Nanoclay - an overview | ScienceDirect Topics

Nanoclays are layered silicates with single layer of 0.7 nm thickness, while double layer is 1 nm thick. The interlayer can be modified using surfactants to improve the plasticity and swelling capacity. Surface properties of nanoclays depend on nanosheet charge, nature of surface atoms, and interlayer exchangeable cations.
