The presentation will discuss recent works to manipulate the shape and function of soft materials for applications in functional surfaces, electronics and actuators. The research harnesses physical behavior of soft materials at surfaces and interfaces and unconventional surface patterning. The presentation will discuss three topics. First, complex nanopatterns in a form of hierarchically sequenced morphologies in block copolymer films on lithography-free topographic substrates are demonstrated. Second, gallium-based liquid metals at room temperature are patterned into microchannels of tough silicones to form ultra-stretchable wires and microelectrodes. Shape-memory polymeric materials with electrical conductivity are demonstrated by patterning the liquid metals and switching the phase of the metals. Third, a facile approach to achieve localized and hierarchically structured surfaces by buckling instability on a metal/polymer bilayer is presented. |
