Molecular interactions in intercalated organically modified clay and clay–polycaprolactam nanocomposites: Experiments and modeling

Thermal degradation of organic matter in the interlayer clay–organic complex: A TG-FTIR study on a montmorillonite/12-aminolauric acid system

“…2. The assignments of each vibration (Table 1) are based on previous reports of Mt and ALA (Katti et al, 2006;Sikdar et al, 2008). The FTIR spectrum of ALA-Mt(Na) exhibited features that are a combination of characteristic bands of Na-Mt and pure ALA ( Fig.…”

“…2c, these bands are absent, and a new band at 1716 cm −1 appears in the ALA inter -Mt(Na) spectrum, which is attributed to the C_O stretching vibration in nonionized carboxyl groups. During the preparation of ALA inter -Mt(Na), the COO − groups reverted to COOH when ALA was added to the aqueous solution of HCl and formed a C_O band in the interlayer Mt-ALA complex (Katti et al, 2006). In addition, the vibration of the interlayer water of Na-Mt at 1636 cm −1 shifts to 1625 cm −1 in ALA inter -Mt(Na).…”

“…Band assignments of the FTIR spectra of Na-Mt, ALA, and Mt-ALA complexes (Katti et al, 2006;Sikdar et al, 2008 Si\O\Si bending of Mt to decompose above 200°C, with a small DTG peak at 224°C (Fig. 3b).…”

PARAFAC Analysis for Temperature-Dependent NMR Spectra of Poly(Lactic Acid) Nanocomposite

“…Nanocomposite is a technique to improve the physical strength, thermal resistance and gas barrier by the dispersion of nanoclay into the polymer (Katti et al, 2006). The improvement of such polymer properties by using nanocomposite is one of the primary areas of interest due to its potential applications.…”

A simple micromechanical approach to predict mechanical behaviour of polypropylene/organoclay nanocomposites based on representative volume element (RVE)

“…MD simulation, on the other hand, can predict more accurately the mechanical properties [16,17] down to the nanoscale level but might get constrained by the integrated large lengths and time scales in the structural analysis of nanocomposites when the scale-up scheme is implemented.…”
