氧化石墨烯摻雜CNTS制備透明電極及其在OLED中的應(yīng)用.pdf

1、學(xué)位論文的主要創(chuàng)新點f燃掣緲一、系統(tǒng)地研究了不同濃度的氧化石墨烯片層對單壁碳納米管進行摻雜、制備透明導(dǎo)電薄膜來提高薄膜光電以及界面的諸多性能，極大提升了薄膜的附著力并探索了其機理。二、通過高速離心的方法將氧化石墨烯不同片徑進行分離，得到不同片徑的氧化石墨烯對單壁碳納米管進行摻雜，探究了載流子在一維二維碳納米材料中的傳導(dǎo)機制。三、將制備得到的石墨烯摻雜碳納米管透明導(dǎo)電薄膜應(yīng)用于有機發(fā)光二極管OLED器件中，通過二維材料的摻雜優(yōu)化，電極表面

2、功函數(shù)得到調(diào)控，界面載流子注入勢壘降低，使得器件開啟電壓減小，同時電極的平整度以及潤濕性改善使得界面虛接減少，載流子注入更均一，發(fā)光更加均勻。AbstractWiththeincreasingrequirementofflexibledisplaydevices，touchpanels，SolarCellsandportableenergystoragedevices，suchasrisingdemandforflexibletrans
