Serious environmental pollution and human health issues can arise due to the enhanced utilization of synthetic plastics manufactured from petroleum resources. Therefore, biodegradable polymers (bio-plastics) made from renewable biological materials like natural aliphatic polyesters poly (lactide) (PLA), poly (butylene adipate-co- terephthalate) (PBAT), etc., are considered as eco-friendly plastics that last for a limited period of time in the environment.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
In this paper, Ko et al. have studied the biodegradation of a hydrophilic ternary blend of PBAT-PLA with TPS (thermoplastic starch) by the act of fungal strains at ambient conditions. The surface morphology of the commercial bio-plastic films of PBAT-PLA-TPS was observed by scanning electron microscopy (SEM). The samples were prepared for the SEM analyses by mounting the films on a carbon tape and\u00a0coating<\/strong>\u00a0them with a 20 nm thickness platinum film using Vac Coat DSR1<\/a> ion sputter coater.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n The optical and SEM images of the films with or without the fungal strains at different time intervals are shown below.<\/p>\n<\/div>\n<\/div>\n
