a Accelerated healing mechanism of IMG microdrops with a net charge induced by electrons and moisture. b Photographs of the crack healing process using EAP strategy taken with microscopy. Scale bar, 20 μm. In situ FT-IR spectroscopy using (c) conventional drip-coating method with a time interval of 20 min and (d) EAP strategy through continuous testing. e Corresponding changes in the degree of polymerization over time, where the EAP strategy speeds up by 21.4 times. f In situ Raman of the EAP healing process in a drying room with a dew point temperature of less than − 35 °C. SEM cross-section views of SSNMB using (g) CLE and (h) EAP strategy at the interface. Scale bars, 50 μm.
