Espínola] Silylation of vermiculite surface with organosilane (H3CO)3SiR, being R is the corresponding organic moieties -CH2CH2CH2Cl, were carried out to yield organofunctionalized nanomaterial, named as VCl. The product reacted subsequently with three aliphatic diamines H2N (CH2)nNH2 (n=2, 4 and 6). The new hybrids were characterized by elemental analysis, infrared spectroscopy, X-ray diffraction and thermogravimetry. The grafting chloro derivates onto surface amounted to 2.1 mmol g-1. The incorporation of alkyl amines was more effective for butyl>ethylene>hexyldiamines. The sequence is in agreement with thermogravimetry and elemental analysis data.
