 highlights a flexible freestanding TAS2 film, thickness equals 3.1 micrometers, exhibits an ultra-lovoid ratio of 6.01%, an ultra-high electrical conductivity of 2,666 SCM-1, and electromagnetic interference shilling effectiveness, EMI say, of 41.8 dB, an absolute EMI say, SSS slash T, of 27,859 dB CM2G minus 1, and excellent flexibility with STAN-1000 bends without rupture. The TAS2 composite films exhibit excellent EMI shielding properties and higher tensile strength with better mechanical flexibility, making them suitable for EMI shielding practical applications.
