HANABi - Hybrid approach for architectured bio-based materials

THIN CERAMIC LAYERS DEPOSITED ON A CELLULOSIC SUBSTRATE

CONTEXT

The priority on the preservation of the environment encourages todays research in material science to replace inorganic material as to ensure a higher degree of bio degradability. In parallel, more and more performing materials are required as to fit with miniaturization and lightweight objectives.

TECHNOLOGY

A hybrid approach to combine cellulosic and ceramic materials has produced a new type of material where a ceramic film smaller then 0,04 µm covers one or both sides of a cellulosic substrate. Thanks to an innovation in the desposition of the ceramic film, an agreement between paper and ceramic has been achieved.

The material is water resistant and displays a high thermal resistance. Its over 98% cellulosic material and therefore has an increased biodegradability. It over 99% porosity, its mechanical tightness is increased and its properties include flame retardant.

MATURITY

First demonstrators have been produced to test the basic functionalities of the material.

APPLICATIONS

• Lightweight structures in aeronautics
• Lightweight and insulating structures in civil engineering
• Oxygen barrier and green packaging for agriculture and nutrition
• Membranes for energy & biomedical applications

=> We are looking for partners to carry out feasibility studies on different applications
