Publication number: 20100279001Abstract: Disclosed are a carbon nano-tube (CNT) thin film treated with chemical having an electron withdrawing functional group and a manufacturing method thereof. Specifically, the CNT thin film comprises a CNT composition to be applied on a plastic substrate. The CNT composition comprises a CNT; and chemical connected to the CNT and having an electron withdrawing functional group. In addition, the method for manufacturing a CNT thin film comprises steps of preparing a CNT; treating the CNT with chemical having an electron withdrawing functional group; mixing the CNT treated with the chemical with a dispersing agent or dispersing solvent to prepare a CNT dispersed solution; and forming a CNT thin film with the CNT dispersed solution. According to the CNT thin film and the manufacturing method thereof, a resistance of an electrode is decreased to improve the electric conductivity of the electrode.Type: ApplicationFiled: February 14, 2008Publication date: November 4, 2010Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Hyeon Jin Shin, Seonmi Yoon, Jaeyoung Choi, Young Hee Lee, Seong Jae Choi, Soo Min Kim
