| titleOfInvention | A kind of preparation method of hydrophobically modified SiO2 grafted polyvinyl alcohol superhydrophobic fiber membrane |
| abstract | The invention relates to the technical field of super-hydrophobicity, and discloses a hydrophobically modified SiO 2 grafted polyvinyl alcohol super-hydrophobic fiber membrane. The surface hydroxyl groups of SiO 2 are reacted to convert into hydrophobic and lipophilic SiO 2 , and the polyvinyl alcohol It is esterified with mercaptoethylene to obtain polyvinyl alcohol containing a large number of mercapto groups, and then the hydrophobically modified SiO is grafted into the polyvinyl alcohol matrix through the mercapto - ene click reaction, so that the hydrophilic polyvinyl alcohol is transformed into As a hydrophobic material, nano-SiO 2 is introduced by grafting, which has very good dispersibility, so that a large number of micro-nano-structured protrusions and micro-porous structures are better formed on the surface of polyvinyl alcohol, so that when the droplets are in contact with water , the micropores below close the air to form an air cushion, so that the composite fiber membrane has a bionic super-hydrophobic structure similar to that of lotus leaves, which increases the contact angle between water and the polyvinyl alcohol fiber membrane, giving the polyvinyl alcohol material a super-hydrophobic structure. Hydrophobic properties. |
