| Abstract: |
| The dynamic interfacial shear viscosity of NP-4, sodium oleate and montmorillonite was measured using SVRS interfacial rheometer. With the time delay, the interfacial shear viscosity of NP-4 and sodium oleate under certain concentration decreases while the interfacial shear viscosity of montmorillonite increases before it reaches a fixed value. The results show that the dynamic phenomena of the film of different substances are distinctively different. |
| Key words: interfacial film dynamic interfacial shear viscosity NP-4 sodium oleate montmorillonite |
