Abstract: Rice straw cellulose nanofibrils from the optimal 2,2,6,6-tetramethylpiperidine-1-oxyl oxidation/blending process carrying 1.17 mmol/g surface carboxyls were protonated to varying charged (COO–Na+) and uncharged (COOH) surfaces. Reducing the electrostatic repulsion of surface charges by protonation with… read more here.
