Janire Aramberri, Matías L. Picchio, Aitor Barquero
TL;DR
This paper introduces menthol-based eutectic solvents as eco-friendly plasticizers for biobased acrylic polymers, offering a sustainable alternative to toxic VOCs.
Contribution
The novelty lies in using menthol-based hydrophobic eutectic solvents as green, multifunctional plasticizers for biobased acrylic films.
Findings
The plasticizer effect in biobased polymers can be controlled by the polarity and vapor pressure of eutectic components.
Menthol-based HESs show potential for use in therapeutic patches due to their bioactive properties.
The films were characterized for chemical structure, thermal, adhesive, and mechanical properties.
Abstract
While the polymer industry has gained importance in the last decades, many related environmental issues have appeared, caused by oil-based monomers, unsustainable polymerization processes, and toxic additives, among others. For instance, plasticizers commonly used in acrylic polymers often qualify as volatile organic compounds (VOCs), raising concerns due to their contribution to indoor air pollution, regulatory restrictions, and potential health risks. In this work, we explore a series of menthol-based hydrophobic eutectic solvents (HESs) as green alternatives to conventional organic plasticizers for acrylic films based on biobased isobornyl methacrylate (IBOMA), 2-octyl methacrylate (2-OMA), and their copolymers synthesized via miniemulsion polymerization. The biobased films were thoroughly characterized to assess their chemical structure, thermal, adhesive, and mechanical properties…
