Abstract
Official abstract text for this publication.
In one embodiment, a method includes acquiring a three-dimensional printed template created using an additive manufacturing technique, infilling the template with an aerogel precursor solution, allowing formation of a sol-gel, and converting the sol-gel to an aerogel. In another embodiment, a product includes an aerogel having inner channels corresponding to outer walls of a three-dimensional printed template around which the aerogel was formed.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method, comprising: acquiring a three-dimensional printed template created using an additive manufacturing technique; infilling the template with an aerogel precursor solution; allowing formation of a sol-gel; and converting the sol-gel to an aerogel. 2 . The method of claim 1 , comprising removing the template. 3 . The method of claim 2 , wherein the template is removed by pyrolization. 4 . The method of claim 2 , wherein the template is removed by application of a solvent thereto. 5 . The method of claim 2 , wherein the aerogel has defined regions with different densities upon removal of the template therefrom. 6 . The method of claim 1 , wherein converting the sol-gel to the aerogel includes pyrollyzing the sol-gel. 7 . The method of claim 1 , wherein the template remains after conversion of the sol-gel to the aerogel. 8 . The method of claim 1 , wherein the aerogel is carbonaceous. 9 . The method of claim 1 , wherein the aerogel includes a metal oxide. 10 . The method of claim 1 , wherein the template is created using a photo-activated resist. 11 . The method of claim 1 , comprising creating the template. 12 . A product, comprising: an aerogel having inner channels corresponding to outer walls of a three-dimensional printed template around which the aerogel was formed. 13 . The product of claim 12 , wherein the template is not present in the product. 14 . The product of claim 12 , wherein the template is present in the product. 15 . The product of claim 12 , wherein the aerogel is carbonaceous. 16 . The product of claim 12 , wherein the aerogel includes a metal oxide. 17 . The product of claim 12 , wherein the aerogel has distinct regions with different densities. 18 . The product of claim 12 , wherein the template is created using a photo-activated resist. 19 . The product of claim 12 , wherein at least some of the channels have straight longitudinal axes of at least 1 micron in length. 20 . The product of claim 12 , wherein the aerogel is spatially non-uniform.
