Modified porous materials and method of forming the same
First Claim
1. A method of modifying porous materials having interconnected, complexly shaped three-dimensional surfaces, the method comprising the step of:
- pretreating the porous materials with an ethanol solution or a surface charge modifying agent; and
stabilizing the pretreated porous materials by directly coating the three-dimensional surfaces with a layer of gelatin;
wherein the porous materials are macro structures including at least one of nano-features, micro-features, and combinations thereof, and wherein the porous materials are substantially stable in a predetermined environment.

Abstract
Modified porous materials are disclosed having interconnected, complexly shaped three-dimensional surfaces. The modification is accomplished by crosslinking the three-dimensional surfaces and/or by coating the three-dimensional surfaces with a layer of a predetermined material. The porous materials are macro structures including at least one of nano-features, micro-features, and combinations thereof. The modifying accomplishes changing surface properties of the porous materials, changing the three-dimensional surfaces, and/or rendering the porous materials substantially stable in a predetermined environment.
