Electrical and thermomechanical properties of epoxy-POSS nanocomposites

Two types of the epoxy-POSS nanocomposites were prepared and their electrical-epoxyfunctionalized POSS (POSS,E1 and POSS,E8) were covalently incorporated in the epoxy units or as polyhedral junctions, respectively....

Effect of POSS on thermomechanical properties of epoxy?POSS nanocomposites

The epoxy?POSS hybrid networks with POSS bound as pendant cages or with untethered POSS dispersed in the matrix were prepared and their structure was controlled of the hybrids with tethered POSS. The complex effect...

Structure ordering and reinforcement in POSS containing hybrids

The rubbery Epoxy?POSS (polyhedral oligomeric silsesquioxane) hybrid networks have been prepared by incorporating the novel diepoxy?POSS monomer in an epoxy network. During the hybrid network formation, monitored in situ by SAXS, th...

Polymer nanocomposites with bound inorganic nanobuilding blocks. Structure, formation and mechanical properties

POSS-POSS interactions, resulting in POSS crystallization, are crucial for the structure and mechanical properties of the POSS-containing nanocomposites. Crystalline domains of the pendant POSSs serve as physical c...

Formation of nanostructured epoxy networks containing polyhedral oligomeric silsesquioxane (POSS) blocks

silsesquioxanes (POSS), were investigated. The POSS were incorporated in the network as crosslinks oras pendant units by using octa- or monoepoxy-POSS monomers, respectively, as well as diepoxides with pendant POSS

Polyhedral oligomeric silsesquioxane (POSS)-based epoxy nanocomposite involving a reversible Diels–Alder-type network as a self-healing material

Epoxy-polyhedral oligomeric silsesquioxane (POSS) nanocomposites were prepared by incorporating POSS nanofiller into the epoxy-amine network. The monofunctional epoxy-POSS monomer or nonfunctional octaphenyl POSS u...

Nanostructured hybrid chitosan/POSS films in amino acid transport

The effect of POSS is manifested by the smaller fluxes of Ala and Trp through both protonated and deprotonated Chi/DL-POSS films, which could be associated with their higher density compared with Chi/OA-POSS and Chi/TMA-

Epoxy networks reinforced with polyhedral oligomeric silsesquioxanes (POSS). Thermomechanical properties

In this paper thermomechanical properties of the POSS-reinforced epoxy networks are determined and discussed. The paper explains the reinforcing effect of POSS and the relationships between structure and mechanical properties of the...

Polyurethane nanocomposites containing the chemically active inorganic Sn-POSS cages

the heavier, tin-based homologues of POSS (“Sn-POSS”). Most remarkable was the tremendous effect of extremely small Sn-POSS concentrations (around 0.05 wt%) on the glass transition (up-shift by 30–60 °C) of the oxidized Sn...
