| titleOfInvention | A kind of preparation method of long-acting super-hydrophobic copper-based material |
| abstract | The invention discloses a kind of preparation methods of long-acting super-hydrophobic copper-based material, it aoxidizes including copper powder after cleaning only with silver nitrate and is then modified by lauryl mercaptan, it is again 150 ° by suppressing building to obtain contact angle, the copper substrate superhydrophobic surface that roll angle is 5 °, copper powder is first cleaned, then copper powder is aoxidized using Na OH/ (NH4) 2S2O8 and silver nitrate, it is handled afterwards by the ethanol solution of lauryl mercaptan, when the concentration of Na OH/ (NH4) 2S2O8 is respectively 0.76 mol/L/0.24 mol/L, silver nitrate concentration is 0.03 mol/L, lauryl mercaptan concentration is 0.15 mol/L, soaking time is 24 h, contact angle has been obtained when pressure is 150 MPa is 153.2 °, roll angle be 7 ° of super-hydrophobic copper-based material.The preparation method of the long-acting super-hydrophobic copper-based material is because it is with good immersion stability.In addition, we drip the acid-base solution of different p H on super-hydrophobic sample prepared by two schemes, it is found that the copper-based material of the two schemes preparation when p H is 3-14 can still keep good hydrophobic performance. |
