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.
Why Properties Changein 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.
Nanomaterials Used in Rubber Field • Nano activator (ZnO) • Nano filler (CNT, Nano Silica, Nano Clay)
Problems consequent using nano ZnO Small size Agglomeration Hydrophyl surface
Surface modification Electrostatic stabilization Steric stabilization
Results • Nano ZnO was successfully surface modified by PEG and PPG • The adsorption has done by hydrogen bond • PEG, contained compound has shown faster curing system and better • Improving the properties like abrasion, tensile strength, modules 100%, modules 300% and elongation
