8.20 POLYSULFONE
Dow Corning Z-6106 is suggested as an effective adhesion promoter for polysulfone.
Lignocellulose nanofibrils and cellulose nanofibrils are popular nanometer additives
to improve mechanical properties and hydrophilic abilities (lignocellulose is a natural
1
adhesion promoter in fiber-reinforced composites) of polysulfone. They were blended
into polysulfone to prepare ultrafiltration membranes via the phase inversion method. Fig-
1
ure 8.8 shows the mechanisms of adhesion improvement by lignocellulose.
The thermoplastic composite material includes polysulfone aromatic polymer com-
2
bined with an adhesion promoter. The polysulfone aromatic polymer is a polysulfone aro-
matic polymer, a polyethersulfone aromatic polymer, or a polyphenylsulfone aromatic
2
polymer. The adhesion promoter is a polyamideimide or a polyamide-amic acid poly-
2
mer.
