Abstract
Corn-like cellulose nanocrystals/silver (CNC/Ag) nanocomposites were prepared by formic acid/hydrochloric acid hydrolysis of commercial microcrystalline cellulose (MCC), and redox reaction with silver ammonia aqueous solution (Ag(NH3)2(OH)) in one-pot green synthesis, in which the preparation and modification of CNCs were performed simultaneously and the resultant modified CNCs could be as reducing, stabilizing and supporting agents for silver nanoparticles. The influences of the Ag+ ion concentrations on the morphology, microstructure, and properties of the CNC/Ag nanocomposites were investigated. It is found that corn-like CNC/Ag nanocomposites containing Ag nanoparticles with diameter of about 20–40 nm were obtained. Compared to the MCCs, high crystallinity of 88.5 % and the maximum degradation temperature (T max) of 364.5 °C can be achieved. Moreover, the CNC/Ag nanocomposites showed strong antibacterial activity against both Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus. Furthermore, such nanocomposites can act as bifunctional nanofillers to improve thermal stability, mechanical property, and antibacterial activity of commercial poly(3-hydroxybutyrate-co-3-hydroxyvalerate) and poly(lactic acid).
