Convergence of Organ‐on‐a‐Chip and Freeform Printing of Sacrificial Poly(2‐cyclopropyl‐2‐oxazoline) Enables the Generation of Perfusable Endothelialized Channels in Hydrogels

open access: yesMacromolecular Rapid Communications, EarlyView.
We employ freeform printing of thermo‐responsive poly(2‐oxazoline) to directly fabricate suspended sacrificial vascular templates within Organ‐on‐a‐chip devices. This enables circular, perfusable channels down to 200 µm without post‐processing.

Metathesis‐Sourced Epoxides in Ring‐Opening Copolymerization: Selective Access to Degradable Polythioesters

open access: yesMacromolecular Rapid Communications, EarlyView.
Metathesis‐derived cyclopentene epoxides enable strictly alternating, scrambling‐free ring‐opening copolymerization with phthalic thioanhydride, yielding well‐defined polythioesters with molecular weights up to ∼38 kg/mol. Their performance extends to oxygen‐based anhydrides and selective terpolymerizations. Direct comparisons with all‐oxygen analogues

Microstructure–Mechanical Response Relationship in Discontinuous Fiber‐Reinforced SMC Composites: Damage Mechanisms

open access: yesPolymer Composites, EarlyView.
Architecture of SMC composites. ABSTRACT The mechanical performance of sheet molding compounds (SMCs) is dependent on microstructural characteristics determined by material composition and processing conditions. The study investigates standard SMCs, advanced SMCs (A‐SMCs), and low‐density SMCs (LD‐SMCs) under quasi‐static and fatigue loading to ...

The Role of Cold Atmospheric Plasma in Surface Modification and Adhesion Behavior of Polypropylene/Flax Biocomposites

open access: yesPolymer Composites, EarlyView.
Effects of plasma surface treatment on adhesive bonding of PP/flax biocomposites. ABSTRACT The emphasis on environmental sustainability has accelerated the adoption of biocomposites as alternatives to synthetic composites. However, their low surface energy may limit adhesion in bonding applications.

Masterbatch‐Assisted Fabrication of Polylactic Acid/Reduced Graphene Oxide Nanocomposites Exhibiting Mechanical Enhancement and UV‐C Aging Resistance

open access: yesPolymer Composites, EarlyView.
Masterbatch‐Assisted Fabrication of Polylactic Acid/Reduced Graphene Oxide Nanocomposites. ABSTRACT Polylactic acid (PLA) is a promising bio‐based polymer; nonetheless, its extensive application is still limited by poor fracture toughness, low thermal stability, and strong susceptibility to degradation induced by ultraviolet (UV) radiation.

Melt Electrospinning of Poly (ε‐Caprolactone)/Polyethylene Oxide/Polyethylene Glycol—Hydroxyapatite Nanocomposite Fibers: Morphology, Properties, and Hydrolytic Degradation

open access: yesPolymer Engineering &Science, EarlyView.
The fabrication of nanocomposite fibers based on a ternary PCL/PEO/PEG blend reinforced with hydroxyapatite nanoparticles via melt electrospinning resulted in improved nanoparticle uniformity, fine‐tuning of the microstructure and mechanical properties, and accelerated hydrolytic degradation; features that make this system a promising platform for bone
