Study Background:

The research presented titled “Synthesis and detailed characterization of sustainable starch-based bioplastic” by Ishita Chakraborty | Pooja N. | Soumyabrata Banik | Indira Govindaraju | Kuheli Das | Sib Sankar Mal | Guan-Yu Zhuo | Muzamil Ahmad Rather | Manabendra Mandal | Ashamoni Neog | Rajib Biswas | Vishwanath Managuli | Amitabha Datta | Krishna Kishore Mahato | Nirmal Mazumder is investigated the structural and functional characteristics of bioplastic. Development and detailed characterization of the biodegradable bioplastics from plant-based polysaccharides such as starch is essential to reduce plastic pollution in the environment. In this research, bioplastics were developed from an equivalent blend of starch from two different sources namely rice and potato (1:1, w/w), crosslinked with different concentrations of citric acid (CA). The effect of CA cross-linking of starch-based bioplastics was investigated on its physicochemical and functional properties. The X-ray diffraction (XRD) spectra revealed that the synthesized bioplastics were amorphous in nature with broad diffraction peaks. Further, the peak at 1716 cm1 in Fourier transform infrared (FTIR) spectra indicated the formation of ester bonds in CA cross-linked bioplastics. Atomic force microscopy (AFM) revealed the surface roughness of the bioplastics decreased with increasing concentration of CA. Mechanical and thermal properties of bioplastics were characterized using universal testing machine, differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA), respectively.
