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.
Claims28
A thermally treated aerogel comprising an open-cell structured polymer matrix that includes a polyamic amide polymer and a polyamic amide containing co-polymer, wherein the polyamic amide containing co-polymer comprises two repeating structural units of:
- where:
- X is a first organic group having at least two carbon atoms;
- Y is a second organic group having at least two carbon atoms;
- Z and Z′ are each independently a hydroxyl group or a nitrogen containing hydrocarbon compound comprising at least one secondary nitrogen with the proviso that that at least one of Z or Z′ is the nitrogen containing hydrocarbon compound comprising at least one secondary nitrogen, and
- m and n are average number of repeat units per chain ranging from 1 to 2000.
