New Strategy for Upcycling Marine Plastic Waste Through the Development of a Diamine-Functionalized Poly(ethylene terephthalate) Compatibilizer

Recycling
A compatibilizer for low-density polyethylene (LDPE)/poly(ethylene terephthalate) (PET) blends was developed. This compatibilizer consists of amine-functionalized PET, which is blended with maleated polyethylene to form a copolymer.

Enhanced Biocatalysis in Nanofluidic Membrane Reactors With Goldilocks Nanopores for Enzymes

Small, EarlyView.
We show that enzyme confinement within the three‐dimensionally interconnected nanochannels of a polyurea molecular network membrane, featuring pore‐size tunability to match the enzyme size, enables a highly active nanofluidic reactor platform. Stable continuous‐flow operation for >200 h and a 30 000‐fold increase in specific space‐time yield over ...

Thermal Degradation Kinetics and Flame‐Retardant Synergy in Zinc Borate/Red Phosphorus‐Filled Thermoplastic Polyurethane Composites

Journal of Vinyl and Additive Technology, EarlyView.
The synergistic interaction between red phosphorus (RP) and zinc borate (ZnB) enhances the thermal stability and flame retardancy of TPU by forming a dense, stable protective char layer. Non‐isothermal kinetic analysis confirms a complex degradation mechanism governed by conversion‐dependent activation energy.

High Density Polyethylene/Ground Tire Rubber Composites Compatibilized by Dicumyl Peroxide

Journal of Applied Polymer Science, Volume 143, Issue 25, July 5, 2026.
ABSTRACT In this study, the thermal behavior of dicumyl peroxide (DCP) was first evaluated by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), which confirmed a peak decomposition temperature around 172°C, highlighting its incompatibility with standard melt‐mixing techniques for most polyolefins. To overcome this limitation,
