- the tube was cut along a plane perpendicular to the length direction, and the thickness of the film was measured by observing the cross section with a scanning electron microscope. The result was 1.5 [zm].
- Obtained coaty Table 2 shows the evaluation results of the polyamide elastomer tube having the lining layer.
- Polyurethane prepolymers (C-2), (C-3), and (C-4) were prepared in the same manner as in Example 1 using the raw materials shown in Table 1. Next, in combination with the polyalcohol shown in Table 2, an elastomer tube having a urethane polymer layer was obtained in the same manner as in Example 1, and a hydrophilic polymer layer was formed. Table 2 shows the evaluation results of the obtained polyamide elastomer tube having the surface coating.
- a coating layer was formed on the surface in the same manner as in Example 1, except that the concentrations of the THF solution of the polyurethane prepolymer and polyalcohol during the formation of the urethane polymer layer were changed as shown in Table 2.
- Table 2 shows the evaluation results of the resulting polyamide elastomer tube with a surface coating.
- an elastomer tube having a urethane polymer layer was obtained in the same manner as in Example 2 except that the hydrophilic polymer material was changed to PEG4000, and then a hydrophilic polymer layer was formed.
- Table 2 shows the evaluation results of the obtained polyamide elastomer tube having a surface coating.
- a coating layer was formed on the surface of the substrate shown in Table 2 in the same manner as in Example 2.
- Table 2 shows the evaluation results of the obtained tube having the surface coating.
- a Pebax tube having a surface coating was obtained in the same manner as in the example except that the urethane polymer layer was formed at the ratio shown in Table 3. With the resulting surface coating Table 3 shows the evaluation results of the tubes.
- a urethane polymer layer was formed in the same manner as in Example except that glycols shown in Table 3 were used as the polyalcohol, and then a hydrophilic polymer layer was formed to obtain a tube having a surface coating.
- Table 3 shows the evaluation results of the obtained tube with the surface coating.
- a surface coating was formed in the same manner as in Example 2 except that the materials shown in Table 3 were used as the hydrophilic polymer material. Table 3 shows the evaluation results of the obtained tube with the surface coating.
- Example 1 13 exhibits excellent lubricity and durability when wet, and the surface has active hydrogen. It is clear that even a substrate having no functional group has excellent lubricity and durability.
- the surface coating of the present invention is a solid substrate that comes into contact with water, in particular, a blood bag, a urine collection bag, a blood transfusion set, a suture, a drain tube, various catheters, a blood access, a blood circuit, an artificial blood vessel, an artificial kidney, an artificial blood vessel.
- Suitable for medical devices such as cardiopulmonary, artificial valve, plasma exchange membrane, various adsorbents, CAPD, IABP, pacemaker, artificial joint, artificial bone head, dental material, intraocular lens, soft contact lens, and various shunts.
