NanotechnologyNanotechnology

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 ScaleWhy 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.

ResultsResults

Nano ZnO was successfully surface modified by PEG and PPG

The adsorption has done by hydrogen bondPEG, contained compound has shown faster

curing system and better Improving the properties like abrasion,

tensile strength, modules 100%, modules 300% and elongation
