Lichen‐Derived Mineral Residue as a Renewable Particulate Filler in Polylactic Acid Biocomposites: Structure, Melt Rheology, Viscoelastic, and Flexural Behavior

open access: yesPolymer Composites, EarlyView.
Lichen residue, a renewable mineral‐organic material, was melt compounded with polylactic acid and triacetin in a twin‐screw extruder. ABSTRACT A lichen‐derived natural material, known as “höllük” in southeastern Turkey, is introduced as a renewable filler for polylactic acid (PLA).

Nanocellulose Hybrid Reinforcement in Surface‐Modified Pistachio Shell/Epoxy Composites: A Multiscale Interface Engineering Strategy for Lignocellulosic Biomass‐Based Materials

open access: yesPolymer Composites, EarlyView.
Sustainable high‐performance epoxy composites reinforced with functionalized pistachio shell waste and nanocellulose. ABSTRACT In this study, pistachio shell waste (PShW) was used as a lignocellulosic reinforcing phase in an epoxy matrix to develop sustainable composite materials, and its surface properties were tailored using various chemical ...

Interplay Between Dispersion, Nucleation, and Crystallization in HDPE/Graphene Nanocomposites Processed Under Thermokinetic Conditions

open access: yesPolymer Engineering &Science, EarlyView.
Thermokinetic processing controls graphene fragmentation and dispersion in HDPE, promoting heterogeneous nucleation and multistep crystallization. The balance between nucleation enhancement and chain mobility restriction governs the final crystalline structure and material performance.

Robust β‐myrcene block copolymer elastomeric vitrimers

open access: yesPolymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Viscoelastic Modeling of Stress Relaxation in Model High‐Performance Covalent Adaptable Networks

open access: yesJournal of Polymer Science, EarlyView.
Covalent adaptable networks, often referred to as vitrimers, contain a certain fraction of bonds that are able to exchange with other bonds. The ability of this bond exchange to relax stress or result in flow of the material depends on the concentration and specific concentration of these bonds in ways that can be quantified.
