Hybrid Nanocomposites for Nanotechnology: Electronic, ...
Fu et al. [108] have shown the effect of bonding of POSS moieties to a polymer
chain. While POSS-POSS interactions dominate in physically blended systems
resulting in aggregation of POSS molecules, the POSS-polymer interaction is
more ...

Silicon-Containing Dendritic Polymers
Nevertheless, low yields are often obtained and so most work on POSS
molecules involves the synthesis of vinyl or hydrido-POSS and subsequent
reactions to attach a variety of functional groups. POSS molecules were first
isolated in 1946 ...

the cyclopentyl and cyclohexyl POSS copolymers are still >106 Pa. These moduli
are significantly higher than that of either polystyrene or the isobutyl POSS
copolymer. This illustrates how POSS units can markedly effect polymer

However, the incorporation of POSS in epoxy networks can lead to both increase
and decrease in Tg and elastic moduli, as well as to unchanged
thermomechanical properties. The POSS unit can act as a reinforcing nanofiller
or as a ...

The most common polyhedral structure is the cubic shaped POSS with formula
R8Si8012, even though other cages with well-defined geometries include n = 6,
10, 12, 14, 16 and 18 [4, 5]. Cubic POSS, therefore, is the focus of this research.

produced the more desired results in polycarbonate/POSS blends. [20] Chemical
modification of the peripheral groups present in POSS. and the effects of these
functionalizations upon composite performance is the focus of the current work.
