Large-area preparation of flexible carbon nanofilms with synergistically enhanced transmittance and conductivity

Large-area flexible transparent conductive films (TCFs) are urgently needed for future electronics, optoelectronics, energy devices and other fields. Indium tin oxide (ITO) TCF, which is widely used in modern technology, faces difficulties in meeting the needs of scientific and technological development (especially a new generation of flexible electronic devices) because indium is a non-renewable resource and expensive, and ITO is inherently brittle.
