The Approach of Electrode Materials on Electroluminescent Fabric
The purpose of this study is to make an electroluminescent fabric, through the dip-coating method, use different layer materials in turns to coating on the conductive fabric, so that the final shape of the fabric can through the electroluminescence principle to achieve the effect of light on the surface. According to the dip-coating procedure, the resin materials in this study are BT2100, phosphor adding with ITK5517, ITK5517, and the outer electrode layer. To confirm the effect of dip-coating method, in the beginning of the study, for each resin material layer and electrode layer (ITO / PET, poly-3,4-ethylenedioxythiophene (PEDOT: PSS), poly-aniline (PANI)) to discussed the coating uniformity and stiffness etc. on the fabric. After the practice to be established, than estimate the polymer of the surface, it is mainly to mixed in different proportions within PEDOT:PSS and PANI, to fill up the defects of conductive interface in the coating method with PEDOT:PSS, through the good surface adhesion of PANI, than make it become more suitable electrode on the electroluminescent fabric. In experimental results, we found that dip-coating can truly achieve the uniform distribution of each sol on the fabric, to obtain better uniformity on the surface, and then the mixture ratio of PEDOT: PSS and PANI in 2:1 and 3:1 , will have the best brightness(17.38lux, 19.86lux) and light uniformity(83.5%, 85.5%).
