Investigation of the Mechanical Behaviors of Waterborne Polyurethane: The Critical Influence of Hard Segment Content Over Various Strain Rates

open access: yesMacromolecular Materials and Engineering, EarlyView.
This study explores how hard segment content (HS) modulates waterborne polyureathane's (WPU's) dynamic mechanical properties under low/high strain rates. Increasing HS enhances hydrogen bonding and microphase separation, with abundant hard domains acting as physical crosslinks.

Lipoic Acid Based Redox‐Responsive Degradable Antimicrobial Polymers

open access: yesMacromolecular Rapid Communications, EarlyView.
Antimicrobial polymers are emerging as a vital tool against drug‐resistant pathogens. This article introduces a new class of degradable, disulfide‐containing polymers synthesized through reversible addition‐fragmentation chain transfer (RAFT) polymerization. These innovative materials, featuring benzyl lipoate, effectively combat Pseudomonas aeruginosa

From Formica® to FormiCAN: One‐Pot Synthesis of Melamine‐based Covalent Adaptable Network Endowed With High Transition Temperature and Fast Stress Relaxation

open access: yesMacromolecular Rapid Communications, EarlyView.
Melamine‐based resins are benchmark materials in the field of laminates and composites, and this beyond the world‐famous Formica® brand, but these thermosets are not reprocessable and hardly degradable. This study describes a melamine‐based CAN containing N,O‐acetal exchangeable functions, obtained via a one‐pot and solvent‐free microwave‐assisted ...
