“…The analyzed electrical conductivity of the adhesives after cooling reached the value of 6 × 10 −2 S/m which is higher than that described in the literature for ECAs based on thermosets. Similar electrical properties (10 −2 S/m) were found for polyolefin HMAs mixed with 5 wt % MWCNT using the same direct melt–mixing approach [ 40 ]. Authors found that the integration of MWCNTs in polyolefin HMAs resulted in the improved adhesion of the bonded joints, however, the significant increase in melt viscosity made it impossible to apply adhesives containing more than 3 wt % MWCNT.…”

“…This suggests the composites based on coPA_B have a lower electrical percolation threshold than the coPA_A based composites. In comparison, an electrical percolation threshold at 0.75 wt % MWCNTs has been reported for HMA based on poly(olefin)s …”

“…These values are similar to those for hot melt poly(olefin)s filled with 2.5 wt % MWCNTs (also NC 7000, Nanocyl) reported by Wehnert et al . in which a rheological percolation threshold was recorded at 0.75 wt % MWCNTs . The difference in the melt viscosity of coPA_B and coPA_A, the former about two times lower than the latter may allow the MWCNTs to be more easily mixed in the polymer matrix achieving rheological percolation at lower MWCNT content.…”

“…Hot melt adhesives have also found a place in the composites industry to improve the bonding strength of hybrid parts (different types of glass/carbon composites) [ 18 ]; improve the interlaminar toughness in lightweight composites [ 19 ]; increase the adhesion between the nanofibrous mat and its supporting woven polyester fabric [ 20 ] or as the conductive adhesive to provide an electrically conductive layer between bonding parts. So far, there are only a few publications describing ECAs based on hot melt adhesives, such as polyurethane [ 21 ], polyolefines [ 22 ], and our previous work on polyamide-based hot melts [ 23 ]. Compared to epoxy adhesives, the main advantages of the hot melts in adhesive bonding are lack of solvent, no requirement of special surface treatment; shorter curing time; lack of weight increase compared to rivets, and recyclability [ 18 ].…”
