有機導電高分子不但具有一般高分子的特性,如質輕、堅韌、易加工等優點,又具有傳統高分子所沒有的導電性,無機物則是性質較剛硬,熱穩定度好,所以有機無機複合材料於是成為近來的一個研究方向。藉由無機物的混入來增強複合材料的剛性與熱穩定性,或者將有機物混入無機物中,來製備質輕且具韌性的複合材料,這些複合材料可能沒有個別材料的缺點,而擁有個別材料的優點。本研究於是利用分子自我組合的方法,試著將水溶性聚苯胺(PAPSAH,
PSA,PAPSA)與V2O5混合,來合成有機物/無機物捺米複合材料,探討水溶性聚苯胺添加量與材料導電性的關係,並且探討水溶性聚苯胺在層狀化合物內的結構與排列狀況。由水溶性聚苯胺C-N鍵之紅外光譜吸收的偏移,ESR圖譜中V2O5之V原子由V+5被還原成V+4,另外由ESCA圖譜中N原子和V原子binding energy的位移,可以知道水溶性聚苯胺和V2O5之間確有作用力的存在,變溫X-ray的結果則顯示,聚苯胺可能存在於V2O5結構中之孔隙內。導電度的測試結果可以發現,複合物中聚苯胺的添加量越多,有助於提昇複合物的導電性。另外也對這一系列的複合物作電化學性質的測試,由複合物的電化學測試,得知不同計量比之複合物會有不同的氧化還原電位,且顏色也會有不同的變化,在經過了多次的氧化還原循環後,導電複合物膜依然未受損,具作為電變色顯示器材料的潛力。

Organic conducting polymers have the properties of the organic polymers. Such as, light weight, plasticity and processability. On the other hand, Inorganic materal in general is hard and good thermal stability. Therefore, the organic-inorganic hybrid materials have been the subjects of intensive research, due to these hybrid materials may have the properties, which can not obtain from the individual components. In this dissertation, we investigated the synthesis and physicochemical properties of water soluble polyaniline (PAPSAH, PSA, PAPSA) - V2O5 xerogel nanocomposites. Various spectroscopic (IR,ESR,ESCA) data indicated that N atoms in polyaniline coordinated to the V atom in V2O5. X-ray data showed that water soluble polyaniline existed in between the V2O5 layers. The room temperature conductivity of these nanocomposites increased with increasing the mount of water soluble polyaniline in hybrid material. From the electrochemistry data, we know that different stoichiometry of materials had different oxidation/reduction potential and the corresponding color changes. Furthermore, after several oxidation/ reduction cycles, the composite films remain intact. They showed a good potential to be applied in the electrochromic display devies.
