We describe a systematic approach for producing cellulose nanofiber (CNF) nanosheets using the Langmuir–Blodgett (LB) technique. The CNFs were obtained from sulfuric acid hydrolysis of commercially available microfibrillated cellulose. Needle-like CNFs, negatively charged by grafted sulfate groups,...
