Multiwalled carbon nanotubes (CNT) were functionalized by oxidation with potassium permanganate using a phase transfer catalyst in mild conditions. SU-8 reacted with functional groups, such as –OH and –COOH, of the functionalized carbon nanotubes by opening epoxide groups with the help of surfactants. Ultrasonic irradiation has been employed to prepare SU-8/CNT nanocomposites, using multiple effects such as dispersion, initiation, and activation. The influence of factors such as acidity, reaction temperature, and the nanotube concentration were investigated. The final product is a dark uniform solution. This new UV-curable polymer is expected to have applications in UV coating and microstereolithography for microelectromechanical systems (MEMS) devices.
