Title: COMPOSITE BODY HAVING COATING LAYER OF CERAMIC CRYSTAL, AND METHOD FOR PRODUCING SAME
Abstract:
Provided is a composite body in which ceramic crystals are thinly and uniformly coated onto a base material containing a hydrophilic polymer. The composite body includes: the base material which includes a hydrophilic polymer; and a ceramic layer coating at least a part of the surface of the base layer. The ceramic layer contains crystals having a laminated structure. The ceramic layer may contain calcium phosphate. The thickness of the ceramic layer is 0.3-50 nm. The composite body is produced through a step for mixing and then stirring the following: a dispersion in which the base material is dispersed; a first solution containing calcium ions; and a second solution containing phosphate ions.
