Abstract

Starch nanocrystal (SNC) was prepared by 40°C weak sulfuric acid hydrolysis method. Silver nanoparticles (AgNPs) were simply and quickly reduced in situ on starch nanocrystal by ultrasonic assisted reduction method. UV-vis absorption spectrum verified the existence of AgNPs. The surface modification of AgNPs@SNC was carried out by using 3-aminopropyltriethoxysilane (APTES) with simple structure and low cost to improve its dispersivity in the hydrophobic polymer matrix. Then the success of modification was preliminarily confirmed by the Fourier-transform infrared spectroscopy. Taking Staphylococcus aureus and Escherichia coli bacteria as objects of the study, the antibacterial properties of AgNPs@SNC were also explored, and the test results showed that AgNPs@SNC had certain inhibitory effect on Escherichia coli.
