WebApr 12, 2013 · Re: Conversion of Weight Percent to a Volume Fraction *seriously impressed you got lattice parameter information from this mix!* After all that, the calculation you did in post 3 looks fine. Your 49% is the volume fraction of polymer though, your volume fraction of water is therefore 51%. 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.
