碩士 === 中原大學 === 化學研究所 === 99 === 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
