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

open access: yesChemistry – 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

Valorization of Juice Industry Waste Into Foam‐Like Materials Using Mycelium as Natural Binder

open access: yesCleanMat, EarlyView.
This study explores converting carrot pomace, a juice industry byproduct, into eco‐friendly mycelium‐based foams using Aspergillus oryzae. The foams, produced via submerged cultivation, grinding and freeze‐drying, showed promising mechanical properties comparable to commercial foams, offering a sustainable alternative to synthetics while promoting ...

Stimuli‐Responsive 3D‐Printed Structurally Colored Materials Based on Core–Shell Particle Architectures

open access: yesMacromolecular Materials and Engineering, EarlyView.
A novel, structurally colored and pH‐responsive filament for FDM 3D‐printing is presented, which is based on tailored core–shell particles with methacrylic acid as a comonomer in the particle shell. The pH‐responsiveness of the printed objects is achieved due to particle swelling in alkaline conditions.

3D Polymeric Nanonetworks: From Self‐Assembly to Advanced Fabrication

open access: yesMacromolecular Materials and Engineering, EarlyView.
This review provides the first systematic cross‐method comparison of fabrication techniques for 3D polymeric nanonetworks. It evaluates five key strategies—block copolymer self‐assembly, hyper‐crosslinking, template‐assisted methods, 3D printing, and nanolithography—across critical metrics including resolution, throughput, scalability, and material ...

Mono‐ and Bivalent Poly(iso‐butylene)‐Alanines for Drug‐Delivery of Nimodipine and Triamcinolone Acetonide

open access: yesMacromolecular Rapid Communications, EarlyView.
Mono‐ and bivalent‐, alanine‐modified poly‐iso‐butylenes, folding into beta‐sheets, were prepared by living carbocationic polymerization and subsequent endgroup modification. These PIB‐conjugates are useful as solid polymers for the drug release of triamcinolone and nimodipine. ABSTRACT Poly‐iso‐butylene (PIB) is a well known biocompatible polymer with

Poly(L‐Lactide‐Co‐ε‐Caprolactone)/glass Fiber Composites: Toward Improved Mechanical Properties of Polylactide‐Based Composites

open access: yesPolymer Composites, EarlyView.
Enhanced impact strength in PLLA‐based composites via ε‐caprolactone incorporation in the matrix. ABSTRACT Inherent brittleness and limited toughness of polylactide (PLA) restrict its use in high‐performance applications. To overcome these limitations, poly(L‐lactide) (PLLA) is often blended with more ductile thermoplastics or chemically modified ...
