1 Application of Surface Modified Nano Zinc- Oxide in Sulfur Vulcanization of Tire Tread Compound I- Azad University, North Tehran Branch IRAN Rubber Industries Engineering and Research Institute Dr. Saeed Taghvaei Mercedeh Malekzadeh Dr. Saeed Taghvaei Mercedeh Malekzadeh

2 Contents  Nanotechnology  More common nanomaterials used in rubber field  Problems consequent using Nano ZnO in rubber matrix  Surface modification of Nano ZnO  Application of surface modified Nano ZnO in tire tread compound  Results

3 Nanotechnology Nanotechnology is a broad field of applied science and technology focused on controlling and exploiting the structure of matter on a scale below 100 nanometers.

4 Why Properties Change in Nano Scale  Increased ratio of surface area to volume present in many nanoscale materials opens new possibilities in surface-based science.  Quantum effects impacting behavior of materials.

5 Nanomaterials Used in Rubber Field  Nano activator (ZnO)  Nano filler (CNT, Nano Silica, Nano Clay)

6 Small size Problems consequent using nano ZnO Hydrophyl surface Agglomeration

7 Steric stabilization Surface modification Electrostatic stabilization

8 Nano Particles Characterization
