Resum
Stoichiometric ionic complexes of bacterial poly(c-glutamic acid) with the cationic N-octadecyland N-docosyl-N,N,N-trimethylammonium surfactants were mixed with alkylammonium modified bentonite (Cloisite 30B) to generate hybrid compounds covering a wide range of clay/polymer compositions. The structure of these compounds was examined by XRD and cryoTEM, which indicated extensive penetration of the biopolymer into the nanoclay galleries with widening or even destruction of the layered arrangement...
