Abstract
The present invention relates to a monolithic multi-layered material having at least a first layer, from which anisotropic pores originate, and a second layer, in which the anisotropic pores continue. The present invention further relates to a monolithic medical material having at least a first layer, from which anisotropic pores originate, and a second layer, in which the anisotropic pores continue. The present invention further relates to a process for the production of a multi-layered material having anisotropic pores. It further relates to a multi-layered material which can be produced by the process according to the invention.
Claims49
A monolithic multi-layered material having at least a first layer, from which anisotropic pores originate, and a second layer, in which the anisotropic pores continue.
A monolithic medical material having at least a first layer, from which anisotropic pores originate, and a second layer, in which the anisotropic pores continue.
A process for the production of a multi-layered material having anisotropic pores, comprising the steps of
- (a) providing a temperature gradient between two temperature-controllable bodies arranged opposite one another;
- (b) arranging in the temperature gradient a first substance which contains at least one sublimable compound and solidifying the first substance to form a first layer;
- (c) arranging and solidifying in the temperature gradient a second substance which contains at least one sublimable compound adjacent to the first substance and solidifying the second substance to form a second layer adjacent to the first layer;
- (d) subliming the sublimable compounds of the adjacent first and second layers to form a monolithic support matrix of the first and second layers having pores generated by the subliming;
- and
- (e) consolidating the layers.
A medical material having at least two different layers, wherein pores extend anisotropically through at least two layers of the material.
