Lichen‐Derived Mineral Residue as a Renewable Particulate Filler in Polylactic Acid Biocomposites: Structure, Melt Rheology, Viscoelastic, and Flexural Behavior
A lichen‐derived natural material, known as “höllük” in southeastern Turkey, is introduced as a renewable filler for polylactic acid (PLA). X‐ray diffraction and scanning electron microscope analysis of höllük identified quartz and calcite as the major crystalline phases within a silicate‐organic matrix, and thermo...
