Preparation of Silicone Rubber SR Nanocomposites

The following methods have invariably been used in the preparation of silicone rubber nanocomposites. [Pg.89]

In this method, a calculated amount of filler is first swollen within the liquid monomer and the polymerization is initiated by heat/radiation in presence of a suitable initiator. Large varieties of silicone rubber nanocomposites have been prepared by this method [122]. [Pg.89]

In this method, a solvent is chosen as a reaction medium in which the polymer (or pre-polymer) is soluble and the nanofillers are also well dispersed. Such polymer/prepolymer and dispersed filler are vigorously intermixed by mechanical stirring/ultrasonic vibration at a desired temperature followed by the evaporation of the solvent. A large number of silicone rubber nanocomposites have been prepared by this method, i.e., silicone foams filled with carbon nanotubes [123-127], graphite nanosheets/sfiicone rubber [128-130], graphene sheets/SR [131], MMT/SR [132], POSS/PDMS nanocomposite [133], LDH/SR [134,135].
