Anomalous Toughening of Glassy Ionic Comb Polymers: Retention of Homogeneity Achieved by Bulky 4-Dimethylaminopyridinium Counterions
Overcoming the trade-off between stiffness and toughness is a longstanding challenge for glassy polymers. While ionic toughening with a homogeneous nanostructure offers a potential solution, this behavior remains limited to specific ionic liquid-based systems. Here, we show that incorporating 4-dimethylaminopyridine...
