Seawater‐Degradable Polymers—Fighting the Marine Plastic Pollution [PDF]

, 2020
Polymers shape human life but they also have been identified as pollutants in the oceans due to their long lifetime and low degradability. Recently, various researchers have studied the impact of (micro)plastics on marine life, biodiversity, and ...

Magnetic Textiles: A Review of Materials, Fabrication, Properties, and Applications

Advanced Materials Technologies, EarlyView.
Magnetic textiles (M‐textiles) are emerging as a programmable materials platform that merges magnetic matter with hierarchical textile structures. This article consolidates magnetic material classes, textile architectures, and fabrication and magnetization strategies, revealing structure–property–function relationships that govern magneto‐mechanical ...

Natural Antioxidants as Thermal Stabilizers in Post‐Consumer Polypropylene

Journal of Applied Polymer Science, EarlyView.
A synergistic antioxidant system combining two natural antioxidants, quercetin and tocopherol, enhances the thermo‐oxidative stability of recycled polypropylene. The approach addresses key barriers to the utilization of recycled polymers, offering a sustainable pathway to improve material performance and supporting the broader adoption of recycled ...

Better Material Properties and Faster Catalyzed Chemical Recycling for Poly(L‐Lactide) Using a Simple Commercial Glycerol Ethoxylate Additive

Chemistry – A European Journal, EarlyView.
Glycerol ethoxylate (GEO), a branched ethylene glycol derivative, both toughens commercial PLLA and accelerates its chemical recycling to L‐lactide. The lead sample, containing 10 wt.% GEO, shows 9x higher elongation at break and 6x higher tensile toughness than pure PLLA. The GEO–PLLA samples are efficiently chemically recycled to L‐lactide, even when
