Abstract
A shape memory polymer article is disclosed. The article may include a surface having a microstructure and it may include a shape memory polymer. The shape memory polymer may include a copolymer network. The copolymer network may be formed from the reaction product of a free radically polymerizable siloxane having greater than one functional free radically polymerizable group and at least one (meth)acrylate monomer.
