Fabrication of functionally graded aerogels, cellular aerogels and anisotropic ceramics
Abstract
We report on the fabrication and characterization of anisotropic porous materials: functionally graded, cellular and compositionally anisotropic aerogels and ceramics. This new class of materials was fabricated by photopolymerizing selected regions of a homogeneous monolith using visible light. Visible light is not significantly absorbed and not significantly scattered by
