The Effect of Clay and Al2o3 on the Properties of Up Nanocomposites: Unsaturated Polyester Nanocomposites with Layer and Spherical Nanofiller

?NANO TECHNOLOGY?and producing the different form of matter in scale of ?NANO?, in recent decade, are the subject of very interesting research. ?NANO COMPOSIT? as a branch of ?NANO TECHNOLOGY? are very important and are the fields of active researches. Polymer nanocomposites have attracted great interest, both in industry and in academics, because they exhibit remarkable improvement in material properties compared with virgin polymer. In present book the ?NONE SATURATED POLYSTER are particularly discussed. Among the thermoset materials, unsaturated polyester resins shows special chemical characteristics such as curing over a wide temperature range and the control of degree of cross-linking. ?NANO PARTICLES? which are used in present different sample ?NANO COMPOSITES? sentenced are Cloisite®30B and AL2O3 and composed them. UP/NANOFILER nanocomposites were investigated by X-ray diffraction , SEM and TEM. Sentence and mechanical specialty of each kind of clay are particularly explained. To investigate the formation these UP nanocomposites, dynamic mechanical thermal analysis were performed.
