| titleOfInvention | PH-responsive plant fiber functional material and preparation method and application thereof |
| abstract | The invention discloses a pH responsive plant fiber functional material and a preparation method and application thereof, wherein plant fiber is used as a matrix, and a negative pH responsive group and a positive pH responsive group are grafted on the surface of the plant fiber through free radical initiation; by controlling the concentrations of the negative pH response monomer and the positive pH response monomer in a reaction system to be respectively maintained at 0.138-0.552 mol/L and 0.14-0.56 mol/L and controlling the addition sequence of the monomers, the mass ratio of the negative pH response group to the positive pH response group grafted on the surface of the plant fiber is 1: 2-4 or 2-4: 1, and the total grafting rate of the groups on the surface of the plant fiber is 50-80%, so that the material has high pH response sensitivity in a narrow pH range, the bidirectional intelligent conversion between the hydrophilic and oleophobic properties and the oleophilic and hydrophobic properties of the material is realized, and the material has high oil-water separation efficiency, good regeneration stability and good environment applicability. |
