An organic polymer aerogel that includes an organic polymer gel matrix and microstructures dispersed or embedded within the aerogel is disclosed. The aerogel can have an at least bimodal pore size distribution comprising a first peak of less than or equal to 65 nm and a second peak greater than or equal to 100 nm.

Organic polymer aerogels comprising microstructures

Aerogel filled polymeric composites, methods of making and uses thereof are described. A polymeric composite material can include a continuous polymeric matrix and a discontinuous phase that includes a plurality of polymeric aerogel particles dispersed within the continuous polymeric matrix.

Filled composites with decreased thermal conductivity, dielectric constant, and weight

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.

Thermally treated polyamic amide aerogel

An aerogel that includes an open-cell structured polymer matrix is disclosed. The aerogel includes 5 wt. % to 50 wt. % of a polyamic amide polymer, based on the total weight of the aerogel, pores and at least 90% of the pore volume of the aerogel is made up of macropores, a porosity of at least 50%, as measure according to ASTM D4404-10, a density of 0.01 g/cmto 0.5 g/cm, and the aerogel is thermally stable to resist browning at 330° C.

Polymer aerogel with improved mechanical and thermal properties

A macroporous-structured polymeric aerogel, and methods for making and using the same, having a polymeric matrix that includes macropores is disclosed.

Macroporous-structured polymer aerogels

An aerogel that includes an open-cell structured polymer matrix that can have 5 wt. % to 50 wt. % of a polyamic amide polymer, based on the total weight of the aerogel is disclosed. The aerogel can have a density of 0.05 g/cmto 0.35 g/cmand can be thermally stable to resist browning at 330&#xb0; C.

Organic polymer aerogels, articles of manufacture, and uses thereof are described. The aerogels include an organic polymer matrix and microstructures dispersed within the aerogels, which provides for superior thermal conductivity and mechanical properties.

An aerogel comprising an open-cell structured polymer matrix that includes a polyamic amide polymer is described.

A method of making an aerogel is described. The method can include obtaining a solution comprising polyamic acid and an imidazole, adding a dehydrating agent to the solution in an amount where the molar ratio of the imidazole to the dehydrating agent is 0.17:1 to 2.8:1 and reacting the solution at room temperature to 100&#xb0; C. to produce a polymer matrix gel comprising a polyamic amide, and drying the polymer matrix gel to form an aerogel comprising an open-cell structured polymer matrix that includes 5 wt. % to 50 wt. % of the polyamic amide based on the total weight of the polymer aerogel.

Aerogel compositions that include polyamic amides, methods for preparing the aerogel compositions, and articles of manufacture that include or manufactured from the aerogel compositions are described.

A process used to cast films including; mixing Pyr-BBL and a room temperature molten salt from a range of about 35:65 weight ratio, dissolving the mixture in about 1% methanesulfonic acid to produce a Pyr-BBL solution, drop casting the solution onto glass or gold coated glass at 140&#xb0; C. in air and heating for about 2 hours to produce films, drying the films in a vacuum oven at about 100&#xb0; C. for at least 24 hours under dynamic vacuum, and rinsing the films to remove residual ionic liquid.
