中文摘要 | 層狀磷酸鉛主體具有酸基且其層間僅有微弱約凡得瓦力,因而可嵌入 苯胺單體。層中苯胺可氧化還原聚合為聚苯胺(Polyaniline),此複材導電與否與主 就結構有關;氫型磷酸鋯層中之聚苯胺以emeralsine salt(PAN-2S)為主。而鈉型磷酸 鋯層中之聚苯胺則以emeraldine base(PAN-2A)為主。由淨層距、纖維狀之聚苯胺、 分子量、電子順核磁共振光譜、核磁共振光譜及整體導電度降低,可說明聚苯胺 嵌入主體層中。氫型磷酸鋯層中之聚苯胺其導電活化能為0.087eV,而此複材之 導電機構為跳躍導電。 |
英文摘要 | The intercalation of aniline by the layered compound α- zirconium phosphates have beenexamined. After addition of ammonium peroxodisulfate, the loaded aniline were polymerized topolyaniline (PAN). The structures of PAN in proton form and sodium form zirconium phosphate hosts were shown to have the typical spectral features of emeraldine salt and emeraldinebase respectively. Intercalation of PAN in zirconium phosphates were confirmed by the varition of the clearance space, the fibrous isolated PAN, the resonances in NMR and EPR andthe reduction of bulk conductivity. From the temperature dependence of the conductivity measurements, the height of the potential barrier (Ea) is 0.087 eV and the conduction mechanismfor PAN-HZ is possibly a hopping conduction. |
