This essay is divided into two parts. In the first part , a series of polyimide/clay nanocomposites were successfully prepared. We used two different intercalated agents{4,4’-Oxydianiline(ODA) and Hexadecyltrimethyl ammonium bromide（C19H42NBr）} to modify clay. The polyimide/clay nanocomposite materials were prepared by effectively dispersing the inorganic nanolayers of MMT clay in to the organic polyimide <a href="http://www.ntsearch.com/search.php?q=matrix&v=56">matrix</a> via a thermal imidization up to 300℃. The as-synthesized nanocomposite materials were characterized by FT-IR, XRD and TEM. The nanocomposite material , enhanced better thermal properties , mechanical strength and gas barrier properties.
The second part is concerned with the relative to the bulk polymer preparation and properties of Acrylonitrile-Butadiene-Styrene /clay (ABS/clay) nanocomposites materials .We used melt intercalation approach to prepare ABS/clay nanocomposites.
The as-prepared nanocomposite materials were also characterized by FT-IR, XRD and TEM. The properties of ABS/clay nanocomposite materials also exhibited much better performance than that of neat polymer.
