essentially maintains contact of the polymers at their interface"
(Specification ¶¶ 13 and 16).
[11] The specification does not define the claim term "monolithic."
[12] Table 1 is said to show data for composites of carbon aerogel and (a)
phenolic resin foam, (b) resorcinol resin foam and (c) furan foam
(Specification 6:1).
[13] Table 1 does not show any porosity data for the three carbon aerosol-
foam composites which are said to have densities of (a) 125, (b) 124
and (c) 115 kg/m3, respectively (Specification 6, Table 1).
B. Droege
[14] Droege describes a method of forming an aerogel/carbon substrate
composite comprising infusing a porous carbon substrate with a
mixture of carbon aerogel precurors, allowing the infused porous
carbon substrate to form a gel/porous substrate composite, curing the
gel/porous substrate composite, drying the cured gel/carbon substrate
composite and pyrolyzing the dried gel/carbon substrate composite
(Droege col. 2, ll. 15-20; col. 7, ll. 18-20; col. 14, ll. 15-65).
[15] The carbon aerogel precursors comprise an aqueous solution of
resorcinol ("R"), formaldehyde and a sodium carbonate catalyst ("C")
having a molar concentration R/C value of greater than about 1000
(Droege col. 4, ll. 24-30; col. 5, ll. 1-5; col. 6, l. 65 - col. 7, l. 5; col.
14, ll. 25-31).
[16] The porous carbon substrate may take a variety of forms, including
fibers and reticulated foams (Droege col. 14, ll. 49-65).
