Schematics of carbonaceous filler networks in the PLA foams. The solid curves and the black dots represent CNTs and CB, respectively. The solid arrows indicate broken or invalid pathways of the CB networks, and the hollow arrows ‘dead’ ends or branches of the CNTs located at the broken cell wall, which have no contribution to the conductive networks (adapted from reference [142]).
