| 摘要 |
<p>This invention relates to hydrophobic and oleophobic porous materials and processes for making the same. In a first process of the invention, a thermoplastic substrate is at least partially coated and/or impregnated with a surface treatment material. In a second process of the invention, thermoplastic particles which comprise a surface treatment material are sintered together. Preferred surface treatment materials are fluorochemicals.</p> |
