Dielectric and Mechanical Properties of 3D Printed Nanocomposites with Varied Particle Diameter

3D printed nanocomposites provide a method for generating high-performance radio frequency devices. Limited work has been done to investigate the influence the nanoparticle diameter has on the performance of 3D printable nanocomposites. We describe here the development of a family of 3D printable nanocomposite inks formulated from nanoparticles with diameters ranging from 30 to 300 nm. Relative permittivity values for the printed nanocomposites were unaffected by nanoparticle diameter whereas loss tangent, glass transition temperature, and elastic modulus were altered. This work provides a framework for designing 3D printable nanocomposites and highlights the importance that nanoparticle diameter plays in formulation strategy.

Automated summary

3D printed nanocomposites have the potential to create high-performance radio frequency devices. However, little is known about how the diameter of the nanoparticles used in these composites affect their performance. This study develops a range of 3D printable nanocomposite inks with nanoparticles ranging from 30 to 300 nm in diameter. The relative permittivity of the printed nanocomposites is unaffected by nanoparticle diameter, but the loss tangent, glass transition temperature, and elastic modulus are altered. This research provides a framework for designing 3D printable nanocomposites and emphasizes the importance of nanoparticle diameter in formulation strategy.
