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

open access: yesPolymer Composites, Volume 47, Issue 7, Page 6744-6759, 10 April 2026.
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.

Enhancing Polylactic Acid Films With Polyethylene Glycol‐Based Plasticizers: A Reactive Extrusion Approach

open access: yesMacromolecular Rapid Communications, Volume 46, Issue 14, July 18, 2025.
This study explores the enhancement of polylactic acid (PLA) films through reactive extrusion with polyethylene glycol (PEG)‐based plasticizers and dicumyl peroxide (DCP) as a cross‐linking agent. The process improves mechanical strength, ductility, and thermal stability while reducing plasticizer migration, broadening the potential applications of PLA
