Transparent and flexible cellulose nanofibers/silver nanowires/acrylic resin composite electrode Part A Applied science and manufacturing

In this study, we report a novel, eco-friendly and simple method to fabricate cellulose nanofibers (CNFs)/silver nanowires (AgNWs)/acrylic resin (AR) composite electrode. CNFs with average diameter of 15nm were disintegrated only by one time-pass grinding. Aqueous dispersion of AgNWs was embedded onto the surface of CNFs film by simple vacuum filtration. The final composite electrode was obtained by impregnating CNFs/AgNWs film to AR with the assist of adhesive tape. This electrode with AgNWs density of 134mg/m² showed low sheet resistance (4Ω/sq), and high light transmittance (85%) which was 6% lower than that of neat AR. The coefficient of thermal expansion of the composite electrode was as low as 25.32ppmK⁻¹. The tensile strength and Young’s modulus of CNFs/AgNWs/AR composite film were 35.71MPa and 1.63GPa, which were about 8 and 5.8times larger than neat AR film, respectively.
