Poly(acrylic acid) provides a means of tailoring the electrical conductivity and mechanical behavior of an aerogel by altering pH during processing. The aerogel shown here, prepared from a pH 3 aqueous mixture containing 2.5 wt.-% PAA, 5 wt.-% clay, and 0.05 wt.-% SWNT, has a compressive modulus of 462 kPa and conductivity of 1.67 × 10−6 S · cm−1.
