In recent years, photocatalytic technology has received attention for environmental protection. In this study, the usefulness of iron nanostructures generated by anodization was confirmed. Moreover, the synergistic effect of anodized iron (hematite, α-Fe₂O₃) and MWCNT (multi-walled carbon nanotube) was confirmed by methylene blue (MB) decomposition by MWCNT /α-Fe₂O₃ composite material. Electrophoretic deposition(EPD) was used as a method of making the MWCNT/α-Fe₂O₃ composite material. Characterization of the anodized samples and samples after EPD was performed by SEM and XRD, and concentration measurement of MB decomposition was performed using a spectrophotometer. The MB decomposition rate was improved in all the samples with MWCNT and the highest obtained with the MWCNT/α-Fe₂O₃ sample

AbstractSingle-walled carbon nanotube (SWCNT) and multi-walled carbon nanotube (MWCNT) were functionalized with 3,4-diaminobenzoic acid via “direct” Friedel-Crafts acylation reaction in PPA/P2O5 to afford ortho-diamino-functionalized SWCNT (DIF-SWCNT) and MWCNT (DIF-MWCNT). The resultant DIF-SWCNT and DIF-MWCNT showed improved solubility and dispersibility. To improve interfacial adhesion between CNT and polymer matrix, the grafting of ABPBI onto the surface of DIF-SWCNT (10 wt%) or DIF-MWCNT (10 wt%) was conducted by simple in-situ polymerization of AB monomer, 3,4-diaminobenzoic acid dihydrochloride, in PPA. The resultant ABPBI-g-MWCNT and ABPBI-g-SWCNT showed improved the mechanical and electrical properties.
