Stretchable ionogels have recently emerged as promising soft and safe ionic conductive materials for use in wearable and stretchable electrochem. devices. However, the complex preparation process and insufficient thermomech. stability greatly limit the precise rapid fabrication and application of stretchable ionogels. Here, we report an in situ 3D printing method for fabricating high-performance single network chem. ionogels as advanced strain sensors. The ionogels consist of a special crosslinking network constructed by poly(ionic liquid) and hyperbranched polymer (macro-crosslinkers) that exhibits high stretchability (>1000%), superior room-temperature ionic conductivity (up to 5.8 mS/cm), and excellent thermomech. stability (-75 to 250°C). The strain sensors based on ionogels have a low response time (200 ms), high sensitivity with temperature independence, long-term durability (2000 cycles), and excellent temperature tolerance (-60 to 250°C) and can be used as human motion sensors. This work provides a new strategy to design highly stretchable and superior stable electronic devices. In the experiment, the researchers used 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6Reference of 3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate)
3-Butyl-1-methyl-1H-imidazol-3-ium tetrafluoroborate(cas: 174501-65-6) is a member of lonic liquids. Actually, lonic liquids as innovative fluids have received wide attention only during the past two decades. The number of SCI papers published on lonic liquids has exponentially increased from a few in 1996 to >5000 in 2016, exceeding the annual growth rates of other popular scientific areas.
