TLDR
A review of nylon 6-clay hybrid (NCH) nanocomposites can be found in this paper, where a few wt.-% of silicate is randomly and homogeneously dispersed in the polymer matrix.Abstract:
Summary: More than twenty years have passed since we invented PCN, in which only a few wt.-% of silicate is randomly and homogeneously dispersed in the polymer matrix. When molded, these nanocomposites show superior properties compared to those of pristine polymers. The number of papers on PCN has increased rapidly in recent years, reaching over 500 in 2005 alone. Being pioneers of this new technology, we review its history relative to the following epochal events:
In 1985 we invented nylon 6-clay hybrid (NCH), the first PCN.
In 1989, cars equipped with a NCH part were launched.
In 1997, Gilman found revolutionary fire retardancy in NCH.
In 1997, a PP-clay nanocomposite was prepared using a compatibilizer.
In 1998, a compounding method for producing PCN was completed.
In 2002, Haraguchi invented a revolutionary nanocomposite hydrogel.
So far, only nylon-clay nanocomposites have been used in practice, but other PCN will become increasingly useful in the future.

High-water-content mouldable hydrogels by mixing clay and a dendritic molecular binder
Qigang Wang,Justin L. Mynar,Masaru Yoshida,Eunji Lee,Myongsoo Lee,Kou Okuro,Kazushi Kinbara,Takuzo Aida +7 more
TL;DR: It is reported that water and clay, when mixed with a very small proportion of organic components, quickly form a transparent hydrogel, which can be moulded into shape-persistent, free-standing objects owing to its exceptionally great mechanical strength, and rapidly and completely self-heals when damaged.

Hydrogels for Soft Machines
TL;DR: The recent development of strong hydrogels suggests that it may be possible to design new families of strong gels that would allow the design of soft biomimetic machines, which have not previously been possible.

Mechanical properties of nylon 6-clay hybrid
Yoshitsugu Kojima,Arimitsu Usuki,Masaya Kawasumi,Akane Okada,Yoshiaki Fukushima,Toshio Kurauchi,Osami Kamigaito +6 more
TL;DR: In this paper, the properties of nylon 6-clay hybrids, such as molecular composites of nylon and silicate layers of montmorillonite and saponite, NCH's and NCHP's, respectively, have been synthesized.

TL;DR: In this paper, the carboxyl and amino end groups were attributed to ammonium cations (-NH3+) of nylon molecules, because the difference agreed with the anion site concentration of the montmorillonite in NCH.
