Nanocomposites of colloidal semiconductor nanocrystals integrated into conjugated polymers are the key to soft-material hybrid optoelectronics, combining advantages of both plastics and particles. Synergic combination of the favorable properties in the hybrids of colloidal nanocrystals and conjugated polymers offers enhanced performance and new functionalities in light-generation and light-harv...

In this work, the impacts of varying surface modification, matrix parameters, and fabrication conditions on the performance of optically printed (0-3) piezoelectric polymer nanocomposites are examined. For example, we find that a 75% reduction in nanoparticle edge-length boosted the piezoelectric coefficient (d33) by over 100%. By optimizing the composition and fabrication conditions, 10% by ma...

New organic electronic organic ammonia sensors based on hybrid nanocomposites polyaniline-titanium dioxide and on PANI/chitosan with high metrological performances were created. The physical and chemical properties of the nanocomposites were optimized to get a high sensitivity and very low detection threshold (in ppb values). For hybrids, in the core shell form, the performances were analyzed b...

This paper reviews the mechanism of the conducting process of carbon nanotubes (CNTs)-reinforced polymer nanocomposites. Comparison of the two different mechanisms, the formation of the conducting network and the hopping of the electrons, are discussed. The paper also describes the critical factors that determine percolation thresholds or the conductivity of the nanocomposites. By summarizing t...

In this study, PMAs/NiFe2O4 nanocomposite was prepared using in-situ polymerization technique. The structure and morphological properties of nano composited were determined via FT-IR, SEM, EDX analysis methods. Thermal properties of prepared nanocomposites were investigated by TGA, DTA and DSC. Pure NiFe2O4 nanoparticles were synthesized using hydrothermal synthesis using the same conditions wi...

Many attempts have been made to fabricate various types of inorganic nanoparticle-filled polymers (filler/polymer nanocomposites) by a mechanical or chemical approach. However, these approaches require modification of the nanofiller surfaces and/or complicated polymerization reactions, making them unsuitable for industrial-scale production of the nanocomposites. The author and coworkers have pr...

The fields of the nanocomposites and membranes have received a lot of attention and close examination of scientists and engineers in recent years. This makes it possible to design and create new materials with unprecedented flexibility. The driving force behind the fabrication of novel nanocomposites is to achieve high functional properties for high-end applications. This review provides an ove...

High temperature superconducting (SC) nanocomposites based on SC ceramics and various polymeric binders were prepared. Regardless of the size of the ceramics’ grains, the increase of their amount leads to an increase of resistance to rupture and modulus and a decrease in limiting deformation, whereas an increase in the average ceramic grain size worsens resistance properties. The SC, thermo-che...
