An electrically conductive composition comprises a polymeric foam and carbon nanotubes. The composition has a volume resistivity of about 10<-3 >ohm-cm to about 10<8 >ohm-cm. In another embodiment, an electrically conductive elastomeric composition comprises an elastomer and carbon nanotubes, and has a volume resistivity of about 10<-3 >ohm-cm to about 10<3 >ohm-cm. The polymeric foams and elastomers retain their desirable physical properties, such as compressibility, flexibility and compression set resistance. They are of particular use as that articles provide electromagnetic shielding and/or electrostatic dissipation, especially for applications involving complicated geometries, such as in computers, personal digital assistants, cell phones, medical diagnostics, and other wireless digital devices, electronic goods such as cassette and digital versatile disk players, as well as in automobiles, ships and aircraft, and the like, where high strength to weight ratios are desirable. |
