New Macromolecular Research Findings from Ben-Gurion University of the Negev Described (Block Copolymer Ordering in Cylindrical Capacitors)

August 22, 2014



By a News Reporter-Staff News Editor at Science Letter -- Research findings on Macromolecular Research are discussed in a new report. According to news reporting from Beer Sheva, Israel, by NewsRx journalists, research stated, "We investigate the morphologies of block copolymers confined in the region between two concentric and charged cylinders."

The news correspondents obtained a quote from the research from the Ben-Gurion University of the Negev, "The relative stability of a concentric lamellar phase compared to one where the lamellae are oriented in the radial direction is determined from the competition between long-range elastic and electrostatic forces. We find in weak and strong segregation and by single-chain-in-mean-field simulations that under sufficiently strong voltage difference there is a phase transition from concentric to radial lamellae containing defects."

According to the news reporters, the research concluded: "Above a threshold voltage the block copolymer melt develops an interfacial instability at a finite wavelength."
