A New Phase of Block Copolymers Discovered By Researchers


All matter consists of a number of phases—regions of the space with uniform construction and bodily properties. The common phases of H2O (liquid, solid, and gas), often known as ice, water, and steam, are well-known. Similarly, although much less acquainted, maybe, polymeric materials also can form different solid or liquid phases that determine their properties and ultimate utility. That is especially true of block copolymers, the self-assembling macromolecules created when a polymer chain of one type ("Block A") is chemically linked with that of a other type ("Block B").

"If you wish a block copolymer that has a certain property, you pick the right phrase for a given application of interest," defined Chris Bates, an assistant professor of supplies within the UC Santa Barbara College of Engineering. "For the rubber in shoes, you need one phase; to make a membrane, you need a different one."

Only about five phases have been discovered within the simplest block copolymers. Discovering a new section is rare, however Bates and a team of different UC Santa Barbara researchers together with professors Glenn Fredrickson (chemical engineering) and Craig Hawker (materials), Morgan Bates, workers scientist and assistant director for technology on the Dow Supplies Institute at UCSB, and postdoctoral researcher Joshua Lequieu, have done simply that.

Their findings are printed within the Proceedings of the National Academy of Sciences.

About a year ago, Morgan Bates was doing some experimental work on polymers she had synthesized within the lab, in an effort, she mentioned, "to know the fundamental parameters that govern self-assembly of block copolymers by examining what occurs when you tweak block chemistry."
