| We recently reported that cross links can be incorporated into surface-initiated polymer films which have been patterned by well-known soft lithographic methods. Objects can thus be created with lateral dimensions of the order of tens of microns but thicknesses of the order of tens of nanometres. Such films are mechanically robust enough to be separated from the substrate while maintaining their structural integrity; this can be achieved by, for example, electrical reduction of the bond between the polymer and the substrate, or under-etching of the substrate from below the film. We here discuss the relation between the cross linker incorporated into the films and their resulting physical properties. We also examine attempts to make such films responsive to external stimuli by the incorporation of suitable monomers into the surface-initiated polymer. |
