This work investigates the flow characteristic during injection molding process of PC/MWNT nanocomposites especially focusing on jetting. The initial flow pattern while filling has been compared with that of neat and other particle-filled PCs. The experimental results show that the flow of PC/MWNT 5% is comparable to that of PC/GF 15% and PC/CF 10%. It has been found that small amount of filled MWNT causes significant filling difficulty. Based on rheological investigations, this is attributed to extraordinary shear thinning by MWNT fillers.
