New fluorescent polymeric nanocomposites synthesized by antimony dodecyl-mercaptide thermolysis in polymer

Polymer – Coated Ferrite Nanocomposites Synthesized by Plasma Polymerization

Magnetic nanocomposites are an important class of advanced functional materials on the basis of a magnetic material and a matrix. To achieve unique mechanical, physical, chemical, and biomedical properties, one must be able to tailor only the surface structures of a nanoparticle. This requires the deposition of ultrathin and uniform films using the possibility offered by cold-plasma polymerisat...

New two in one magnetic fluorescent nanocomposites

Polymer-mediated growth of fluorescent semiconductor nanoparticles in preformed nanocomposites.

In this study, we investigated the size and photoluminescence (PL) evolution of CdTe nanoparticles (NPs) in different polymer media under thermal annealing. A quick growth and maintenance of strong PL were observed. By analyzing the transmission electron microscopy (TEM) images of NPs in polymer media, we discovered that the size evolution of NPs was the combination of Ostwald ripening and dyna...

Dynamics in Polymer Nanocomposites

Polymer diffusion and matrix morphology are investigated in polymer nanocomposites (PNCs). Using elastic recoil detection, tracer diffusion coefficients (D) of dPS and dPMMA are measured in PNCs containing polystyrene (PS) with phenyl-capped (Ph) silica, and poly(methyl methacrylate) (PMMA) with hydroxylterminated (OH) silica nanoparticles (NPs), respectively. As NP volume fraction increases or...

Polymeric nanocomposites: compounding and performance.

Polymeric nanocomposites (PNC) are binary mixtures of strongly interacting, inorganic platelets dispersed in a polymeric matrix. For full exfoliation, the thermodynamic miscibility is required. There are three basic methods of organically-modified clay dispersion that might result in PNC: (1) in polymer solution (followed by solvent removal), (2) in a monomer (followed by polymerization), and (...
