Chinese Abstract

有機/無機奈米複合材料是目前熱門的研究主題之一,主要利用有機高分子以及無機物質 (黏土) 兩者之特性相乘而形成奈米複合材料 (Nanocomposites) 。 本論文是利用嵌入技術來合成奈米複合材料,所選用的有機單體為3-Hexylthiophene,將其插入改質之無機層狀黏土層間,於氮氣下進行典型的氧化聚合反應,以合成有機/無機奈米複合材料。應用方面利用電化學方法研究此一有機/無機奈米複合材料之防腐蝕性能,此研究乃藉由導入有效分散之無機層狀黏土以增加有機 Poly(3-Hexylthiophene) 塗層整體之耐蝕性 。 最後再利用氣體透氣量測儀 (GPA) 測試說明材料的阻氣性質大大的提升,以佐證 Poly(3-Hexylthiophene)/Clay 之奈米複合材料之防腐蝕性能。

English Abstract

Abstract A series of Nanocomposite materials that consisted of layered montmorillonite (MMT) clay and poly(3-hexylthiophene) (P3HT) were prepared by effectively dispersing the inorganic nanoclayers of MMT clay in organic poly(3-hexylthiophene) matrix via in-situ polymerization. Organic 3-Hexylthiophene monomers were first intercalated into the interlayer regions of organophilic clay hosts and followed by a one-step oxidative polymerization. The as-synthesized poly(3-hexylthiophene)/ clay lamellar nanocomposite materials were characterized by infrared spectroscopy, wide-angle powder X-ray diffraction, and transmission electron microscopy. Poly(3-hexylthiophene)/clay Nanocomposites in the form of coating with clay loading (e.g., 5%) on cold-rolled steel (CRS) were found superior in corrosion protection over those of conventional Poly(3-hexylthiophene) based on a series of electrochemical measurements of corrosion potential, polarization resistance, and corrosion current in 5 wt-% aqueous NaCl electrolyte. The molecular weights of P3HT extracted from poly(3-hexylthiophene)/clay materials and bulk poly(3-hextythiophene) were determined by gel permeation chromatography (GPC) with THF as eluant. Effects of the material composition on the gas barrier property, thermal stability, flame retardant and mechanical strength of P3HT along with poly(3-hexylthiophene)/clay materials, in the form of both fine powder and free-standing film , were also studied by gas permeability measurements, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), limiting oxygen index (LOI) measurements and dynamic mechanical analysis (DMA).
