectra data
were recorded on a PerkinElmer Spectrum 2 spectrometer, with the samples
as neat solids, in attenuated total reflectance (ATR) mode. UV–visible
spectra were obtained in acetonitrile solution in gastight cuvettes
(path length 1.2 cm) on a Shimadzu UV-2600 spectrometer. Magnetic
susceptibility measurements were performed using a Sherwood Scientific
MK 1 magnetic susceptibility balance. Elemental analysis was performed
by Galbraith Laboratories, Inc. (Knoxville, TN). Nondeuterated solvents
were deoxygenated by sparging with dry nitrogen and then dried via
passage through activated alumina in an MBraun MB-SPS solvent purification
system. CD3CN was degassed via the freeze–pump–thaw
method and dried over activated 4 Å molecular sieves. Reagents
were obtained from commercial suppliers (Sigma-Aldrich, Fisher, Strem,
TCI) and used without further purification.

With a Perkin Elmer Spectrum-2 spectrometer, the FT-IR spectra of theSWHC and PWHC were recorded across a range of 4000 cm−1 to 400 cm−1, using the attenuated total reflection (ATR). The spectrum was obtained after 24 consecutive scans. The JEOL-JSM-6390 scanning electron microscope was used to examine the surface morphological properties of the hybrid composites. The samples were sputter coated with gold-palladium to prevent electron beams from having any charge effects during the examination. The images were captured at various magnifications at a 20 kV accelerating voltage. The thermogravimetric analysis was carried out, using TA instruments (SDT Q600) in an inert atmosphere at temperatures ranging from 25 °C to 700 °C. The heating rate, 10 °C/min and a DTA sensitivity of 0.001 °C were maintained throughout the analysis. The composite samples were subjected to accelerated aging to temperature (ASTMD 573-04), UV, and biodegradation as per the standard methods reported in our previous studies [22 (link)].

Synthesis of SeNPs was first detected by the formation of brick red coloured colloids in the reaction mixture, then scanning the solution by using a UV-Visible spectrophotometer (Thermo Scientific Multiscan Go) in the wavelength range of 250–700 nm. Fully dried purified SeNPs powder was used for the XRD (X-ray diffraction) analysis by X'Pert Pro Powder X-ray diffractometer operated at voltage 40 kV, current 40 mA with Cu-Kα radiation (K = 1.5436Å), for 2θ = 5°C–80 °C to determine the crystalline properties and purity of the green synthesized nanoparticles. SeNPs powder was ground with KBr to make pellet and analysed by FTIR Spectrophotometer (PerkinElmer Spectrum 2 Spectrometer) in the spectral range of 4000-400 cm−1 to determine the functional groups attached to the surface of the SeNPs. SeNPs were then coated with gold to determine the morphology and percentage purity by Scanning Electron Microscope (Sigma 300, Zeiss) coupled with Energy Dispersive X-ray Spectroscopy (EDAX-element). Nanoparticles were dispersed in distilled water and sonicated (by Hielscher ultrasonic processor, UP200Ht) to determine the particle size distribution and average particle size through DLS (Dynamic Light Scattering) technique by using Zeta Sizer (Malvern, Nano-s90).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
