Abstract Transparent and conductive silver nanowires (AgNWs)-filled methylcellulose (MC) composite films were fabricated by blending silver nanowires (AgNW) with a methylcellulose solution. AgNW concentration showed significant influence on the optical, electrical and mechanical properties of composite films. The percolation threshold of AgNWs-filled methylcellulose composite films in this study was approximately 0.29 vol%. A three-dimensional (3D) network-like composite film with micron-scale thickness demonstrated the electrical percolation of the two-dimensional (2D) network. Methylcellulose blended with silver nanowires showed enhanced mechanical properties such as tensile strength and Young׳s modulus compared with pure methylcellulose matrix.
