From liquid crystals to 3D dielectric materials – 3Dielectric

Submission summary

Dielectric materials are electrical insulators that can be polarized by an applied electric field. They are among others highly demanded for producing capacitors, which are the most important energy storage components in electronic circuit technology. The ability to print dielectric materials and capacitors on planar surfaces or 3D objects is the key to realize fully-printed electronics. Due to the low energy density, printed capacitors occupy significant printing area and weight in the entire printed electronics. Today, it remains challenging to develop novel dielectric materials with printability and high energy density.

In this project, we address this issue by proposing a new generation of 3D dielectric materials based upon an original concept, i.e., water-based composite inks comprised of polymers and liquid crystalline nanosheets. By contrast to competing projects with randomly mixing inorganic/organic hybrids, our concept will lead to larger energy density by generating stronger polarization at higher electric fields thanks to the deterministic multiscale control of composite structure by a combination of self-assembly and digital microfabrication. This project profits from the expertise of the laboratory CRPP in soft matters. It expands the current research scope by adding new processing, new functionalities and applications of soft matters.

To reach the objectives of the project, we constitute a multi-disciplinary team of chemists, physical chemists and material scientists, who will cover the tasks of the project. The production of entirely inkjet-printed capacitors at the lab scale will be validated and their technical specifications will be evaluated, so that the developed ink materials and printed capacitors of the project could in a short-medium-term be developed towards actual markets.
