Fig. 1 shows the XRD patterns for the Na+-Mt and the nanocomposite powders (PPH1, PPH3, PPH4.6, PPH10 and PPH12.5). The d001-spacing of the SPI/Mt nanocomposites prepared through solution intercalation can be calculated on the basis of Bragg's law [d001 = λ / (2sinθ)] according to the peak position. The basal spacing of pristine Na+–Mt was 1.4 nm from a diffraction peak at 2θ = 6.4o, whereas the Mt-free SPI powder shows no diffraction peak in the 2θ range from 1 to 10o. This indicates the soy

The soy protein isolate (SPI)/montmorillonite (Mt) nanocomposites were successfully prepared in aqueous media with different pH values. And then, the SPI/Mt composite plastics with glycerol as plasticizer were obtained via a compression molding process. The electrostatic surface potential has been calculated to investigate the surface charge distribution of the soy protein subunits. The results revealed that the structure of the SPI/Mt nanocomposites was strongly depended on the pH environment during the preparation process. The intercalated na...
