PU nanoibers were subjected to argon plasma to generate oxide and peroxide groups on
the surface. It was then immersed in 4-vinylpyridine monomeric solution with exposure
to UV radiation, to graft poly(4-vinylpyridine) on PU ibers. The potential of polycarbonate
(PC)/chloroform solution with quaternary ammonium salt (benzyl tri-ethylammonium
chloride, BTEAC) as antimicrobial nanoibrous membranes was explored by Kim et al.

The addition of BTEAC to PC inhibited the growth of
S. aureus
,
E. coli
, and
Klebsiella pneu-
monia
. This iltration showed 99.97% iltration eficiency of 0.3-μm particles.
