Nanomaterials used to create lightweight, paper-like, flexible ceramic

by • March 28, 2016 • 9s Comments

Materials to manufacture hard-wearing, bendable non-conducting substrates for wearables and other flexible electronics are essential for the future generation of integrated devices. In this vein, researchers at the University of Twente have reformulated ceramic materials so which they have the flexibility of paper and the lightness of a polymer, but yet retain exceptional high-temperature resistance. The new material has been dubbed flexiramics.

High-tech materials such as flexible polymers show promise in this regard, as does boron nitride, and may some day manufacture the cheaper, but extra
brittle insulators – such as those created of traditional ceramics – a thing of the past.
But, the new ceramic material, named flexiramics, may donate these new materials a run for their money as it is not only a tissue-like material which is effortless to fold without breaking, it is in addition reportedly inexpensive and effortless to create.

Made via a proprietary ceramic nanofiber system, the new material has been tested up to 1,200° C (2,192° F) in the laboratory, where it neither burned or melted actually after 24 continuous hours of this heat being applied.

As a substrate (essentially, the base layer) for such things as printed circuit boards, antennas, and radio frequency identification tags, flexiramics displays exceptional dielectric (electrical insulation) properties in the range of 8 to 12 megavolts per meter. Combined with the talent to endure extra
than 2,000 cycles of being bent to a 45 degree angle and back, the flexible ceramic material is in addition exceptionally lightweight at only 0.06 g to 0.09 g per CM3.

Originally created in nanofiber research at the Inorganic & Hybrid Nanomaterials group of the MESA+ Institute of the University of Twente, a new company has been seed-funded by grants to bring the new material to market and appear for new ways to exploit flexiramics’ one-of-a-kind properties.

“I want to inspire (people) to ponder of new ideas and products which never existed before,” said Gerard Cadafalch CEO/CTO of Eurakite, the new company created to commercialize Flexiramics.
