摘要：
Cellulose acetate (CA) nanofibers were embedded with aggregated silver-nanocubes (AgNCs) by a coaxial electrospinning method. AgNCs were dispersed with CA and acetone-dimethylacetamide (DMAc) as a precursor solution, and AgNCs aggregation was induced with acetone. The nanofibers have a remarkable surface-enhanced Raman scattering (SERS) activity due to the strong plasmon coupling between neighboring AgNCs, which is 4 times of the monomeric-AgNC/CA sample. As a result, 0.1 nmol/L p-aminothiophenol (p-ATP) and 10 nmol/L methyl parathion can be identified, respectively. The nanofibers generate large-area homogeneous SERS signals with a relative signal deviation of less than 12% over 1 mm×1 mm area due to the homogeneous adsorption of target molecules. It is thus indicated that aggregated-AgNCs/CA nanofibers have a promising potential in SERS-based detection of organic pollutants in aqueous solutions. © 2021, Editorial Department of Journal of the Chinese Ceramic Society.
