Abstract:
Nano science plays an important role in modern technology. This motivates trying to study the change of some electrical properties due to the change of Nano size structure. The aim of this work is to see how change of nano size of matter leads to a change in its electric permitivity. To do this, the research methodology is based on experimental work, in which nine samples of nacl were grinded for nine different grinding times, which are 10,20,30,40,50,60,70,80,90 minutes. The electric permitivity of these samples were measured by using a capacitor. The result shows that the electric permittivity decrease as the nano size decrease. This may be attributed to the fact that decreasing nano size increases density which decreases electric permitivity.
