Double-Crystalline Block Copolymers on the Cover of Macromolecules
CBE graduate student Sheng Li and Professor Rick Register, studying materials synthesized by alumna Sasha Myers *08, have recently uncovered an unexpectedly broad range of nanoscale structures in polymers containing chemically dissimilar crystallizable blocks. Moreover, the structure can be tuned either through synthesis (total and block molecular weights), or through processing (such as crystallization during fiber drawing or quiescently). The latter aspect of this work was featured on the cover of the November 22 issue of the American Chemical Society’s journal Macromolecules, showing how the crystal orientation can be “flipped” through processing. For those with journal access, the full article is viewable here.
