Characterization of BTO Ceramic Composite Photocurable Resin for Dielectric Applications

Original language description

Stereolithography, as one of the most common 3D printing methods today, can be utilized to advantage the production of complex shapes of functional materials for many applications in electronics. By mixing additives (mostly in powder form) and photopolymer resin, printable materials with specific properties can be prepared: conductors, magnetics, insulators, or dielectrics. This work deals with a novel ceramic composite based on barium titanate(IV). In the experimental part, five different resins (with 0, 5, 10, 15 and 20 wt.% of filler) were prepared and used for the 3D printing of test samples for subsequent characterization: thermal, mechanical, and electrical properties. The dielectric spectroscopy showed that the relative permittivity increased by 89 % against the pure resin for the maximum filling ratio (to εr = 7.96 at 1 kHz, 30 °C), and the increase was significantly higher for elevated temperatures (from εr = 4.70 up to 10.83 at 1 kHz, 60 °C). On the other hand, the material exhibited a decrease in glass transition temperature, and the mechanical properties deteriorated with increasing filler content. Although further improvement is inevitable, the developed material could find a place in a special electronics application like printable dielectric material, e.g., for printing capacitors, dielectric resonation antennas, or functionally graded structures for high-voltage applications. The main advantage is the maintained easy printability and simple preparation method of the composite.
