Preparations and characterisation of a nanosilver-loaded aerogel based on nanocellulose

摘要

Cellulose and nanocellulose were used as carriers to prepare composites with antimicrobial and catalytic properties. In this reported study, di-aldehyde cellulose (DAC) was used as a raw material to prepare silver nanoparticles (AgNPs)ano-DAC (DANC) aerogels. The AgNPs/DANC aerogels were loaded with 24.78% nanosilver. The experimental materials were characterised using ultraviolet-visible, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, and Brunauer-Emmett-Teller analysis. The test results showed that the AgNPs loaded on the DANC had particle sizes ranging from 3 to 14 nm, with an average particle size of 5.8 mn. The materials loaded onto the DANC were found to be elemental Ag. The specific surface area of AgNPs/DANC aerogels was 35.40 m(2)/g and the average pore diameter was 19.62 mn.
