Effect of Polypropylene‐Grafted‐Maleic Anhydride and Rice Husk Particle Size on 3D‐Printing Filament Composites From Recycled Polypropylene

Polymer Composites, EarlyView.
Development of 3D printing composite filaments from recycled polypropylene and agro‐industrial residues: blending, extrusion, and mechanical validation. ABSTRACT This study evaluates the combined roles of particle size and the addition of maleic anhydride polypropylene (PP‐g‐MAH) to improve 3D printing and mechanical properties of composite filaments ...

Structural and Dynamic Origins of Payne Effect Reduction by Steric Stabilization in Silica Reinforced Poly(butadiene) Nanocomposites

Polymer Composites, EarlyView.
Steric stabilisation of silica nanoparticles suppresses the Payne effect in poly(butadiene) nanocomposites and enables the thickness of the glassy layer to be quantified with QENS experiments. ABSTRACT Silica nanoparticles in polybutadiene nanocomposites cause significantly hindered polymer dynamics in the form of a glassy layer, which can extend more ...

Solution‐Like Water Transport Across Molecular to Macroscopic Length Scales in Crosslinked Poly(Ethylene Glycol Diacrylate) Networks With Tailored Sidechains

Journal of Polymer Science, EarlyView.
Cross‐linked PEGDA network microparticles are synthesized with spin labels to sense local water motion. From the nanoscale to the macroscale, PEGDA exhibits rapid, solution‐like water transport as measured by spectroscopic techniques. Addition of side chain chemistries further modulates local water diffusion.

A consistent coupling of two‐moment microphysics and bulk ice optical properties, and its impact on radiation in a regional weather model

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study presents a novel, consistent coupling of two‐moment microphysics (i.e., ice mass mixing ratio and number) with bulk ice optical properties, providing improved accuracy in radiative transfer simulations. The parametrisations, based on the mass‐equivalent spherical radius, avoid uncertainties associated with the effective radius by directly ...
