Bio-inspired hydrogel can rapidly switch to rigid plastic

The gel is soft and transparent at 25°C and cannot support a 10 kg weight (top panels) but it quickly becomes rigid and opaque when heated to 60°C, becoming strong enough to support the weight (bottom panels). (Source: Nonoyama T. et al., Advanced Materials, November 18, 2019)
