Separation of Polyamide 66 From Blends With Wool Through Selective Dissolution: Implications of the Presence of Dyes

open access: yesJournal of Applied Polymer Science, EarlyView.
The study assesses dye impacts on PA66/wool recycling via selective PA66 dissolution in calcium chloride–ethanol–water and water reprecipitation. Acid dyes migrate into solvent, yielding color‐free, melt‐spinnable PA66 and reusable wool. Metal‐complex dyes remain, altering PA66 melt viscosity and requiring extraction or repurposing.

From brush conformation to 3D Supraparticles: Programmable self‐assembly of polymer‐grafted nanoparticles in emulsion confinement

open access: yesBulletin of the Korean Chemical Society, EarlyView.
This review highlights how the conformational adaptability of polymer‐grafted nanoparticles drives their programmable self‐assembly within 3D emulsion droplets. By coupling brush thermodynamics with soft confinement, these dynamic building blocks form hierarchical supraparticles tailored for advanced plasmonics, compartmentalized catalysis, and stimuli‐

National Environmental Policies and Corporate Green Innovation: The Mirroring Versus Substitution Hypotheses

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Drawing on comparative institutional theory, we study the nature and magnitude of the effects of national environmental policies on corporate green innovation in developed versus emerging markets. Using a sample of 1831 listed firms in 34 countries from 2002 to 2020, we find that national environmental policies increase corporate green ...
