Self-assembled polymer nanocomposites and their networks

Self-assembled lamellar MoS2, SnS2 and SiO2 semiconducting polymer nanocomposites.

Lamellar nanocomposites based on semiconducting polymers incorporated into layered inorganic matrices are prepared by the co-assembly of organic and inorganic precursors. Semiconducting polymer-incorporated silica is prepared by introducing the semiconducting polymers into a tetrahydrofuran (THF)/water homogeneous sol solution containing silica precursor species and a surface-active agent. Semi...

Conducting, Self-Assembled, Nacre-Mimetic Polymer/Clay Nanocomposites.

UNLABELLED We demonstrate electrically and ionically conducting nacre-mimetic nanocomposites prepared using self-assembly of synthetic nanoclay in combination with PEDOT PSS and a poly(ionic liquid) polymer from aqueous dispersions. The resulting nacre-mimetics show high degrees of mesoscale order and combine high stiffness and high strength. In terms of conductivities, the resulting hybrids ...

Anisotropic structure and transport in self-assembled layered polymer-clay nanocomposites.

Using the layer-by-layer (LbL) assembly technique, we create a polymer-clay structure from a unique combination of LbL materials: poly(ethylene imine), Laponite clay, and poly(ethylene oxide). This trilayer LbL structure is assembled using a combination of hydrogen bonding and electrostatic interactions. The films were characterized using ellipsometry, profilometry, X-ray photon spectroscopy, a...

Colossal Dielectric and Electromechanical Responses in Self Assembled Polymeric Nanocomposites

Preparation and Characterization of Chitin Nanowhiskers and their Polymer Nanocomposites

C is the second most important natural polymer in the nature after cellulose. The main sources of the chitin compounds are shrimp and crabs.Our objective is to discuss the state of the art on extraction of nano chitin whiskers and Chitin based nanocomposites using different type of polymer matrixes. This review manly focuses on the preparation, characterization, properties, morphologies and che...
