Processing and properties of soy protein/silica nanocomposites fabricated in situ synthesis

Abstract: Nanocomposite materials were prepared via glycerol plasticized soy protein as the matrix and in situ fabricated silica as thereinforcing phase. The silica nanoparticles were synthesized in the protein environment by sodium silicate as a precursor. The resulting composites were characterized by Fourier transform infrared spectroscopy (FTIR), wide-angle X-ray diffraction (WAXD), scanning electron microscopy (SEM), dynamic mechanical analysis (DMA), tensile tests, and thermogravimetric analysis (TGA). The results… Show more

“…As expected, the results (Figure 9) show that BG is thermally stable in the temperature range between room temperature and 750 ˚C. The evaporation of water in the temperature range between room temperature and 120 ˚C, the evaporation of glycerol in the range between 120 ˚C and 280 ˚C and the SPI degradation above 280 ˚C were detected by TGA [33]. The total residual mass of approximately 10 wt.…”

“…Cu and Zn nanocluster as well as silicon oxides nanoparticles have been incorporated in SPI matrices to get the reinforced SPI material with improved properties [5,6]. Carbon nanotubes (CNTs) [7], chitin whiskers [8], layered silicate [9][10][11], carbon nanoparticles [12] and silica nanoparticles [13] have been explored as reinforcement materials for SPI. In addition to single composite SPI film, Liu et al has incorporated chitosan and halloysite nanotubes in SPI to fabricate eco-friendly hybrid composite SPI film with high tensile strength [14].…”

“…These functional groups offer the ability to form stable emulsions with lipids (Wei and others ) and to prepare composite materials with silica (Chrissafis and others ). Furthermore, the incorporation of silica as a reinforcing agent substantially improves mechanical properties and thermal stability, as seen for soy protein plastics (Tian ).…”
