There is continuing interest in the growing family of nanocellulosic materials prepared from plant cell wall material. While most of the research on cellulose nanocrystals has focused on the product of sulfuric acid hydrolysis stabilized by surface sulfate half-esters, cellulose nanocrystals with surface carboxyl groups have also been prepared by oxidation of lignocellulosic materials with ammonium persulfate. The major difference is that the persulfate oxidation leads to nanocrystals stabilized by surface carboxyl groups. Some properties of cellulose nanocrystals from cotton and wood, prepared by persulfate oxidation, are compared with those observed for nanocrystals prepared by sulfuric acid hydrolysis. Evidence from polarized light microscopy showed that the nanocrystal suspensions prepared by persulfate oxidation also form chiral nematic ordered phases in water.
