Abstract Our ultimate goal of this study is to fabricate buckypaper using multivacancy multi-walled carbon nanotubes (MWCNTs) for filtering ultrafine particulate matter application. First, MWCNTs-Co composites are fabricated by hydrothermal method and heat treatment in atmospheric conditions. Subsequently, cobalt oxide nanoparticles are removed by acid treatment. Through the processes, we can obtain multivacancy MWCNTs with high surface area. In addition, nitrogen-doped MWCNTs with multivacancy defects were obtained via chemical vapor deposition (CVD) method and the multivacancy MWCNTs were mixed with conducting polymer and ionic polymer. These surface modified and polymer composite MWCNTs with multivacancy defects are also employed to fabricate bukcypapes for filtering ultrafine particulate matter (PM 2.5). Here, we present the bukypapers using various multivacancy MWCNTs and filtration experimental data.
