Abstract
The present invention relates to a carbon fiber-containing curable organosilicon composition and a method for preparing the carbon fiber-containing organosilicon composition. The present invention also relates to the electrically conductive rubber obtained by curing the carbon fiber-containing organosilicon composition and its uses. The curable organosilicon composition comprises: (A) a polysiloxane base composition, and (B) a carbon fiber component; wherein, the carbon fiber component comprises, based on the weight of (A) polysiloxane base composition, 2 to 300%, preferably 5 to 250%, more preferably 15 to 150% of a carbon fiber with average length of 10 μm to 5000 μm, preferably 30-3500 μm, more preferably 60-3000 μm with the provisos that: (1) if the carbon fiber component comprises exclusively carbon fiber with average length of not greater than 200 μm, its content is greater than 25%; and (2) if the carbon fiber component comprises exclusively carbon fiber with average length of greater than 2800 μm, its content is not greater than 40%.
