| 摘要 |
The present invention relates to a method of enhancing hydrophilicity of a hydrophobic polymer material, comprising: pre-treating the hydrophobic polymer material, comprising treating the hydrophobic polymer material with a first atmospheric pressure plasma discharge in a first atmosphere comprising carbon dioxide to obtain a pre-treated polymer material, and treating the pre-treated polymer material with a second atmospheric pressure plasma discharge in a second atmosphere in which an aerosol of an amine is introduced, said amine comprising at least one hydrocarbon substituent. A substrate is provided as well, the substrate comprising a hydrophobic polymer material having a modified interface, wherein the modified interface comprises amine functional groups grafted on the hydrophobic polymer material, the modified interface having a surface energy, which, measured after immersion in water at 20°C for 3 days, differs from a surface energy of the hydrophobic polymer material by 20 mN/m or less. |
