Abstract
The solubility of chitosan depended on its morphology mainly when its chemical structure was fixed. In viewing of this, we intended to modulate the water-solubility through tuning its morphology. Both the entanglement and crystalline degrees of chitosan could be varied through a common dissolution and precipitation processes, which resulted in the change of the water-solubility of chotosan accordingly. Several possible morphology models were presented for various samples obtained by simply changing the amount of solvents and precipitants. As a result, chitosan was able to be dissolved in water in absence of acid.
