Injection moulding of polymer–carbon nanotube composites
C.Y. Lew, C. Dewaghe and M. Claes, Nanocyl S.A., Belgium
The electrical resistivity of a polymer–carbon nanotube (CNT) composite is sensitive to injection moulding parameters and, therefore, imparts flexible property design to meet different application requirements. In this chapter, the authors attempt to identify via a 2i factorial design of experiment the interactions between injection parameters, volume resistivity, surface resistivity and surface finish, using a low viscosity polycarbonate (melt flow index, MFI, 38 g/10 min) and then verify the interactions in more detail using a higher viscosity polycarbonate (MFI 20 g/10 min). Results indicated that the volume ...
