Abstract
Magnetic single‐walled carbon nanotubes (SWCNTs) were synthesized in a process consisting of two steps: (a) covalent in situ polymerization and grafting of poly (acrylic acid) (PAA) on the surface of SWCNTs, followed by (b) thermal decomposition of ferric triacetylacetonateto produce magnetite nanoparticles on the PAA‐grafted SWCNTs. It was demonstrated that magnetic nanoparticle–coated SWCNTs dispersed in water by sonication would respond to an external magnetic field. On such functionalization, the reorientation of SWCNTs in an epoxy matrix could be produced using a magnet. This endowed the composites with desirable magnetic and mechanical properties. POLYM.
