因石墨烯與奈米碳管具有優異的機械性質及高強度、高靭性、高硬度、高導熱性、高導電性等獨等性質，成為目前熱門的新興材料，其應用範圍相當廣泛，本研究探討石墨烯與奈米碳管的導電性在導電薄膜方面的探討。

三維的單層奈米碳管經過酸處理後，可得到類似石墨烯的二維平面晶體，本論文使用化學方式製備的石墨烯及酸處理單層奈米碳管，以逐層靜電吸附自我組裝(Layer-by-Layer, LBL)製程成膜，再以浸泡硝酸及加熱處理得到最佳化的導電性薄膜。

利用LBL可控制成膜層數的流程，選定不同層數的石墨烯及單層奈米碳管導電膜，經過優化處理得到最佳參數，再比較兩者之間的穿透度和片電阻。

Grapheneand carbon nanotubes are the emerging reinforcement materials which haveexcellentmechanical properties and high strength, toughness, hardness, head conductivity and electric conductivity. Because of wide range of applications, in this study, we exploit the electric conductivity discussion of the conductive thin film.

Thethree dimensions Single-walled Carbon Nanotubes (SWNTs) after acid treatment could be get a similar two-dimensional crystals of grephene. In this thesis,the conductive thin filmsof graphene by chemical method and SWNTs by acid treatmenthave coated throughLayer-by Layer process. Thin films were doped in the glass substrate through immersion acid and heat process to get the optimizing conductive.

To exploit the thin film formation process coulbd be controlled by LBL method,soselectedthe difference of graphene and SWNTs films by LBL to get the optimal parameters after optimized process,and then compared the correlation between the transmittance and sheet resistance.
