- Abstract
This study aims to evaluate the effects of poly(2-ethyl-oxazoline) (PEOx) on the thermal properties, wettability, and optical properties of poly(lactic acid) (PLA). The PLA/PEOx blends (PEOx loading: 5 to 20 wt%) were prepared using the solvent casting method. Good interaction between PLA and PEOx was confirmed by Fourier transform infrared spectroscopy (FTIR) and work of adhesion (determined from dynamic contact angle). The transparency of PLA was improved by the addition of PEOx. X-ray diffraction (XRD) and differential scanning calorimetry (DSC) results proved that the PEOx induces the β-crystals formation of PLA. The higher the loading of PEOx is, the higher the intensity of the β-crystals formation. The transparent PLA/PEOx blends are suitable for packaging applications (both non-food and food packaging).
