Numerous nacre-inspired composite materials has been introduced with exceptional mechanical properties in structural materials. However, few study on electrical composite materials is reported. Here, we introduced 'Nacre-inspired stretchable thin film electrodes' by exploiting the use of polydimethylsiloxane (PDMS) as substrate, and inevitable low-molecular weight (LMW) PDMS on the surface. The diffused LMW PDMS in the metal grains and layers will act as a viscoelastic glue similar to the ‘protein organic layer’ in the ‘brick-and-mortar’ structure of natural Nacre, allowing the brittle metal platelets to frictionally slide when the structure is stretched. Furthermore, the ultrathin thickness together with the sparse structure of the molecular layer can provide an electrical path between the interlayers of the metal films via an electron tunnelling effect. Thereby,the materials shall maintain a high conductivity under mechanical deformation, enabling the production of stretchable electrodes.
