- ●
We synthesize a novel and hitherto unreported class of colloidal suspensions.
- ●
These colloidal suspensions are both magnetoresponsive and electrically conductive.
- ●
The dispersed phase consists of MWNTs decorated with different magnetic nanoparticles.
- ●
These colloids have enhanced magnetic response and electric conductivity (up to 169.5 mS cm−1).
- ●
It is a promising new class of material that can be manipulated with a magnetic field.
