Mesoscale self-assembly in block copolymer has excited interest for many applications. However, the practical realization is limited because of the inability to control the self-assembly. Thus we need to develop a facile method to precisely control the orientation and long range order of the nanoscale structure. The focus is on vertical alignment of self-assembled lamellar and cylindrical microdomains in block copolymer films. This has application in nanoporous membranes used in chemoselective transport and size-selective separations.

Microdomains are known to assemble spontaneously in vertical arrangement under the influence of surface forces in block copolymer films thinner than 1 um.

Mesoscale self-assembly in block copolymer has excited interest for many applications. However, the practical realization is limited because of the inability to control the self-assembly. Thus we need to develop a facile method to precisely control the orientation and long range order of the nanoscale structure.
