Electrophoretic Deposition of Carbon Nanotubes onto Carbon Fiber Laminated Composites: Effect of Suspension Medium, Deposition Voltage, and Time

Multiwalled carbon nanotubes-Carbon Fiber (MWCNT–CF/) epoxy laminated composites are widely used in many applications, and electrophoretic deposition (EPD) is a hybridisation method that is often used. This research focuses on improving the technique by optimising the input parameters to obtain comp...
