Area of Science:

  • Materials Science
  • Biomaterials Engineering
  • Polymer Chemistry

Background:

  • Chitin, a natural polymer, offers unique functionalities for self-assembling complex materials.
  • Challenges in chitin-based composite assembly arise from poor solubility and compatibility.
  • Developing advanced chitin composites requires strategies to overcome these limitations.

Purpose of the Study:

  • To develop a novel strategy for enhancing chitin-based composite hydrogel performance.
  • To improve the compatibility between chitin and inorganic materials using quercetin.
  • To create robust and functional chitin-based composite hydrogels.

Main Methods:

  • A quercetin-mediated multiple crosslinking strategy was employed.
  • Quercetin was utilized to mediate interfacial interactions between chitin and inorganic fillers.
  • Non-covalent interactions were modulated to enhance hydrogel toughness and filler dispersion.

Main Results:

  • Achieved high-performance chitin-based composite hydrogels with toughness ranging from 0.70-1.02 MJ·m⁻³.
  • Demonstrated effective dispersion of various inorganic materials (molybdenum disulfide, carbon nanotube, calcium carbonate) within the hydrogels.
  • Quercetin-mediated interactions enhanced energy dissipation through sacrificial non-covalent bonds.

Conclusions:

  • The quercetin-mediated strategy effectively enhances chitin compatibility and hydrogel performance.
  • This approach enables the creation of diverse chitin-based composites with tunable functionalities.
  • The developed strategy offers a promising pathway for advanced biomaterial development.
