Crystallization behavior and intermolecular hydrogen-bonding interactions of poly(3-hydroxybutyrate) (PHB)/chitin blends on as-solution cast films were studied as a function of composition and temperature by differential scanning calorimetry (DSC), wide-angle X-ray diffraction (WAXD) and infrared (IR) spectroscopy. The significant changes were observed in the DSC curves, WAXD patterns and IR spectra...
Time-dependent infrared (IR) spectra were measured for isothermal melt-crystallization process of poly(l-lactide) (PLLA), poly(l-lactide)/poly(d-lactide) (PLLA/PDLA) stereocomplex, and poly(3-hydroxybutyrate) (PHB), and the spectra were analyzed for the C–H and CO stretching band regions to explore the CH 3 ⋯OC interactions in the above polymers. Both PLA and PHB are well known biodegradable...
