摘要: Abstract Hydrophobically modified chitosan was prepared using the hydrophobic compound derived from natural resource material such as cashew nut shell liquid. Chitosan 3-pentadecyl cyclohexane carbaldehyde to different extents (2, 3, and 5 mol%). Solution properties of hydrophobically were studied by rheology light scattering. These indicated aggregation behavior above critical association concentration. Further, it concluded that concentration, dynamics network formed due associations slowed down significantly.
