Hybrid nanocomposites based on crystalline nanoparticles dispersed in polymer matrix has been widely studied in the past few years because of the ability of these materials to combine both properties of organic polymer and inorganic nanoparticles. The aim of this work is to tune mechanical properties of piezoelectric polymer by adding nanoparticles to the matrix. In this paper alumina nanoparticles...
Nanocomposites were prepared from organoclay and aramid obtained from 4-aminophenylsulfone and isophthaloyl chloride in dimethylacetamide. Thin hybrid films were characterized by transmission electron microscopy, X-ray diffraction, tensile testing, thermogravimetric analysis, differential scanning calorimetry and water absorption measurements. Improvements in tensile modulus (122%), mechanical strength...
In order to improve the sound damping effect of a flexible polyurethane foam with an open-cell structure, various kinds of plate-like fillers, such as bentonite, organophilic clay, sodium montmorillonite intercalated with poly(ethylene glycol), were incorporated to create nanocomposites. The plate-like fillers effectively improved the sound damping in the high frequency range. The structures of the...
