METHOD OF PRODUCING EXFOLIATED NANOCOMPOSITE Russian patent published in 2012 - IPC C08J3/22 C01B33/44 B82B3/00 B82Y30/00 B29C47/10 

FIELD: chemistry.

SUBSTANCE: invention can be used to produce materials used particularly for packaging film with barrier properties, cable sheath and other polymer articles in machine building. The exfoliated nanocomposite polymer/clay is obtained by mixing a matrix polymer and nanofiller - clay, modified with a quaternary ammonium salt. The process is carried out with shear grinding at temperature higher than the melting point of the matrix polymer until achieving nanofiller concentration of 51-70 wt %. The matrix polymer is then added to the obtained mixture until achieving nanofiller concentration of 0.1-30 wt %.

EFFECT: invention increases clay exfoliation efficiency, mechanical properties of the nanocomposite and reduces power consumption when producing said nanocomposite.
