| Abstract: | The surface properties of plastic column packing and its wetting conditions were discussed. The main methods to improve surface wetting property of plastic column packing were pointed out that surface molecular structure was changed for increasing polarity and surface was coarsened for raising surface tension. And the surface modified methods, such as surface coarsening, surface polarization, surface graft and surface treatment of plasma were introduced. |
