General description

Montmorillonite is a layered clay mineral (2:1 phyllosilicate) that belongs to a class of the smectite group. It is a naturally abundant material and is chemically modified by the cation-exchange method for the preparation of polymer nanocomposites.

Application

Montmorillonite has been used as:
  • A nanofiller to improve the mechanical properties of poly(vinyl alcohol) (PVA) film for potential usage in packaging applications.
  • A catalyst in the conversion of polar and non-polar algae oil lipids to biodiesel.


It can also be used:
  • As a nanofiller in the preparation of biopolymer based nanocomposites.
  • In the preparation of Fe3+-montmorillonite, a solid acid catalyst for the synthesis of xanthenedione derivatives.

Other Notes
