Abstract

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.
