Biocompatible film with variable cross-sectional properties |
摘要 |
A biocompatible film includes a single layer having a plurality of components, at least one of the plurality of components having a predetermined non-uniform distribution in the thickness direction of the single layer. The at least one of the plurality of components that has a non-uniform distribution in the thickness direction of the single layer may have a substantially uniform distribution in the longitudinal and lateral directions of the single layer. The biocompatible film can be made by depositing a fluid composition including a film forming material and at least one other component immiscible with the film forming material and having a density different than the film forming material into a single layer, and drying the single layer such that the at least one other component has a predetermined non-uniform distribution in the thickness direction of the single layer after drying.
