H. Sawada et al., Synthesis and surface properties of novel fluoroalkyl end-capped amphiphilic fullerene cooligomers, POLYMER, 43(3), 2002, pp. 1035-1038
New fluoroalkyl end-capped fullerene cooligomers were prepared by the react
ions of fluoroalkanoyl peroxides with fullerene and comonomers such as acry
loylmorpholine, NN-dimethylacrylamide and acrylic acid. These fluorinated f
ullerene cooligomers were easily soluble in water and common organic solven
ts, and were able to reduce the surface tensions of both water and benzene,
quite effectively. Additionally, these fullerene cooligomers were found to
form a stable monomolecular film at the air-water interface, and the modif
ied polystyrene surface treated with these cooligomers was shown to have a
strong hydrophilicity with good oil repellency. (C) 2001 Elsevier Science L
