N2 - In this study, we fabricated a stretchable freestanding ultrathin sheet based on a polystyrene-polybutadiene-polystyrene (SBS) copolymer with entropy-driven elasticity and evaluated its optomechanical properties. The freestanding SBS sheet had a thickness of 675nm and a size of 10.4 ' 10.4mm2 on a through hole of a poly(dimethylsiloxane) (PDMS) sheet. The measurement of the reflection spectra of the optical interference peaks of the stretched sheets revealed that the SBS nanosheet had a Poisson's ratio of 0.5-0.68 for a 38% elastic strain, which is one order of magnitude greater than that of parylene.
