It is shown here that on account of ionic repulsion between charged surface groups , slightly phosphorylated CNCs ( P - CNCs , average dimensions 31 +/- 14 x 316 +/- 127 nm , surface charge density = 10 . 8 +/- 2 . 7 mmol / kg cellulose ) , prepared by controlled hydrolysis of cotton with phosphoric acid , are readily dispersible and form stable dispersions in polar solvents such as water , dimethyl sulfoxide , and dimethylformamide .
 Chemical: phosphoric acid; Chemical: dimethyl sulfoxide; Chemical: dimethylformamide
