Characterization of PEGDA-AESO Copolymers

Check if the same lab product or an alternative is used in the 5 most similar protocols

Fourier-transform infrared spectroscopy (FTIR) was used to confirm the formation of PEGDA:AESO copolymers at different ratios and to monitor the conversion of the acrylic double bonds. The infrared analysis was performed using a Thermo Avatar 370 spectrophotometer equipped with an attenuated total reflectance (ATR) device with a diamond crystal for solid analysis. Using Omnic 7.3 software, the spectra were collected in absorbance mode with a resolution of 4 cm⁻¹ and 32 scans per measurement, within the range of 2000 to 650 cm⁻¹, using 3D-printed dog-bone specimens. The conversion of double bonds was calculated from the decrease in the area of the double-bond absorption peak at 810 cm⁻¹, as shown by Equation (2).

Conversion (%) = (1 - \frac{A_{t (810)}}{A_{0 (810)}}) \times 100 %,

where A₀₍₈₁₀₎ and A_t(810) are the areas of the peak at 810 cm⁻¹, before and after exposure to UV irradiation, respectively.

HAP was characterized using optical microscopy, SEM, and FT-IR. Electron microscopy was completed using a Zeiss EVO LS10 microscope operated at 2.0 kV. FT-IR spectra were combined from 64 scans on a Thermo Nicolet Avatar 370 with a diamond crystal Smart iTR attachment. QCM crystals were prepared as above. Surface roughness of spin-coated HAP was determined by AFM (Bruker Nanoscope III multimode, Santa Barbara, CA) in contact mode with a SiN₄ cantilever. Surface area measurements were obtained using the instrument’s accompanying analysis software.

Morphology and size distribution of nanoparticles were evaluated using transmission
electron microscope (TEM) (Gatan model 791, Philips CM 12, Poland) and image J,
respectively. X-ray Diffraction (XRD) patterns of dried nanoparticle powders were analyzed
through the GNR EXPLORER (XRD) X-ray diffraction gauge with a wavelength of 1.54 Å
K_a lines. Fourier Transform Infrared (FTIR) spectra were evaluated using an
infrared spectrometer Red (AVATAR 370, Thermo Nicolet AVATAR 370 FTIR, USA). The surface
charge of nanoparticles and the hydrodynamic size of nanoparticles were measured by a
device (SZ100, HORIBA, Japan). The contents of bismuth in the samples were measured using
Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES) (VISTA-MPX, Varian
Inc., USA).

The infrared spectrum of absorption or emission of a matter was determined using Fourier transform infrared spectroscopy (FTIR) (Thermo Nicolet, Avatar 370). At first, the films were powdered to set up the discs, and then 70 mg of spectroscopic grade KBr was mixed fully with roughly 2 mg of the film's powder. Subsequently, the powder was hard‐pressed into pellets to obtain a transparent disc with 15 mm in diameter and 0.54 mm thickness. The FTIR spectra were obtained in the 4000–400 cm⁻¹ range, at 25°C, by co‐adding 32 scans with 4 cm⁻¹ spectral resolution.

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.
