General information
- Short Summary
-
A team of inventors from an established Slovak scientific and research institute and an established Czech scientific and research institute have developed a new method of production of nanofibrillated cellulose.
The preferred cooperation type are commercial agreement or investment agreement. - Full Description
-
The team of inventors from Centre for advanced materials application SAS an from Institute of Physics of Materials CAS set a goal to design produces nanofibrillated cellulose through a mechanical disintegration of cellulose (micro or macro) from any source (pure cellulose, regenerated cellulose, cotton, paper, recycled paper, etc.). The method makes use of a semisolid aqueous-based medium composed of sodium silicate in which the cellulose precursors are dispersed, and machines (such as hammers, punchers, rapid hydraulic presses, etc.) capable of imparting a powerful high-speed deformation, to massively breaks the cellulose chains and chop the fibres down to nanometric size. The sodium-silicate medium is low-cost, non-toxic, and easily removable, besides being a highly efficient storage medium, which keeps the nanosized fibres defibrillated, prevents any post-processing stacking of the nanofibrillated cellulose and protects the nanofibres from degradation (for instance bacterial and fungi degradation).
The institutions are looking for a partner to cooperate with via commercial agreement or investment agreement. - Advantages and Innovations
-
• low-cost, as the synthesis of the fully recyclable waterglass is made up of inexpensive input materials, easy to reproduce and it does not require expensive and sophisticated machines,
• makes use of aqueous medium and therefore eco-friendly and non-toxic,
• effective and efficient for the production of nanofibrillated cellulose and it does not require long time of processing and/or pre-treatments,
• high quality and purity of the produced nanofibrillated cellulose, as the aqueous medium is easily washable,
• scalable and suitable for mass-production, as up to a few kg of product can be produced in one day,
• versatile and flexible, since the waterglass medium can be used for storage or further synthesis of nanocomposite,
• the medium is also a storage medium for the preservation of defibrillated nanocellulose and
• provide the same quality of the final product with less energy consumption and under atmosphere pressure. - Stage of Development

Partner Sought
- Expected Role of a Partner
-
The new method can be used in various areas of nanomaterials, especially to the techniques of synthesis, production, processing and storage of nanofibrillated cellulose, as well as mechanical techniques of nanocellulose production. The nanocellulose prepared by the proposed method of production is suitable for further development of nanocomposites for miscellaneous applications, especially ceramics, metallic and polymeric nanocomposites
The institutions are looking for a partner to cooperate with via commercial agreement (an investor to further develop this technology is sought or a partner to sell this technology to is sought) or investment agreement (a partner for licensing of this technology is sought). - Type and Size of Partner
