制备方法

Commercial cellulose paper can be treated with acid/base to increase porosity. Surface modification with fluoroalkyl trichlorosilanes improves water resistance. Cellulose nanofibrils coating reduces surface roughness for better printing quality. Room temperature processing reduces energy requirements.
