New devices and structures for Flexible Hybrid Electronics will depend on advances in multifunctional polymer substrates, inks, and printing approaches for rapid manufacturing. For example, the manufacturability of printed RF and MW electronics will be achieved by the development of scaled processes for the creation of tunable dielectric substrates and conductive patterning. In this work, the flexible tunable substrates were created by embedding barium strontium titanate (BST) nanoparticles in a variety of polymer matrices using the twin screw extrusion process. Extruded sheets were fabricated for printing using a continuous process. Dielectric properties were measured as a function of BST loading over the frequency range of 1-10 kHz. The dielectric constant of the composite substrates increased with increasing volume fraction of BST. The extruded sheets were characterized by contact angle for surface and wetting properties, by scanning electron microscopy to evaluate the dispersion of the filler into the polymer matrices, and for surface roughness. The development of a scalable manufacturing process for substrate fabrication and printing will lead to the design of the next generation adaptive printed RF and microwave components and devices for future asset monitoring systems.
