Permittivity of BaTiO3 polymer composite with differing particle size distribution

Schumacher B., Geßwein H., Hanemann T., Haußelt J., Forschungszentrum Karlsruhe GmbH, DE

In previous works the authors presented the possibility to raise the permittivity of polyester-reactive-resin composite materials by using thermal treatment steps to optimize the crystal structure of a nano-powder before incorporating it into the composite. [...]

Influence of the crystallite size of BaTiO3 on the dielectric properties of polyester reactive resin composite materials

Schumacher B., Geßwein H., Hanemann T., Haußelt J., Forschungszentrum Karlsruhe, DE

Today’s electric equipment has to be small in dimension and rich in functionality to be successful with the customer. The available surface area on today’s printed circuit boards (PCB) is decreasing as a result and [...]

Material Properties of Polymer Nanoparticle Composites for Micro Optical Applications

Ritzhaupt-Kleissl E., Böhm J., Haußelt J., Hanemann T., Forschungszentrum Karlsruhe, DE

Nanosized ceramics, highly dispersed into polymer matrix materials, are widely being discussed for the modification of polymer properties. For applications in microsystem technology, the modification of the polymers’ optical and mechanical properties is of certain [...]
