Characterization and analyzation of the poly (L-lactic acid) (PLA) films

In this study aims to characterized and analyzed the poly (L-lactic acid) (PLA) films as the biodegradable film. The solvent casting techniques is used to prepare the PLA film. The Physical properties of film such as, structural, morphology, thickness were studied and discussed with X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM), respectively. For chemical properties, the chemical compositions and the formation of functional group were investigated by Energy Dispersive X-Ray Fluorescence (EDXRF) and Fourier Transform Infrared (FTIR), respectively. The results of XRD showed that the PLA film composed of amorphous phase. While, the result of EDXRF shown the trace elemental composition of the PLA film composed of organic compound (CHO), Ca, P, and Ag respectively. The photograph of SEM found that the surface of PLA film look like surface of the moon which has the crater spread over the film and the thickness of the PLA films about 0.600 mu m. So that, the spectrum of FTIR can be concluded that the number of functional groups compose of methyl groups, carbonyl group and hydroxyl group, respectively. (C) 2018 Elsevier Ltd.
