摘要

SiO2 nanoparticles with different sizes were prepared under ultrasonic irradiation and incorporated with soy protein isolate (SPI) films. The morphology, size distributions and stability of the obtained SiO2 nanoparticles were characterized by transmission electron microscopy and zeta potential measurements. The effects of differently sized SiO2 nanoparticles on the morphological, physical, water barrier, oxygen barrier, mechanical and thermal properties of the SPI-based films were investigated. The results showed that the moisture content and total soluble matter values of the SPI-based films decreased with decreasing SiO2 nanoparticle size and showed the lowest values of 16.70 +/- 0.40% and 30.44 +/- 0.06%, respectively, with a minimum particle size of 8.11 nm. Smallest particle sizes not only improved the contact angle and tensile strength by 21.12% and 17.65%, but also reduced the water vapor permeability and oxygen permeability of the SPI films by 11.79% and 9.66%, respectively. Furthermore, the addition of SiO2 enhanced the thermal stability of the SPI films.
