Abstract
Thermally treated aerogel compositions that include polyamic amides in an amount less than the aerogel compositions that include polyamic amides prior to thermal treatment, and articles of manufacture that include or are manufactured from the aerogel compositions are described.
Claims23
A method of making, a thermally treated polyamic amide aerogel, the method comprising:
- (a) providing at least one diamine compound to a solvent to form a solution;
- (b) providing at least one dianhydride compound to the solution of step (a) under conditions sufficient to form a polyamic acid solution;
- (c) providing a secondary amine to the polyamic acid solution;
- (d) subjecting the solution of step (c) to conditions suitable to produce a polymer matrix solution comprising a polyamic amide;
- (e) subjecting the polymer matrix solution to conditions sufficient to form an aerogel comprising an open-cell structured polymer matrix having a polyamic amide;
- and
- thermally treating the (e) polyamic amide aerogel at a temperature sufficient to lower the amount of the polyamic amide in the aerogel.
