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 ...

Biodegradable starch-based films containing saturated fatty acids: thermal, infrared and raman spectroscopic characterization

Polímeros, 2012
Biodegradable films of thermoplastic starch and poly (butylene adipate co-terephthalate) (PBAT) containing fatty acids were characterized thermally and with infrared and Raman spectroscopies. The symmetrical character of the benzene ring in PBAT provided

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

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

Directed Evolution of an Efficient Polycarbonate Depolymerase With Exceptional Operational Stability

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Here, we show that well studied PET hydrolases can be re‐engineered via directed evolution to deconstruct alternative aromatic‐containing commodity polymers. Introduction of only three mutations into LCCICCG was sufficient to generate an efficient polycarbonate hydrolase with high operational stability that can fully depolymerize a polycarbonate sample

Interactions, structure and properties in poly(lactic acid)/thermoplastic polymer blends [PDF]

, 2014
Blends were prepared from poly(lactic acid) (PLA) and three thermoplastics, polystyrene (PS), polycarbonate (PC) and poly(methyl methacrylate) (PMMA). Rheological and mechanical properties, structure and component interactions were determined by various ...
