V2O5 nanowires (NWs) are attracting much attention in various applications such as FET, anti-static films, sensors and actuators because of their outstanding material properties of easy synthesis, homogeneity, and semiconducting behavior. However, general strategy of a NW-related fabrication has been limited to utilize and control the individual NWs to realize nano-electronic devices. In order to extend the applicability of V2O5 NWs to the conventional electronic devices, therefore, we fabricated 3D structures of V2O5 NWs through the multilayer transfer printing of V2O5 hybridized polyelectrolyte multilayers. First, we prepared alternatively deposited films of polycation and polyanion mixed with charged V2O5 NWs onto the patterned PDMS substrate. Then, the top patterns of PDMS mold finished with negatively charged polymer was transferred to a positively charged surface using electrostatic attractions. Finally, 3D structures of V2O5 NWs can be fabricated via consecutively transferring the hybridized films, which will be beneficial for the development of flexible electrodes. |
