An electron-microscopic investigation of an electrochemically polymerized poly (3-methylthienylene) (P3MT) film has been carried out in order to elucidate the cause for the electrical anisotropy of the film.The SEM observation revealed that the film is composed of fibrils of about 50nm in diameter, but, no regular features were seen in their morphology.

The 13C NMR spectrum analysis of electrochemically prepared polythienylene films has been investigated. Both a film doped with ClO−4 ions (PT–ClO4) and an undoped film (PT0) through the electrochemical reduction of PT–ClO4 give only two sharp absorption bands. The spectra of PT–ClO4 and PT0 are remarkably similar to each other in shape. These results demonstrate that both polythienylene are well-defined polymers with only two kinds of carbon atoms which are compatible with dominance of the α–α′ linkage. The upfield shift of the absorption band for PT0 compared with PT–ClO4 is consistent with the increase in electron density through the electrochemical reduction.

3-メチルチオフェンを電解重合する場合の重合条件が, 陽極板上に生成するポリマーフィルム及びその物性に及ぼす影響について検討した. その結果, charge densityの増加に従い, 膜厚はほぼexponentialに増大することがわかった. また, ガスクロマトグラフィーによりchargedensityの増加に伴う重合率変化を追跡した結果, charge densityの増加と比例して重合率も増大することがわかった. これらのことからcharge densityが増すにつれ, ポリマーのフィルムを形成する割合が減少することが確認できた. 更に, フィルムの表面及び断面の状態を走査型電子顕微鏡で観察した. その結果, 重合時のモノマー濃度の高い方がフィルムの構造がより緻密になっていることがわかった. また, フィルムを調製する時のモノマー濃度により物性の異なるフィルムが生成することがわかった.
