Manufacturer's Description

Sigma-Aldrich Materials Science, in collaboration with Nanocor Corporation, is pleased to offer a line of montmorillonite nanoclays. To make the clays compatible with hydrophobic polymers, they are surface exchanged with alkylammonium cations; the five Nanomer® I clays differ in the chemical nature of their surface bound cations. Cationic clay layers of the Nanoclay, Nanomer® PGV (Product No. 682659) are hydrophylic and can be dispersed in aqueous polymers. Nanocomposite properties are highly dependent on the chemical nature of organic cations and polymer chains, as well as the method used to disperse (process) the clay to form the nanocomposite.2 Depending on the polymer to be modified, and the property enhancement you are seeking, we offer product information on our nanoclays below. The table also lists codes to product application datasheets that contain suggestions on how to form nanocomposites. We hope our suggestions will help you. We also hope that having the Nanoclays conveniently available in our catalog will help you explore new methods and applications in this exciting area of materials research.
