In this study, we investigate the multiwall carbon nanotubes (MW CNTs) in IsoPropanol (IPA) solvent with different sonication conditions, membrane filter size for paper with areal density of 3 mg/cm2 with different sizes such as 4, 10, 20 cm in diameter and large scale of 30×30 cm2 . It is observed that the dispersion of CNTs are good and the thickness, conductivity are uniform over whole sample for above sizes. We also can get the highest conductivity of buckypaper was ×103 S/m in 30 minutes. It is found that the higher sonication power and higher sonication time are better for buckypaper. | Communications in Physics, Vol. 28, No. 3 (2018), pp. 217-224 DOI: STUDY TO FABRICATE THE LARGE SCALE BUCKYPAPER BASED ON CARBON NANOTUBES DOANH TU TIEU1 , MY KHANH NGUYEN3 , THAM THI HONG NGUYEN1 , THANH VO KE NGO1,2 AND QUYET HUU DO1,† 1 Sai Gon Hi Tech Park Labs, Sai Gon Hi Tech Park, District 9, Ho Chi Minh City, Vietnam 2 Institute for Computational Science and Technology, SBI building, Quang Trung Software City, Tan Chanh Hiep ward, district 12, Ho Chi Minh city, Vietnam 3 University of Natural Science, 227 Nguyen Van Cu, District 5, Ho Chi Minh City, Vietnam † E-mail: Received 25 September 2017 Accepted for publication 20 July 2018 Published 31 August 2018 Abstract. Carbon nanotubes (CNTs) have attracted great attention because of their unique structural, electrical, mechanical and thermal properties. Then CNTs have potential application as thermal pads, electrodes for batteries and supercapacitors, especially binder-free electrodes. The major challenge is to fabricate the large scale electrode with the uniform thickness, electrical property. The large scale CNTs buckypaper can be fabricated via vacuum filtration technique. The characteristics of CNT dispersion and buckypaper depend on variety of factor such as sonication power, sonication time, dispersant. . . . In this study, we investigate the multiwall carbon nanotubes (MW CNTs) in IsoPropanol (IPA) solvent with different sonication conditions, membrane filter size for paper with areal density of 3 mg/cm2 with different sizes such as 4, 10, 20 cm in diameter and large scale of 30 × 30 cm2 . It is observed that the dispersion of CNTs are good and the thickness, conductivity are uniform over whole sample for above sizes. We also can get the highest conductivity of buckypaper was × 103 S/m in 30 minutes. It is found that the higher sonication power and higher sonication time are better for buckypaper.
