Evaporating Polymer Produces Webby Patterns
Controlling the evaporation of a drop of diblock copolymer under just the right conditions leads to self-assembly of weblike macrostructures, report Suck Won Hong, Jun Wang, and Zhiqun Lin of Iowa State University (Angew. Chem. Int. Ed., DOI: 10.1002/anie.200903552). The ordered structures could be useful in preparing multifunctional materials for optoelectronic devices or as platforms to study cell adhesion and motility. The researchers dissolved the asymmetric diblock copolymer polystyrene-b-poly(methylmethacrylate) in toluene . . .
