Appeal 2007-1938 Application 10/050,437 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). 5Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Next
