This paper deals with organic clays used as nano fillers and their potential usage in the cable industry together with traditional inorganic flame retardants for cable compounds. The main attention is targeted on their fire retardant effect. Further an approach to the effect on material properties induced by the nanometric scale of fillers is given. Their electrical, mechanical and processing properties...
This chapter describes composite materials composed of dendrimers and metals or semiconductors. Three types of dendrimer/metal-ion composites are discussed: dendrimers containing structural metal ions, nonstructural exterior metal ions, and nonstructural interior metal ions. Nonstructural interior metal ions can be reduced to yield dendrimer-encapsulated metal and semiconductor nanoparticles. These...
Nanostructured organic-inorganic composites have been the source of much attention in both academicand industrial research in recent years. Composite materials, by definition, result from the combinationof two distinctly dissimilar materials, the overall behavior determined not only by properties ofthe individual components, but by the degree of dispersion and interfacial properties. It is termeda ...
A substantial amount of work has been carried out in the area of dielectric nanocomposite materials. However, reported nanocomposite materials generally have disadvantages such as high dielectric loss mainly due to the nanoparticle agglomeration. Here, we present a novel nanocomposite material having polyvinylpyrrolidone (PVP) functionalized gold nanoparticles (5 nm in diameter) embedded inside a...
Polysaccharides such as cellulose, starch, and chitin are abundant, natural, renewable, and biodegradable polymers produced by nature. Because of the naturally occurring multiscale structure of these polymers consisting of alternating crystalline and amorphous domains, their controlled acid hydrolysis treatment disrupts this organization and releases crystalline particles with nanoscale dimensions...
A novel nanocomposite material was designed and synthesized for potential use in energy storage devices. It comprises of gold nanoparticles of diameter 5nm and SU-8 polymer. Scanning Electron Microscopy, Transmission Electron Microscopy and Energy Dispersive X-ray Spectroscopy techniques were used for the characterization of the nanocomposite material. The presented work represents a major first step...
In this research, novel nanocomposite scaffolds with compositions based on cross-linked gelatin (Gel) and bioactive glass (BaG) nanoparticles in the ternary SiO2-CaO-P2O5 system were prepared and fully characterized. The scanning electron microscopy (SEM) observations revealed that the prepared scaffolds were porous with three dimensional (3D) and interconnected microstructure, pore size was 200-500...
The deposition of needle-shaped cuprous oxide (Cu2O) particles (20~50 nm) on chitosan nanoparticles were made by anodic oxidation of copper electrode in alkaline solution, Fe2+ was immobilized by chitosan nanoparticles with chelating. Chitosan-Fe2+/Cu2O were used as an immobilized Fenton reagent activated by visible light at biocompatible pH values(pH≈7-8) in the degradation of brilliant red X-3B...
