WebThe data in the Table 5.9 show that a high packing volume can be obtained in real systems as compared with theoretical calculation results. A particle size decrease results in a decrease in the maximum volume packing fraction. A surface coating can increase the maximum volume packing fraction by reducing the thickness of the bound polymer. http://wwwcourses.sens.buffalo.edu/ce435/Koenig03.pdf
