Biodegradable Biocomposites of Isosorbide‐Plasticized Corn Starch Reinforced With Green Graphene: Enhanced Properties for Sustainable Applications

Polymer Composites, EarlyView.
Different properties of biocomposites based on TPS with isosorbide as a plasticizer and green graphene filler. ABSTRACT New biocomposites of corn starch plasticized with isosorbide and filled with two types of “green” graphene with different oxygen content, 1% (G99) and 8% (G92), were processed by melt blending.
