Abstract
We have found that polysaccharide polymers such as sodium alginate and agar can be convenient dispersion agents for vaper grown carbon fiver (VGCF). VGCF/sodium alginate composite films and VGCF/SiC composite ceramics with good uniformity and dispersion were prepared by utilizing the resulted dispersion solution. The dispersed composition of VGCF into SiC led an increase in flexural strength, fracture toughness and electric conductivity of SiC. In addition to these results, the magnetic properties of metal ions (Fe3+, Gd3+) bound to poly (acrylic) acid-modified multiwalled carbon nanotube (MWCNT) were discussed.
