    Abstract: A method of producing silicone foam includes the step of adding a mechanical foaming agent to uncured silicone. The mechanical foaming agent is a plurality of solid bodies insoluble in the silicone. The method also includes the steps of curing the silicone and removing the mechanical foaming agent as intact solid bodies from the silicone thereby providing a silicone foam.

    Abstract: A composition has a polymeric network that includes a porogen and a photoinitiator. The photoinitiator produces a reactive species upon irradiation, which reacts with the porogen in a degradation reaction that degrades at least some of the porogen. A method of forming a nanoporous polymer has one step in which a plurality of polymeric strands, a photoinitiator, and a porogen are provided. In a subsequent step, at least some of the polymeric strands are crosslinked to form a polymeric network that includes the porogen and the photoinitiator, and in a further step the photoinitiator in the polymeric network is irradiated to generate a reactive species that reacts with the porogen in a degradation reaction to degrade at least some of the porogen.
