Order–order, lattice disordering, and order–disorder transition in SEBS studied by two-dimensional correlation infrared spectroscopy

Green solvent approach for printable large deformation thermoplastic elastomer based piezoresistive sensors and their suitability for biomedical applications

“…The FTIR spectra for neat SEBS and for the MWCNT composites are shown in Figure (E), where the typical absorption bands for SEBS are identified, such as the styrene block at 699 cm −1 that characterize the aromatic ring of the CH group, and the CH stretching at 2852 and 2923 cm −1 for the ethylene/butylene block . There are no significant differences between the spectra of neat SEBS and the MWCNT/SEBS composites, indicating that no covalent bonds are formed between SEBS and the MWCNT …”

On the use of surfactants for improving nanofiller dispersion and piezoresistive response in stretchable polymer composites

“…The FTIR spectra for the different CNT/SEBS composites with TX-100 surfactant are presented in Figure 2. The typical absorption bands of SEBS can be identified at 699 cm -1 for the =C-H bending vibration of the aromatic ring of the styrenic block and at 2850 and 2925 cm -1 for the C-H asymetric and symetric stretching vibrations of the -CH2-of the ethylene/butylene block chain, respectively 29,34 .…”

Cross-linking process of cis-polybutadiene rubber with peroxides studied by two-dimensional infrared correlation spectroscopy: a detailed tracking

“…[21][22][23] In general, PCMW2D was employed to determine the transition point and the transition range of polymers; then, generalized 2D spectroscopy was performed to study the mechanism of functional groups at a specic transition. [24][25][26][27][28][29] Many successful applications were reported in the study of the mechanism of polymer physical or chemical transitions. [30][31][32][33][34][35][36] In this study, the cross-linking process of cis-BR induced by peroxide is investigated by in situ FTIR spectroscopy combined with 2D correlation analysis.…”
