Forty years after their discovery, triblock or star copolymers of PS and polyisoprene (PI) or PB, denoted SIS and SBS, still dominate the market for block copolymers and their blends. They are ...

These different regions of a block copolymer chain are like oil and water ... both expensive (upwards of $2.50 per gram) and require multi-stage processing involving carefully controlled extrusion ...

What is Block Copolymer Lithography? Block copolymer lithography is a nanofabrication technique that utilizes the self-assembly properties of block copolymers to create ordered nanostructures. Block ...
