Novel Approaches to In-Situ ATR-FTIR Spectroscopy and Spectroscopic Imaging for Real-Time Simultaneous Monitoring Curing Reaction and Diffusion of the Curing Agent at Rubber Nanocomposite Surface

Here, we propose a novel attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy method for simultaneously monitoring the curing reaction and diffusion behavior of agents at surface rubber in real-time. The proposed scheme was demonstrated by fluorine (FKM) FKM/carbon nanotube (CNT) nanocomposites with target agent triallyl-isocyanurate (TAIC). broadening evolution C=O stretching TAIC were quantitatively analyzed to characterize diffusion. Changes width indicated rate even faster than that bulk as measured curemeter. coefficient course heating newly calculated initial increase absorbance our model based on Fickian coefficients during evaluated, its temperature filler dependency identified. Cross-sectional ATR-FTIR imaging situ measurements supported hypothesis unidirectional towards heated surface. It shown can monitor degrees cure simultaneously, which cannot be achieved conventional methods, e.g., rheological measurements.
