Carbon nanotube represent one of the best novel nanostructures which have different individual structures,morphologies and properties, a wide variety of synthetic methods have been developed to produce it and the properties for specific scientific studies or technological applications. Carbon Nanotube are one of the allotropes of carbon which can be described as a sheet of graphite rolled into a hollow cylinder constructed from hexagonal rings of carbon with diameters ranging from one to tens of nanometers, and with lengths up to micrometer.

Five transition metal complexes of Ni(II), Cu(II), Zn(II), Cd(II) and Sn(II) with {4-amino-5-(pyridyl)-4H-1,2,4-triazole-3-thiol}, as a ligand (L) has been prepared in alcoholic medium.The photostabilization activity of these compounds was determined by monitoring the carbonyl and hydroxylindexes, weight loss method with irradiation time. It was found that these indexes values increased with irradiation time and this increase depend on the type of additives. The surface morphology for these films was studied during irradiation time. The changes in viscosity average molecular weight of PS with...
