Abstract

The present work describes the preparation of nano-lignin particles from calcium lignosulfonate (CL). The nano-lignin was fabricated from colloidal lignin-polyacrylamide complexes via self-assembly. The sizes of the nano-lignin particles were examined by dynamic light scattering (DLS) and scanning electron microscopy (SEM). The results indicated that the average particle size of the prepared nano-lignin was approximately 100 nm. In addition, the obtained nano-lignin exhibited enhanced fluorescence intensity when compared with the original lignin, which might represent a potential application of this nano-particle product.

摘要

本研究描述了从木质素磺酸钙（CL）制备纳米木质素颗粒的过程。纳米木质素是由胶体木质素-聚丙烯酰胺复合物通过自组装制备而成的。通过动态光散射（DLS）和扫描电子显微镜（SEM）对纳米木质素颗粒的尺寸进行了检测。结果表明，所制备的纳米木质素的平均粒径约为100 nm。此外，与原始木质素相比，所获得的纳米木质素表现出增强的荧光强度，这可能代表了这种纳米颗粒产品的潜在应用。
