| Outline of Final Research Achievements |
Transparent conductive films have been used for the touch panels, of which main material is a semi-conductive inorganic oxide, but it has been required to be replaced by new materials because of the shortage of its flexibility. Since conductive polymer PEDOT:PSS has a shortage of its conductivity, several kinds of additives for itd conductive enhancement have been studied. Phenol derivatives are effective for the conductive enhancement. However it has not been made clear what phenol derivative shows the highest conductive enhancement ability and how it works on the conductive enhancement of PEDOT:PSS. This study disclosed that phenol derivatives with the solubility parameter (SP) values ranging from 14 to 16 have a higher conductive enhancement ability, and that electronic interaction between PEDOT:PSS and a phenol derivative followed by the change of physical properties such as the size and surface charge of PEDOT:PSS nano particles result in the conductive enhancement.

| Academic Significance and Societal Importance of the Research Achievements |
PEDOT:PSSの導電性向上作用が大きいフェノール誘導体のSP値は14～16にあり、さらにフェノール誘導体とPEDOT:PSSとの相互作用により起こるPEDOT:PSS粒子特性の変化が導電性向上に関係する。導電性向上添加剤を探索する上で、添加剤のSP値及びPEDOT:PSSの粒子特性の観点から検討すること重要であることを示唆したので学術的意義は大きい。また、フェノール誘導体を用いればPEDOT:PSSの導電率を二桁ほど向上させることが可能となるので、本検討系が現行透明導電材ITOの代替材として有望で社会的意義は大きい。
