“…Chen et al 5 reported that the amount of carboxyl groups on the MWCNTs can be well controlled at the interface of a cocontinuous polystyrene (PS)/poly(methyl methacrylate) (PMMA) blend to design conductive polymer composites with ultralow percolation threshold. Moreover, the formation of the percolation nanofiller network in one polymer phase (self‐networking ability) may induce the cocontinuous morphology of immiscible polymer composites 14–17 . Nuzzo et al 16 discovered that adding organoclay, sepiolite, and CNTs to immiscible PLA/PA11 polymer composites induced cocontinuous morphology.…”

[14][15][16][17] Nuzzo et al 16 discovered that adding organoclay, sepiolite, and CNTs to immiscible PLA/PA11 polymer composites induced cocontinuous morphology. They proposed that nanoparticles' ability to decrease interfacial tension between filled PA11 and continuous PLA played a critical role in this phenomenon.…”

The addition of graphene nanosheets (GNSs) into immiscible polymer composites to induce the cocontinuous morphologies shows potential application in reinforced nanocomposites and conductive polymer nanocomposites. In this work, immiscible high density polyethylene (HDPE)/polyamide 6 (PA6)/GNS composites were prepared via melt mixing. The electrical and rheological property of HDPE/PA6 composites filled with various GNS contents according to different viscosity ratios and mixing orders were investigated to reveal the double percolation effect via percolation scaling laws, and compared with those of HDPE/GNS and PA6/GNS composites. The morphology and GNS dispersion state of HDPE/PA6/GNS composites were examined via transmission electron microscopy and scanning electron microscope. Most of the GNS were selectively located in the PA6 phase of HDPE/PA6/GNS composites. The GNSrelated network and mixing order played important roles in the cocontinuous morphology formation and performance of HDPE/PA6/GNS conductive composites. Moreover, the addition of GNS also affected the crystallization kinetics and mechanical property of HDPE/PA6/GNS composites.

In order to improve the flame retardancy and antistatic properties of polyamide 6 (PA6) at as low amount of additives as possible, an integrated-functional additive was synthesized by 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and multiwalled carbon nanotubes (MWCNTs). The results showed 2 wt% of DOPO-MWCNTs distributed in PA6 formed an electric network and decreased volume resistivity sharply to 3.1 × 10 8 Ω cm. In other words, it helped PA6 to get to the percolation threshold of semiconductor. By using of 3 wt% DOPO-MWCNTs, the severe dripping in burning of PA6 was almost controlled. The possible reason was also ascribed to the network formed by evenly dispersed DOPO-MWCNTs, which strengthened the char structure and held severe dripping of PA6. As a result, the heat and smoke release were also suppressed obviously. The most important is that CO release was about half cut in CONE test.
