23 Jul Preparation method of magnetically induced self-repair nanometer composite hydrogel
Abstract
The invention discloses a preparation method of a magnetically induced self-repair nanometer composite hydrogel. A nanocomposite material with a metal nano-material grows on the surface of magnetic nanometer particles is used as a cross-linking agent, and the hydrogel employs magnetic nanometer particles which produce heat that drives precious metal-sulfur coordination bond to dynamically vibratein an alternating magnetic field as a healing main body; furtherly, the precious metal nanoparticles flourishingly grow on the surface of magnetic nanometer particles by an electrostatic action, the structure is novel, many crosslinking positions are provided, and accordingly, the hydrogel has dense crosslinking network and high stretching stress-strain; the magnetic nanometer particles can respond in the magnetic field and induce self-healing, and the product has good application prospects in the fields of anti-fatigue materials, biological medicines, tissue engineering and the like.
