To employ block \ncopolymers in many applications, it is essential to understand how interfacial energetics \ninfluence copolymer morphologies.  Two areas of recent research in the group involve: \n(1) probing the effects of interfacial composition on block copolymer self-assembly \nusing tapered block copolymers, and (2) generating gradient substrate and \u201cfree\u201d \nsurfaces for thin films block copolymer studies.  In the first area, we are manipulating \nthe interfacial region between blocks to control ordering transitions in tapered diblock \ncopolymers and triblock copolymers.  This ability to adjust copolymer energetics allows \nus to generate nanoscale networks for applications ranging from analytical separation \nmembranes to ion-conducting materials.  In the second area, we are manipulating \npolymer thin film interfacial interactions using discrete gradient methods to control the \nfree surface interactions, and gradient arrays of assembled monolayers to influence the \nsubstrate surface interactions.  In particular, our chlorosilane monolayer gradients and \nsolvent vapor gradients permit rapid screening of the surface\/polymer interactions \nnecessary to induce the desired nanostructure orientations in many block copolymer \nsystems.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EIn addition to its annual lectures, ChBE\nhosts a weekly seminar throughout the year with invited lecturers who are\nprominent in their fields.
