FUNCTIONALIZING PS MICROSPHERES BY SUPERCRITICAL DEPOSITION OFP(S-b-tBA) FOR DIVERSE INTERFACIAL PROPERTIES EXEMPLIFIED WITH BIOCIDAL ABILITY
Polystyrene (PS) microspheres were functionalized with poly(styrene-
b
-
tert
-butyl acrylate) (P(S-
b
-
t
BA)) by adsorption from supercritical mixture of CO
2
and hexane. Supercritical deposition formed a shell-core structure that contained a shell of poly(
tert
-butyl acrylate) (P
t
BA) blocks and a core of the PS blocks entangling with the PS microspheres. The thickness of the P
t
BA layer and thereby the areal density of
tert
-butyl ester groups increased with the deposition pressure until plateau values attained at 20 MPa and higher. The
tert
-butyl ester groups were hydrolyzed to carboxyl groups for conjugation with
tert
-butylamine molecules
via
amide bonds that were further chlorinated into biocidal
N
-halamine moieties. The functionalization layer and its bonded
N
-halamine moieties were stable in flowing water and the chlorine could be regenerated upon eventual loss. This functionalization concept is applicable to polymers of any external and internal surfaces to achieve diverse surface properties by varying block copolymer and conjugated moieties.
