Synthesis, Characterization and Properties of Organoclay-Modified Polysulfone/Epoxy Interpenetrating Polymer Network Nanocomposites

Recent advances in the preparation of functionalized polysulfones

“…134 In another study, the hydroxyl telechelic polysulfones were mixed with diglycidyl ether of bisphenol A type epoxy resin and organo-modified montmorillonite nanoclays to obtain hybrid nanocomposites. 135 Various reactive groups, aliphatic hydroxyethyl, 136 phthalic anhydride, 137 -139 (meth)acrylates 140 -144 and benzoxazine 145,146 groups, were also introduced to hydroxy end-functionalized polysulfones by addition of ethylene carbonate, 4-fluorophthalic anhydride, (meth)acryloyl chlorides and aniline/paraformaldehyde. The resulting telechelics were used as crosslinkers, chain extenders and important building blocks for various macromolecular structures, including block and graft copolymers and hybrid networks.…”

“…The hydroxy‐terminated polysulfones were also converted to (4 R )‐hydroxy‐ l ‐proline‐terminated polysulfones by following a three‐step synthesis: alkylation of hydroxyl groups with 12‐bromo‐1‐dodecanol; substitution of the new resulting hydroxyl groups by chlorine; and final substitution of chlorine atoms by (4 R )‐hydroxy‐ l ‐proline . In another study, the hydroxyl telechelic polysulfones were mixed with diglycidyl ether of bisphenol A type epoxy resin and organo‐modified montmorillonite nanoclays to obtain hybrid nanocomposites . Various reactive groups, aliphatic hydroxyethyl, phthalic anhydride, (meth)acrylates and benzoxazine groups, were also introduced to hydroxy end‐functionalized polysulfones by addition of ethylene carbonate, 4‐fluorophthalic anhydride, (meth)acryloyl chlorides and aniline/paraformaldehyde.…”

Clay-Containing Polysulfone Nanocomposites

“…Another nanocomposite, composed of polysulfone and epoxy, with a montmorillonite organomodified with cetyltrimethylammonium bromide was produced by solution dispersion. Homogeneous exfoliated nanocomposites with very improved mechanical properties were obtained (Rajasekaran et al, 2008). Polysulfone nanocomposites were prepared by contacting a polymeric antimicrobial agent with clay (e.g.…”

Synthesis and characterization of polysulphone/clay membrane: effect of natural clay differences

“…Most of the work done on PSf/clay nano-composite membranes had focused on the mechanical and thermal stabilities, anti-corrosion, anti-microbial and barrier properties as well as application in fuel cells [8][9][10]. These membranes were also prepared using solution dispersion methods.…”
