Abstract:
1. A method for depositing a conformal coating on a porous non-ceramic substrate, comprising: providing a reactor having an inlet and an outlet; positioning at least a portion of at least one porous non-ceramic substrate such that the porous non-ceramic substrate separates the inlet from the outlet; performing at least one iteration of sequentially introducing a first and a second reactive gas at the inlet such that the first and second reactive gases flow through the porous non-ceramic substrate to the outlet so as to conduct a sequence of two or more self-limiting reactions at the interior surfaces of the porous non-ceramic substrate to form a conformal coating on at least a portion of the interior surfaces; and wherein the performing step is iterated until a surface energy of the interior surfaces is 72 dynes/cm or greater and the exterior surface of the porous non-ceramic substrate nearest the outlet has a surface energy less than 72 dynes/cm.
