Properties of Shengli Crude Oil
  1. Size and size distribution of PAA core dispersed in hexane.
  2. Size variation of PAA core and PAA-PVK brush along with storing time.
  3. Size distribution of PAA core and PAA-PVK brush redispersed in different organic media.
  4. Optical micrographs and particle size analysis of model oil (a, b) and crude oil (c, d) emulsions in water with the presence of PAA core.
  5. Size distribution of water soluble PS-PSS brushes.
  6. Optical images of crude oil-in-water emulsions formed by oil soluble PAA-PVK brushes and water soluble PS-PAA brushes.
  7. Apparent viscosity of crude oil under different temperatures.
