Morphology of Silicone Rubber SR Nanocomposites

Methylsilicone nanocomposites have been prepared by solution blending methods using three different types of hydroxyl-containing POSS (TriSilanolphenyl-POSS, TriSilanolIsobutyl-POSS and MonoSilanolIsobutyl-POSS) and one non-hydroxyl-containing POSS (Methacryl-POSS). It is noted that aggregation tendency is more pronounced 

Keshojuefa/. [168] used nickel nanowires as a one-dimensional fiber to prepare the corresponding PDMS nanocomposites. Though nickel nanowires (0.42 wt%) are web dispersed in PDMS without agglomeration, the surface of pubed out nanowires is covered with 100 run thick polymer sheath. The PDMS nanocomposites of 6 wt% polyphosphazene nanotubes (/= 3-5 pm, d=100 run) also show that the fiber is web dispersed in the polymer matrix [169]. 

The nanocomposites of silicone foams containing 0.25 wt% functionalized graphene sheets (FGS) have been prepared by solution mixing [42,174]. It is established that the nature of the dispersion of the FGS is both exfoliated and intercalated.
