Effect of thermomechanical pulp fibers and clay on the characteristics of high‐ and low‐density polyethylene biocomposites

open access: yesPolymer Composites, EarlyView.
Thermomechanical pulp fibers and clay compounded with high‐ and low‐density polyethylene biocomposites for injection moulding. Abstract This study focused on the performance evaluation of clay and thermomechanical pulp (TMP) fiber to reinforce low‐ and high‐density polyethylene (LDPE and HDPE) biocomposites. A 23 factorial experiment was designed using

Imino‐Pyrrole Zn(II) Complexes for the Rapid and Selective Chemical Recycling of Commodity Polymers

open access: yesAngewandte Chemie, Volume 137, Issue 22, May 26, 2025.
Three imino‐pyrrole zinc (II) catalysts were prepared and applied to the chemical recycling of PLA, PET, and BPA‐PC. Rapid PLA degradation was accomplished in solution and under solvent‐free conditions, the latter giving full conversion at relatively mild temperatures after 11 min.

Development of graphite‐reinforced PLA/PBAT composite filaments

open access: yesPolymer Composites, EarlyView.
Production scheme of biodegradable graphite‐based filaments for 3D printing. Abstract Additive manufacturing, particularly Fused Deposition Modeling (FDM), has been increasingly used due to its ability to create complex and personalized products. Besides, this processing technique can be performed with biodegradable polymers such as polylactic acid ...

Uniaxial Stretching of Biodegradable Poly(Butylene Succinate‐Co‐Adipate) Films Filled With Silane‐Treated Wollastonite: Processing and Performance Evaluation

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 28, July 20, 2025.
Biobased poly(butylene succinate‐co‐adipate) films filled with silane‐treated wollastonite were engineered using blown film extrusion followed by uniaxial stretching. The tensile strength and moisture barrier properties of 15% filled films improved by approximately 213% and 12%, respectively, after uniaxial stretching.
