Cellulose acetate

Cellulose acetate was developed in the late 19th century as part of an effort to design industrially produced fibres based on cellulose Treatment of cellulose with nitric acid had produced cellulose nitrate (also known as nitrocellulose) but the difficulties of working with this highly flammable compound encouraged research in other areas In 1865 Paul Schtzenberger and Laurent Naudin of

Synthesis and Characterization of a High Flux

06 06 2019The pristine cellulose acetate membrane exhibited a pure water flux of ~15 L m − 2 h − 1 after the compaction of the membrane was completed Incorporation of 0 1 wt % CNF into the membrane did not change the water permeability of the membrane probably due to the very low content of the CNF Interestingly a noticeable change was found when 0 3 wt % CNF was incorporated into
