Stretchable Full-Color Phosphorescent PVA-Based Ionogels for Multimodal Sensing-Visual Integration Applications.

ABSTRACT: Exploring ionogels with superior conductivity, mechanical properties, and long-lasting room temperature phosphorescence (RTP) offers considerable potential for new-generation optoelectronics. However, reports on ionogels remain limited owing to the contradiction between the flexibility required for stretching and the rigidity necessary for RTP and load-bearing within the same ionogels. Here, a facile strategy is reported to enhance the toughness and extend the RTP of ionogels by salting-out-induced microphase separation, which results in the formation of an IL-rich phase (soft) for stretching and ionic conduction and a polymer-rich phase (stiff) for energy dissipation and clustering-triggered phosphorescence. The obtained ionogels exhibit high stretchability (≈400% strain), toughness (≈∼20
