1、A minimumnumber of 200 dispersed particles were considered on each fractograph
to identify the size distribution.
2、Weight average PA6 particlesizes were calculated from the distribution of sizes using the followingequation:
3、All samples were gold sputtered prior to observation.
4、Rotational rheological measurements were carried out in anoscillatory mode on a rheometer (Gemini 200 rheometer, BohlinCo., Worcestershire, UK) equipped with a parallel plate geometryusing 25 mm diameter plates at 230 C and frequency range from0.01 to 100 rad s-1.
5、The double percolationwas first introduced in CB filled polymer blends by Sumitaet al. [14]. It refers to the percolation of conductive filler in onephase which also percolates in the blend.
