摘要：

Nanohybrid systems are prepared from organogels of a partially fluorinated molecule and from thermoreversible gels of syndiotactic polystyrene. The thermodynamic behavior, morphology, and Structure are investigated by using differential scanning calorimetry, atomic forte microscopy, small-angle X-ray scattering (SAXS), and small-angle neutron scattering (SANS). The outcomes of these investigations suggest that the fibrils of the organogel coil around the sPS fibril, probably through a heterogeneous nucleation process. These systems therefore differ from previously investigated sPS/OPV Systems (oligo vinylene phenylene) where OPV fibrils pervade the sPS network.
