FTIR spectra of carbon-based polymer materials (pristine fullerenes, nanostructures, and diamond-like C60 forms) were studied in the range from 1600 to 300 cm1.The micro-Raman spectra of the carbon-based materials and their new forms obtained under the conditions of high energy impacts allowed ...
1988. FTIR spectra of milled wood lignins and lignin polymer models (DHP's) with enhanced resolution obtained by decon- volution. J Wood Chem Technol 8:505-522.O. Faix and O. Beinhoff, FTIR spectra of milled wood lignins and lignin polymer models (DHP's) with enhanced resolution obtained...
Conclusions The composition an unknown polymer sample can be easily characterized by means of combined TGA/DSC-FTIR measurements. Table 1 summarizes the results obtained from the TGA measurement and the IR spectra for the particular sample investigated. The polymers in the unknown material were identif...

In order to obtain the independent variables consisting the input, the samples were examined by Thermogravimetric Analysis and Differential Thermal Analysis TGA/DTG, and FTIR spectra. Large-scale fire tests were not conducted, and the sample size were as small as a few milligrams to perform TGA ...
Figure 3. FTIR spectra of ATP and PPy/Ag/ATP nanocomposite (S-3). note that the N/Ag atomic ratio gradually decreased with increasing feeding concentration of ATP, although the initial feeding ratio of pyrrole/AgNO3 was kept as a constant (Table 2). Electrical conductivity. The ...
The optical properties of polymer coatings in mid-IR region are characterized by Fourier-transform infrared (FTIR) spectrometer (Nicolet 6700, Thermo Scientific) with an integrating sphere (Mid-IR IntegratIRTM, Pike Technologies). The emissivity is calculated based on the sum of the transmissivity,...
(ATR-FTIR) confirmed that the molecular weight and chemical composition of TPU did not change following HME, nor did the additional sample preparation steps for the water contact angle analysis impact polymer composition (Supplementary Figs.12and13). The Young’s modulus of BC TPUs was not ...
Fourier transform infrared spectroscopy (FTIR) indicated that these hybrid polymers are held together by electrostatic, H-bonding, and pi–pi interactions. The circular dichroism spectra of the hybrid polymers indicated that the dsRNA underwent a small distortion in conformation from the canonical A-...
In the case of black coloured samples, plastic components, fillers and reinforcement can be identified by using an attenuated total reflection (ATR) setup during Fourier transform-infrared (FTIR) spectroscopy. Raman spectra and mapping are another solutions to receive information about contaminants. ...
