| 内容記述 | Chitosan is a polysaccharide extracted from Crustacea. Chitosan sol is produced by dissolving chitosan in a solution of organic acids. Chitosan film can be fabricated from chitosan sol, which has been neutralized with 5% polyphosphate solution and gelatinized. Chitosan film is characterized by both its elasticity and in vivo absorbtion capacity. Although the chitosan film become inelastic when dried, they will return to an elastic state when soaked in water. It is of practical importance to determine the amount of calcium ions dissolved from the hydroxyapatite which is kneaded with the chitosan film. In the present study, the relationship of various amounts of added hydroxyapatite and chitosan to shrinkage, hardness, tensile strength and elongation of the chitosan film was determined in addition to the amount of dissolved calcium ions. The following results were obtained. The shrinkage during drying was decreased by increaseing the amount of hydroxyapatite added. The hardness showed a maximum value at the ratio of hydroxyapatite: chitosan sol= 4 : 11. The hardness was increased by increasing the amount of chitosan. The tensile strength of the chitosan films kneaded with hydroxyapatite exhibited a higher value than those without haydroxyapatite. Elongation showed the highest value when the ratio of hydroxyapatite:chitosan sol=2 : 11. The tensile strength and elongation were increased by incresing the amount of chitosan. The amount of calcium ion dissolution showed the highest value when the ratio of hydroxyapatite:chitosan sol=4 : 11. When chitosan film was soaked in physiological saline, the original level of elasticity was restored. | |||||||
