“…The I-V curves show that the bar-shaped channel fabricated using parallel scanning was 1000 times more conductive than that fabricated with perpendicular scanning (Figure 3 b). The three-orders-of-magnitude difference in electrical conductance matched with the high anisotropy in electrical conductivity of CNTs in directions parallel with or perpendicular to the CNT axis, [ 35 ] which further confi rms the strong orientation alignment of the MWNTs inside the polymer. Figure 3 c shows the electrical conductivity of the MTA composite polymers with respect to different MWNT concentrations.…”

Laser-directed assembly of multiwalled carbon nanotubes (MWNTs) in 3D space is investigated via a two-photon polymerization technique. MWNT-thiol-acrylate (MTA) composite resins are developed with high MWNT concentrations up to 0.2 wt%, over one order of magnitude higher than previously published work. Significantly enhanced electrical and mechanical properties of the 3D micro-/nanostructures are achieved. Microelectronic devices made of the MTA resins are demonstrated.

“…In anisotropic composite, fillers exhibit some certain orientation, which results in unique macroscopic properties, and there are various application requirements in the fields of biomedicine, electromagnetic shielding, stealth technology, and aircraft fuselage materials. Orientations by shear force, magnetic field, electric field, copolymer thermal gradient self‐assembly, solvent evaporation driving, and the like could be used to prepare anisotropic polymer composites …”

It is well known that 3D printed parts prepared by fused deposition modeling (FDM) exhibit large anisotropy of mechanical properties. In this article, poly(lactic acid; PLA)/carbon fiber (CF) composites with different built orientations (X, Y, Z) were prepared by FDM. The effects of printing temperature, speed, orientations, and layer thickness on the mechanical properties of the composites were systematically investigated. The mechanical properties of PLA/CF composites show more significant anisotropy. The orientation of the fibers along the printing direction is displayed by scanning electron microscopy. Printing parameters bring almost no effect on mechanical properties of the X‐construct oriented specimen, and bring obvious effect on those of the Y‐construct oriented specimen and Z‐construct oriented specimen. According to the analysis, carbon fiber can amplify this anisotropy from layer fashion, and the key factors from printing parameters are porosity and bond strength between fuses. © 2019 Wiley Periodicals, Inc.
