摘要

在本論文中，我們成功的藉由簡單的方法(粒子推疊以及仿生)來製備新穎且先進的防腐蝕塗料。 首先藉由粒子推疊製備超疏水導電高分子，相較於非超疏水導電高分子時具有較佳的防蝕效果。 其次是利用簡單且具高信心度的仿生技術製備超疏電活性發現擁有極佳的防蝕效果。除此之外，超疏水電活性樹酯放置七天後的情況下也具備了長效的防蝕效果，在強酸下也一樣擁有好的防蝕效果。
在第二部分，我們成功利用兩步驟製備聚苯胺/類石墨烯奈米複合材料。單層石墨烯以及類石墨烯是藉由“direct” Friedel-Crafts acylation reaction 所製備而成。接著在將製備完成的類石墨烯分散在1.0 M鹽酸下，再加入APS製備成聚苯胺/石墨烯奈米複合材料粉末。最後的產物利用紅外線光譜儀，廣角XRD，SEM，TEM，電化學測試來做研究。 在此，我們是第一個發表利用聚苯胺/類石墨烯奈米複合材料運用在防蝕塗料上。除此之外，我們還比較了聚苯胺/類石墨烯奈米複合材料以及聚苯胺/黏土奈米複合材料的防蝕效果。結果顯示聚苯胺/類石墨烯奈米複合材料的防蝕效果較傳統的聚苯胺/黏土奈米複合材料的效果要來的好。

Novel advanced superhydrophobic conducting and electroactive polymers have been succefully prepared from poly(2-fluoroaniline)/silica and an easy approach (nanocasting and/or biomimicking method), respectively. The superhydrophobic conducting polymer exhibited good anticorroision property based on a series of electrochemical corrosion measurements performed under saline conditions. It is easy and faithful to prepare superhydrophobic electroactive epoxy (SEE) via biomimicking method. The most important thing is that SEEs show superiorcorroision protection in not only saline condiciton but also extremely condition (strong acid). Moreover, SEEs coatings materials exhibited long-term anticorrosive property.
In second part, the graphene-based polyailine was first utilized as anticorrosive coating materials that was found to be superior in corrosion protection to traditional clay-base polyaniline. This is because the graphene exhibited relatively high aspect ratio than that of clay, which cause the gas would encounter more tortuous path in traversing graphene-based polymer nanocomposites coatings. As such, the graphene-based polyaniline exhibited effective protection the corrosion of metal than that of clay-based polyaniline. Moreover, the functionalized-graphene can serve as conductive-filler for other polymers
