Polyimide nanofiber aerogel with hierarchical porosity: a novel platform in high-temperature oil absorption
Abstract
The
development
of
advanced
oil
sorbents
with
superior
thermal
stability,
high
adsorption
capacity,
and
excellent
reusability
is
crucial
for
addressing
hot

challenges,
particularly
in
the
petrochemical
machinery
industries.
This
study
presents
a
novel
polyimide
(PI)
nanofiber
aerogel
(PIF-a)
designed
high-temperature
absorption.
Utilizing
electrospinning
post-treatment,
PIF-a
exhibits
hierarchical

remarkable
flexibility.
At

Despite
repeated
adsorption-desorption
cycles,
PIF-a's
remains

retaining
over
90%
