| Popis: | Nanoparticles coated with poly(octadecyl acrylate) (POA) pour-point depressants are investigated, and the effect of the amount of coating material is investigated and compared with the effect of the coating material without nanomaterial. Pour point depressing performance is demonstrated using a model waxy oil system in order to isolate material performance. The present study focus on the effect of how the amount of coverage of the nanoparticles affects the performance of the nanoparticles. In order to access this information, the adsorption of the poly(octadecyl acrylate) (POA) on silica (the material of the nanoparticles) was determined using a quartz crystal microbalance with dissipation monitoring (QCM-D). Adsorption was performed from two different solvents, toluene and dodecane, because the nanoparticles were been prepared from toluene while the model system used is dodecane-based. Using the QCM-D data, it was possible to prepare nanoparticles with different amounts of poly(octadecyl acrylate), as de... |
