Figure 5. Interactions of nanoclay with polymers.

Figure 5.

(a) Nanoclay can form both physical and chemical bonds with polymer chains via multiple mechanisms. (b) Nanoclay interactions with polymer with different molecular weight. Critical size of polymer chain result in formation of physically crosslinked network. (c) Formation of self-assembled gel when nanoclay is mixed with polymeric binder (hyperbranched polymer). Polymer end group interact with nanoclay and result in formation of mechanically stable hydrogels. Adapted with permission[71] Copyright © Springer Nature Publishing AG.
