STRONG PAPER Russian patent published in 2015 - IPC C08L1/02 D21H11/18 D21H13/36 B82B1/00 

FIELD: nanotechnologies.

SUBSTANCE: this invention relates to strong nanopaper. Nanopaper is described, containing clay and microfibrillated cellulose MFC, where clay is a silicate with flaky or plate structure, and where MFC nanofibres and flaky clay are aligned substantially in parallel to the surface of the paper, at the same time nanopaper additionally includes a water soluble binding agent, which is positively charged, when it is in an aqueous solution, and which represents chitosan, and clay includes particles of nanometer range of sizes, besides, length of MFC nanofibers amounts to 5-20 mcm, and the transverse size of MFC nanofibers makes 10-30 nm. The method of production of the above nanopaper is described, Also a coating is described, which includes the above nanopaper, and the method of nanopaper coating application on the surface. The application of the above nanopaper is described.

EFFECT: production of strong nanopaper having improved mechanical and high barrier properties.
