Abstract Scope Crystallinity significantly influences the mechanical, thermal, and chemical properties of polymers. However, real-time detection of crystallinity remains challenging because conventional methods are often unsuitable for in situ measurements. This study presents a fast, AI-based combined experiment-simulation approach for measuring crystallinity using Raman and Terahertz Time-Domain Spectroscopy (THz-TDS). Raman spectra analyze surface chemistry, while THz-TDS assesses the bulk response of thermoplastic polyurethane and nylon with varying degrees of crystallinity. Dimensionality reduction was applied to Raman spectra and the magnitudes and phases of THz spectra. The extracted features were then used to train a deep neural network (DNN) for real-time classification. The combination of the two methods produced better class separation, improving separation ratio by up to 4 times compared to single modality. The dual-mode DNN achieved 98.2% confidence in predictions, 8% higher than either mode alone. Integrating surface and subsurface data provide real-time determination of crystallinity in thermoplastic polymers.
