To improve interfacial adhesion between multi-walled carbon nanotubes (MWCNT) and polymers, the quantitative analysis of MWCNT and its chemical modifications becomes important. MWCNTs are mainly categorized into two structures. One is a tubular type, and many layers of graphite sheets are rolled; this type is commercially available as VGCF<sup>®</sup>. The other is a cup-stacked type, and six-membered rings arranged like cups are stacked up, this type is commercially available as Carbere<sup>®</sup>. In this study, the quantitative surface analysis for the two MWCNTs, which are already graphitized (no residual of metal catalyst), by neutralization titration was carried out. COOH groups are introduced by using the Friedel-Crafts reaction on the defect parts of the two MWCNTs. The introduced amounts of carboxyl groups were determined by neutralization titration. The results suggested that about 17 carboxyl groups per 100 carbons on VGCF<sup>®</sup> surface, and about 22 carboxyl groups on Carbere<sup>®</sup> were introduced, respectively.<br>
