| titleOfInvention | Preparation method of stable segmented copolymer PAPMA (Polymethyl Acrylate P-acetamide Phenyl Ester)-b-PNIPAM (Polyisopropyl Acrylamide) based Au nanometer particle |
| abstract | The invention belongs to the technical field of chemical engineering and in particular relates to a preparation method of a stable segmented copolymer PAPMA (Polymethyl Acrylate P-acetamide Phenyl Ester)-b-PNIPAM (Polyisopropyl Acrylamide) based Au nanometer particle. The preparation method comprises the following steps of: synthesizing a macromolecular chain transfer agent PAPMA by adopting an RAFT (Reversible Addition-Fragmentation Transfer) method; synthesizing segmented copolymer PAPMA-b-PNIPAM by utilizing the macromolecular chain transfer agent PAPMA; and grafting the segmented copolymer PAPMA-b-PNIPAM to the surface of a gold nanometer particle to prepare the stable segmented copolymer PAPMA-b-PNIPAM based Au nanometer particle by using NaBH4 or hydrazine hydrate as a reducing agent of chloroauric acid and using the segmented copolymer PAPMA-b-PNIPAM as a high macromolecule stabilizer and reactant. According to the preparation method of the stable segmented copolymer PAPMA-b-PNIPAM based Au nanometer particle, the Au nanometer particle with good dispersion can be prepared by reacting under the room temperature through a one-step process. By utilizing the advantages including small dimension, large specific surface area and uniform grain size of the Au nanometer particle prepared by the preparation method disclosed by the invention, the stable segmented copolymer PAPMA-b-PNIPAM based Au nanometer particle can stably exist in a water solution for more than six months. |
