Abstract

Methods, apparatuses, and systems for fabricating porous materials using thixotropic gels. A shear force is applied to a thixotropic material causing the material to flow. Multiple components are added to the thixotropic material while applying the shear force causing the multiple components to be distributed in the material. The shear force is removed such that the static properties of the thixotropic material in the absence of the shear force retain a distribution of the multiple components in the thixotropic material to form a composite gel material that includes liquid within a network of inter-connected solid particles that include the distributed plurality of components. The liquid in the composite gel material is removed to form a porous composite material.
