Abstract/Description: Buckypaper (BP) is a macroscopic aggregate of carbon nanotubes. More specifically, it is an easy-to-handle thin film formed from carbon nanotube networks. Buckypaper contains valuable high mechanical strength, electrical, and thermal conductivity due to their nanoscale dimension and unique structural network. Application examples of buckypaper include for fire and lightning protection, aerospace structures, armor plating, artificial muscles, miniaturization of electrical connections, and etc. The current batch-production method has its own associated limitations and problems, including long process time, cost effectiveness, as well as spilling and improper sonication operation. This research will focus on the analysis of sonication time, examining an effective filtration model that will produce buckypaper at effective rates, and the effect of oven drying on the buckypaper, without sacrificing its conducive, electric, and strength properties. The technical approach used in this work is to study the effect of varying the sonication process time on the quality and properties of the resultant buckypaper samples. During this experiment, buckypaper was created using high, medium, and low sonication times, as well as samples were placed in the oven and compared to those that were not. The study proves that lower sonication time does not prove to be ideal in the maintaining the properties of the buckypaper. The resultant buckypaper did not yield good results due to the tendency of carbon nanotubes to agglomerate with short sonication dispersion time. Additionally, samples that were not placed in the oven after water and methanol baths still proved to have large amounts of surfactant left over, affecting the density and properties of the buckypaper. Poor dispersion and high residual surfactant lead to a decrease in functional properties such as mechanical, electrical, and thermodynamic of the buckypaper. Further investigation into applying those batch-production parameters to the continuous manufacturing process is necessary.
