Preparation of Microcapsules Containing Erythritol with Interfacial Polycondensation Reaction by Using the (W/O) Emulsion

It was tried to microencapsulate erythritol as a phase change material with the interfacial polycondensation reaction method by using the (W/O) emulsion and to characterize the microcapsules prepared. In the experiment, toluene diisocyanate, diphenyl methane diisocyanate and hexamethylenediisocyanate were used to form the polyurethane shell and the effects of them on the heat storage density an...

Poly(p-phenylene Vinylene) Nanoparticles by Acyclic Diene Metathesis (admet) Polycondensation in Aqueous Emulsion

Chair of Chemical Materials Science, Department of Chemistry, University of Konstanz, Germany Introduction Poly(p-phenylene vinylene) (PPV) and its derivatives are amongst the most widely studied class of conjugated polymers since the discovery of their electroluminescent properties in 1990. These polymers are studied for applications in numerous photonic devices such as organic solar cells, or...

Synthesis and Characterization of Ag/PVP Nanocomposites by Reduction Method

A polyvinylpyrrolidone (PVP)/Ag nanocomposite was prepared by reduction of silver nitrate in ethylene-glycol in the presence of a polymeric protective agent (i.e., poly (N-vinylpyrrolidone)). The size dependent color variation of this nanocolloid is a clear indication of the presence of Ag as nanoparticles in the polymer matrix. The nonlinear optical properties were studied by Z-scan technique ...

Morphology and Melt Rheology of Nylon 11/Clay Nanocomposites

Nylon 11 (PA11)/clay nanocomposites have been prepared by melt-blending, followed by melt-extrusion through a capillary. Transmission electron microscopy shows that the exfoliated clay morphology is dominant for low nanofiller content, while the intercalated one is prevailing for high filler loading. Melt rheological properties of PA11 nanocomposites have been studied in both linear and nonline...
