Investigation of Mechanical Properties of PMMA-modified α-Alumina / Polymethylmethacrylate Nanocomposite

Polymethylmethacrylate can be used in many applications, but due to its rigidity in some cases does not have sufficient strength. Recently nanotechnology has been used for improving of the nanocomposites properties. Different reinforcements were used for the preparation of polymethylmethacrylatenanocomposites which graphene oxide is one of them[1].The main problem in the using of nano-materials is related to the lack of proper dispersion in the polymer matrix. Modified nanomaterials can overcome this problem partially. In this research, the modified graphene oxide was prepared by insitu polymerization in the presence of methy methacrylate as monomer and used for this purpose [2]. Poly methyl methacrylate nano composite was prepared by Melting method [3]. FT-IR, TGA and DSC techniques were applied in order to characterization of prepared nano composites. To investigate of the mechanical properties of nano composites stretching, bending and impact tests were carried out.
