Document Type and Number:
WIPO Patent Application WO/2015/125789
Kind Code:
A1
Abstract:
[Problem] To provide an inner face modified tube to which a surface modification treatment was implemented on the inner face of the tube in order to add prescribed functionality and which can exhibit sufficiently the added functionality and maintain the functionality over a long period. [Solution] An inner face modified tube (100) has particles (120) embedded in the inner face of a tube (110) in a state of partial exposure, wherein: the particles (120) are more unevenly distributed, on the basis of the thickness direction of the tube (110), in an area (A2) from the center (C) of the tube (110) toward the inner face of the tube (110) than in an area (A1) from the center (C) of the tube (110) toward the outer face of the tube (110); the material constituting the particles (120) is a material that does not bond covalently or ionically with the material constituting the inner face of the tube (110); the mean roughness (Ra) of the inner face of the tube (110) is no less than 1 nm and no more than 100 μm; the particle diameter of the particles (120) is no less than 10 nm and no more than 100 μm; and the inner diameter of the tube (110) is no less than 0.01 mm and no more than 100 mm.
