Block copolymer self-assembly is a process where two or more different polymer segments, known as blocks, spontaneously organize themselves into well-defined structures at the nanoscale. This phenomenon occurs due to the selective interactions between the blocks, which leads to phase separation and the formation of unique morphologies such as micelles, vesicles, or thin films. This self-assembly technique is crucial in nanolithography for creating nanoscale patterns and structures with controlled features.
congrats on reading the definition of block copolymer self-assembly. now let's actually learn it.
