|Title:||Well Ordered Polymer Melts from Blends of Disordered Triblock Copolymer Surfactants and Functional Homopolymers|
|Published:||April 04, 2008|
|Abstract:||Here, we report that well ordered, processible polymer melts with periodic nanostructures can be obtained in bulk quantity by simple blending of commercially available triblock copolymer surfactants with a series of commodity homopolymers that selectively associate with one of blocks through hydrogen bonding. While the neat surfactants are disordered in the melt, scattering measurements indicate that the blends undergo a disorder-to-order transition to yield stable microphase separated structures. The results are general, and suggest a low cost, high volume strategy to produce ordered spherical, cylindrical, or lamellar microphase separated polymer melts for commercial use.|
