| Research Abstract |
The aim of this project is, (1) to establish the polymer hybrid films with microscopic con-conduction patterns by the insertion electrolytic polymerization of 5-membered heteroaromatics such as pyrrole, thiophene and selenophene within the cylindrical ionic domain of microphase seggregated polyelectrolytes such as Nafion, and (2) to develop elctronic devices such as electro-chromic displays by the combination of said hybrid films and electrochromic materials.
The polymer hybrid films showed anisotropic conduction, i.e., the concuctivity normal to the plane = 10^<0-> ^<-3>S/cm, which that of parallel to the plane was smaller by 3 orders of magnitude, due to the conductive column formation normal to the plane. Rare earth metal diphthalocyanine complex was selected as electrochromic material being able to realize 3 fundamental colors, and by combining this complex with said hybrid films the properties of resulting electrochromic displays were studied. The following 3 methods were employed to prepare the electrochromic displays, (a) casting the complex on the hybrid films, (b) combination of complex LB films and hybrid films, and (c) formation of complex LB films directly on the hybrid films. When the diameter of conduction column in the hybrid films were 10 m, the area of electrochromic responce was rather vague in method (a) such as 40 m. It was improved to 30 and 25 m in (b) and (c), though it is necessary to prepare more smooth and uniform films or to prepare much smaller conduction columns in oreder to obtain better microscopic patters.
