Area of Science:

  • Materials Science
  • Biomaterials Engineering
  • Chemical Engineering

Background:

  • Gellan gum systems are versatile, with potential in cultural heritage for paper artwork cleaning.
  • Stable microgels enhance gellan gum's cleaning efficacy, especially when functionalized (e.g., methacrylated) for hydrophobic residue removal.

Purpose of the Study:

  • To characterize the rheological properties of low-acyl gellan gum hydrogels and microgels during formation.
  • To assess the influence of temperature, concentration, methacrylation, cations (Na+, Ca2+), and salt concentration on rheological behavior.

Main Methods:

  • Rheological characterization (viscosity, viscoelastic moduli) of gellan gum gels.
  • Systematic variation of parameters including temperature, gellan concentration, and ionic environment.

Main Results:

  • Gellan hydrogels and microgels exhibit a distinct double yielding behavior under conditions optimal for art restoration.
  • Identified optimal rheological conditions for efficient artwork restoration using these gellan gum systems.

Conclusions:

  • The study provides a thorough understanding of gellan gum gel rheology for art restoration applications.
  • Optimal rheological conditions pave the way for broader applications in substrate cleaning and other fields.
