  • Is chitosan a functionalized or graft copolymer?
  • Functionalized and graft copolymers of chitosan and its pharmaceutical applications Chitosan is the second most abundant natural polysaccharide. It belongs a family of polycationic polymers comprised of repetitive units of glucosamine and N-acetylglucosamine.
  • How chitosan based flocculant should be characterized?
  • Each chitosan-based flocculant should be characterized the physical and chemical properties (e.g., DD, crystallinity, and polymer weight etc.), since the characteristics can greatly affect its viscosity and solubility and further affect the harvesting capacity for microalgae in culture medium.
  • What happens when chitosan backbones are heated?
  • The heating initiates a transformation from H-bonding aggregates to a large-sized cluster formed by self-assembled hydrophobic chitosan backbones.
