Effects of Size and Dispersity of Microcrystalline Celluloses on Size, Structure and Stability of Nanocrystalline Celluloses Extracted by Acid Hydrolysis
[en] Nanocrystalline celluloses (NCCs) were separated from four commercial microcrystalline celluloses
(MCCs) by an acid hydrolysis–sonication treatment. Transmission electron microscopy
(TEM), atomic force microscopy (AFM), Fourier transform infrared (FTIR) spectrum, X-ray
di®raction (XRD) and thermogravimetric analysis (TGA) were conducted to investigate the
NCCs. MCCs with di®erent morphologies and particle sizes showed di®erent aggregation degrees.
The aggregation of MCCs followed the order MCC1 > MCC3 > MCC2 > MCC4, which is the
same order of the heights of the resulting NCCs. The best uniformity and thermal stability were
characterized for NCC3, which was produced by MCC3 with smallest original particle size and
good dispersity among the four MCCs. This result suggests that both the original particle size and
dispersity of MCCs had signi¯cant e®ects on separated NCCs.
