Characterization of Nanosilica/Low-Density Polyethylene Nanocomposite Materials

Near-Field Optical Characterization of Nanocomposite Materials

*We present a near-field optical technique *-hich makes use of the strongly enhanced optical field at a laser-illuminated metal tip. The enhanced field is used to locally excite the sample under investigation by multiphoton absorption. An optical scan image w-ith spatial resolutions dow-n to 20 nm is established by detecting the emitted fluorescence. The principle of the method is described and...

Characterization of Nanocomposite Materials: An Overview

Experimental Study for Dielectric Strength of New Nanocomposite Polyethylene Industrial Materials

The base polymer properties have been developed experimentally by adding small amounts of different fillers but they are expensive to the polymer material. Thus, it has been investigated that the incorporation of cost-less nanoparticles like clay and fumed silica nanoparticles into low density polyethylene LDPE and high density polyethylene HDPE which controlled the breakdown strength and volta...

Preparation and Characterization of Layered Silicate Polyethylene Terephthalate Nanocomposite by in Situ Polymerization

A series of experiments on the synthesis of poly (ethylene terephthalate) (PET)/organo-montmorillonite (MMT) nanocomposites were carried out in a pressurized reactor using alkyl ammonium exchanged smectite clays, (Closite 30B).Given the degradation of organoclay at high temperatures, the in situ polymerization process was carried out at mild temperatures ranging from 210 to 230°C for 40 minutes...

Biological Evaluation of the Copper/Low-density Polyethylene Nanocomposite Intrauterine Device

Devices and materials intended for clinical applications as medical and implant devices should be evaluated to determine their biocompatibility in physiological systems. This article presents results from cytotoxicity assay of L929 mouse fibroblasts culture, tests for skin irritation, intracutaneous reactivity and sensitization, and material implantation tests for the novel copper/low-density p...
