On the growing demands for E-skin (electronic-skin), interest in stretchable conducting materials for wiring is also increasing. From structural design to composite material design, stretchable conducting composite materials have been studied in various approaches. In this research, we have optimized condition for highly stretchability and electrical stability by using poly(Styrene-Isoprene-Styrene) triblock copolymer (SIS) and poly(Styrene-Butadiene-Styrene) triblock copolymer (SBS). Also, we demonstrated conducting thin films with Ag flakes, which is stable after few hundreds cycling test. This performance comes from the appropriate trade-off point between silver rich and silver poor condition. The ratio of silver to polymer plays significant role in optimizing the property between high percolated but brittle and low percolated but viscous. |
