Direct 3-D Imaging of the Evolution of Block Copolymer Microstructures Using Laser Scanning Confocal Microscopy

摘要

Block copolymers(BCPs)exhibit various periodic structures created through microphase separation with tunable size and shape of microdomains via choice of molecular weight,composition,and chain architecture and with the addition of plasticizers or homopolymers.In order to tailor the desired properties of BCPs,it is critical to gain a fundamental understanding of the 3D structural details of these materials.
