Three different types of starch-based bioplastic blends were synthesized and characterized using FTIR spectra, XRD spectra, and biodegradability test. The results demonstrated the plastic nature of the samples and their significant volume degradability.
Three different types of starch based bioplastic blends were synthesized. The FTIR spectra, XRD spectra and biodegradability test were used to characterize them. The FTIR spectra have shown the bands attributed to the stretching vibrations of hydroxyl groups (O-H) and carbonyl groups -CH, -CH2, C=O, C=C, C-O-C etc. The FTIR spectra confirmed the plastic nature of the samples by tracing the different functional groups of regular plastics. The XRD spectra have depicted the short range periodicity of the samples. Two samples have exhibited feeble diffraction peaks at 15.5 degrees, 18.2 degrees, 21.5 degrees and 23.2 degrees. The decomposition test found that these samples have appreciable percentage of volume degradability in the soil. (C) 2021 Elsevier Ltd. All rights reserved.
