Abstract
A method for preparing a silicone elastomer porous material includes the steps of (1) providing a water-in-oil emulsion including a liquid silicone rubber material which forms a silicone elastomer upon curing, a silicone oil material that has a surface activation function, and water droplets dispersed in the liquid silicone rubber material, (2) subjecting the emulsion to a primary heating, thereby curing the liquid silicone rubber material to form a silicone elastomer and confining the water droplets within the silicone elastomer substantially as they are present in the emulsion, and (3) subjecting the silicone elastomer to a secondary heating, thereby evaporating and removing the water droplets from the silicone elastomer, thereby forming the silicone elastomer porous material.
