Comparison of Carbon Nanotubes and Carbon Nanofibers Based Nanocomposites Prepared with Aid of High Power Ultrasound
The unique morphology and strong inter-tube attraction among CNTs and CNFs makes the dispersion of CNTs and CNFs a big challenge and hence limits their effective use. The comparison of reinforcement efficiency of CNFs and MWNTs in PEI was studied. Ultrasound assisted single and twin screw extruder was used to prepare PEI/CNFs and PEI/MWNTs nanocomposites respectively. The effect of ultrasound on electrical, rheological, morphological and mechanical properties of polyetherimide filled with 1-10wt% of MWNTs and 2-20wt% of CNFs was studied. Ultrasonic treatment caused a reduction in electrical percolation threshold value with a permanent increase of viscosity of treated samples.
