Effect of Zinc Oxide concentration on the dielectric properties of 3D Printed Acrylonitrile Butadiene Styrene nanocomposites

Nanocomposites, consisting of Acrylonitrile Butadiene Styrene (ABS) and ZnO of various concentrations were developed by dry mixing the nano filler with the matrix in powder form, followed by melt mixing in an extrusion system, fabrication of filaments and 3D printing of specimens. The effect of the ZnO content on the dielectric properties of the nanocomposite specimens was investigated and as shown, ZnO induces a reduction of the dielectric constant, a behavior that can be employed for tailoring the applicability of ABS in electrical applications.
