在本工作的第一章中對(duì)納米復(fù)合物進(jìn)行了介紹。最近,各研究小組對(duì)納米材料的研究工作做了計(jì)劃和開(kāi)展。因?yàn)榇蠖鄶?shù)的材料制備成納米材料之后,其性能與原材料與原材料呈現(xiàn)出很大的差異。在目前的研究中,石墨應(yīng)該是一種處于最前沿的納米材料,由于石墨烯具有令人驚嘆的物理和電學(xué)性質(zhì),引起了電化學(xué)工作者的極大關(guān)注。石墨烯材料已經(jīng)在很多電化學(xué)研究中體現(xiàn)出了優(yōu)異的物理化學(xué)性能。從而受到了廣泛的關(guān)注。石墨烯是一種具有非常精細(xì)結(jié)構(gòu)的碳納米材料,碳原子間采用sp2雜化的方式牢固地堆積在呈二維單層的蜂窩狀平面晶格中。由于其高比表面積,高精確的孔徑,高的熱和機(jī)械強(qiáng)度,小的電子傳輸阻力,大的吸附能力以及很好的化學(xué)惰性,而被公認(rèn)為是首選的研究對(duì)象。為了提高它的適用性以適應(yīng)其它方面的應(yīng)用,已經(jīng)有將聚合物復(fù)合到到石墨烯上的很多報(bào)道。噻吩聚合物(聚噻吩)與石墨烯復(fù)合后,不僅改變了碳材料的導(dǎo)電性而且在碳的表面上提供了更多活性基團(tuán),這大大擴(kuò)展了石墨烯的電化學(xué)性能。在第二章中,我們介紹了我們的主要工作。我們主要介紹了采用電化學(xué)氧化聚合的方法制備聚噻吩的方法。同時(shí)介紹了石墨烯-聚噻吩復(fù)合材料修飾電極的制備以及對(duì)其性質(zhì)進(jìn)行表征,利用該電極對(duì)布...
