Claim Text:
1. A method of forming a loudspeaker cone comprising: (a) contacting in a liquid medium a modified carbon nanotube that includes a first binding moiety with at least one of a paper-forming compound and a paper-treatment compound having functional additives and control additives in a manner effective to retain the modified carbon nanotube to the one of the paper-forming compound and the paper-treatment compound to form a first adduct, the paper-forming and the paper-treatment compound together forming a paper compound; and (b) forming the loudspeaker cone by; (i) removing the liquid medium from the paper compound and the first adduct; and (ii) reacting the first adduct with the paper compound in a manner effective to chemically bind the modified carbon nanotube to the paper compound; (iii) where the step of forming the loudspeaker includes forming a filter mass containing the paper compound, the first adduct and residual liquid medium, and the step of reacting the first adduct includes heating the filter mass in a manner effective to substantially remove the residual liquid medium and cure the first adduct with at least one of the control additives, functional additives and the paper forming compound.
