Preparation of protein-silicate hybrids from polyamine intercalation of layered montmorillonite.


Hybrids of the model BSA protein and layered silicate clay with d spacing of approximately 62 A were prepared from either direct or stepwise intercalation. The pristine montmorilloinite (Na+-MMT) was first modified by poly(oxyalkylene)-amine salts (POP- and POE-amine) of 2000 g/mol Mw to a gallery-expanded silicate (d spacing=53 and 18 A, respectively… (More)
