WebPBS crystallization was inhibited in the blends with higher contents of PBAT, and FTIR and SEM analysis suggested that limited interactions occur between the two polymer phases. The films showed increasing stiffness as the PBS percentage increased; further, a sharp decrease in elongation at break was noticed for the films containing percentages ... WebFeb 20, 2024 · The IR spectra of the PLA/PBAT composite samples were recorded with a Bruker Lumos FTIR spectrometer and microscope macromodule in the 4000–600 cm −1 range. The samples were analyzed with a Vega 3 scanning electron microscope (Tescan, Czech Republic).

WebMar 12, 2024 · FTIR and XRD data showed that the addition of 1, 3 and 5% of starch had no significant effect on the PLA/PBAT matrix, because there was no formation of new bonds and nor a new transcrystalline phase was identified at the interface of the mixtures induced by the incorporation of CS or BMS. WebMay 19, 2024 · Aromatic ring in PBAT acts as a sink and delocalized radicals created by UV ray so less chain scission is resulted. The degradation might be due to ester chain scission and crosslinking which made the polymer brittle and led to weight loss. 3.4 FTIR spectrum of nanoparticles.
