Abstract
Filters play a vital role in development of
environmentally friendly processes. Cellulose provides a
biodegradable and versatile alternative for synthetic
filter materials. In this study, different kinds of
nanocellulosic materials were utilized to prep.
stimuli-responsive filters for water purifn.
Nanocellulosic materials were prepd. mech. from
unmodified and TEMPO-oxidized pulp. TEMPO-oxidized
cellulose contains a high amt. of carboxylic groups,
which can be used to scavenge metal ions. Nanocelluloses
were grafted using N-isopropylacrylamide (NIPAM) to
introduce temp.-responsive functionalities. Poly(NIPAM)
is a temp.-responsive polymer, which undergoes a change
in hydration state at 32 °C. Solvent casting and coating
methods were evaluated for prepn. of free-standing and
support material-based filters, resp. Filter stability,
permeate flux, morphol. and particle and ion retention
were characterized.
