Chemical composition of the surface of modifying polymers in filled cellulose nitrate composites: An IR study

Supervision of Ethylene Propylene Diene M-Class (EPDM) Rubber Vulcanization and Recovery Processes Using Attenuated Total Reflection Fourier Transform Infrared (ATR FT-IR) Spectroscopy and Multivariate Analysis

“…However, analytical techniques often require individualized result interpretation, are often time-consuming, and entail the consumption of chemicals and reagents, thus increasing costs because laboratory-grade facilities and specialized technicians are required. 11,13–16…”

“…However, analytical techniques often require individualized result interpretation, are often time-consuming, and entail the consumption of chemicals and reagents, thus increasing costs because laboratory-grade facilities and specialized technicians are required. 11,[13][14][15][16] In contrast, chemometric multivariate analysis methods can be successfully applied to process control from spectral acquisitions in a nondestructive, fast, 17 and even real-time manner. Multivariate methods have been widely applied to determine the composition of polymer blends, [18][19][20][21][22] since they allow a more exhaustive interpretation of the infrared spectral data which allows determining and weighting the relative proportions of the components in an elastomeric blend.…”

Formation of triazole inhibitive film on copper surface by click assembly in presence of Cu2S quantum dots

“…The attenuated total reflection (ATR)–IR spectra for two assembled copper pieces are shown in Figure 3. The FT‐IR of Cu (TA + PA) shows the stretching vibration peak of N═N at 1356 cm −1 , indicating that the triazole ring is formed on copper surface 46 . The –N 3 peak at 2068 cm −1 increases obviously, suggesting that click reaction on copper surface is not fully reacted 47 .…”
