Figure 8. Enhancement of k of LCP by controlled processing conditions and by external stimuli. (A) Schematic diagram of (A-i) FDM 3D printing process of a vacuum-tight LCP and print path and, (A-ii) orientations of polymer chain within the printed filament, before and after extrusion. (A-iii) A plot of anisotropic k as a function of concentration of BN fillers in the printed LCP composites.
