Abstract
Silver nanowires are a promising nanomaterial for the fabrication of transparent flexible conductive films Due to their fascinating properties numerous studies have been done to determine the relationship among nanowire properties micronetwork structure and optoelectronic properties such as transparency and conductivity12 However most previous studies have used methods that are not suitable for mass production such as vacuum filtration To produce the film economically it is advisable to use a solution process eg a liquid coating method In this study we use a simple dip coating method to produce the film using a coating solution which disperses nanowires in isopropyl alcohol The amount of nanowires on the film is carefully controlled by the wet film thickness predicted from computational analysis The important parameters of nanowire networks such as the diameter the aspect ratio and the areal coverage of nanowires are measured directly from image analysis of the electron microscopy images Finally the relationship among those parameters and optoelectronic properties is examined in detailThis research was supported by the Basic Science Research Program through the National Research Foundation of Korea NRF funded by the Ministry of Science ICT Future Planning Grant No NRF2013R1A1A1004986 This work was supported by the Korea Sanhank Foundation
