Pooi See?Lee (Nanyang Technological Univ., Singapore)
Abstract: ? Deformation displays such as electroluminescent devices or electrochromics devices require the use of stretchable and deformable transparent conducting substrates for the electrodes formation. The conducting electrodes in displays ideally possess the characteristics of superior conductivity and optical transparency under extreme conditions such as folding, stretching, flexing, rolling or crumpling. We report our strategies on the preparation and fabrication of flexible, stretchable transparent conductors for electrochromics and electroluminescent devices. We have developed an effective?transfer method to prepare transparent conductors with high figure of merit. It improves the interface properties and bonding stability between the conductive constituents and the matrix. The method can be used to transfer various nanostructures. The resultant composite consisting of cellulose nanofibrils with metallic nanowires is used to fabricate flexible and foldable transparent conductors for the preparation of flexible wearable electrochromics. Improved interaction with the overlay electrochemical active material was observed, it enhances charge intercalation and facilitates ionic diffusion in the presence of electrolyte due to the hydrophilic?surfaces, making this an ideal substrate for chromogenic display.
