Siloxane adsorption on activated carbons: Role of the surface chemistry on sorption properties in humid atmosphere and regenerability issues
2019, Chemical Engineering JournalCitation Excerpt :The appearance of this band shows that other siloxane species are desorbing from the samples. Table 7 gathers the characteristic IR bands of different linear and cyclic (gas phase) siloxanes in the 1300–800 cm−1 region [37–40]. From data in Table 7, the band at 1035 cm−1 can be unambiguously attributed to the asymmetric Si-O-Si stretch vibration of D3.
Physico-chemical properties of PDMS surfaces suitable as substrates for cell cultures
2016, Applied Surface ScienceCitation Excerpt :Independently of the PDMS stiffness, the recorded infrared spectra do not show any significant differences in samples where the chemical bondings between benzophenone radicals and PDMS curing agent were formed. The observed bands were characterized for PDMS and were attributed as follows [65–67]. The band of wavenumbers of 2963 cm−1, 2904 cm−1 correspond to CH asymmetric deformation in SCH3 while the band of 1412 cm−1 is attributed to asymmetric bending in CH3 chemical groups [65].
Thermal stability and thermokinetics studies on silicone ceramer coatings: Part 1-inert atmosphere parameters
2009, Polymer Degradation and StabilityCharacterization of degradation products of poly[(3,3,3-trifluoropropyl)methylsiloxane] by nuclear magnetic resonance spectroscopy, mass spectrometry and gas chromatography
2009, Polymer Degradation and StabilityCitation Excerpt :Additionally, the negative ionization mode generally has the advantage of providing fewer background signals than the positive mode. GC coupled to a flame ionization detector (FID) or mass spectrometer was repeatedly employed for the quantification of cyclosiloxanes [38,41–44]. The FID is a perfect tool for this purpose, as it is very sensitive and quantitative for all members of a homologous series, as its response is proportional to the ring size.
