Ionic coupling of bacterial poly(γ-glutamic acid) (PGGA) with alkyltrimethylphosphonium surfactants is reported to render comb-like PGGA complexes with a biphasic-layered structure displaying periodicity at the nanoscopic scale. In this work, nanocomposites made of PGGA and montmorillonite, and covering a wide variety of compositions, are...
