Inverting the design path for self-assembled block copolymers

Recent success of inverse design methodologies in the realm of self-assembled materials has allowed us to envision an inverse path of discovery where we go from a desired target function to building blocks.

Beyond native block copolymer morphologies

Block copolymers self-assemble into a range of canonical morphologies. Here, we review a broad range of techniques for inducing these materials to form structures beyond the ‘native’ morphologies seen in the bulk equilibrium phase diagram. Methods that exploit intrinsic encoding (molecular design) and external enforcement (directed assembly) are compared.

Nanolithography of cylinder forming block copolymers via DSA for semiconductor manufacturing

To realize the full benefit of directed self-assembly (DSA), it is necessary to understand the interplay between the target structures and the process parameters.

Cooperative effects of inorganic and organic structure-directing agents in ZSM-5 crystallization

A combination of bulk crystallization studies and molecular modelling are used to elucidate the role of dual inorganic/organic SDAs in ZSM-5 synthesis. Our findings reveal unexpected synergistic effects on crystallization times and physicochemical properties.

Spatially-controllable and uniform photochemical transfer printing of block copolymer nanopatterns

This work describes the use of a bilayer conformal layer strategy to transfer print the chemical nanopatterns from one substrate to another, enabling the successful directed self-assembly of block copolymer thin films with 1 : 1 microdomain registration.

Directing block copolymer self-assembly with permanent magnets: photopatterning microdomain alignment and generating oriented nanopores

Phase behavior and dynamics of a LC block copolymer are manipulated by labile mesogens to enable alignment, photopatterning and nanopore orientation at low magnetic fields.

Electric field directed self-assembly of block copolymers for rapid formation of large-area complex nanopatterns

We investigate the unusually rapid directed self-assembly of block copolymer (BCP) thin films by imposing an in-plane electric field.

About this collection

From MSDE

Guest Edited by Professor Paul Nealey and Dr Mark Stoykovich at the Institute of Molecular Engineering at the University of Chicago, USA.

This collection aims to highlight recent progress in the field of directed self-assembly, with a special emphasis on the use of templates, external fields, and/or control of molecular-level interactions to induce self-assembling materials such as polymers, liquid crystals, and nanoparticles to organize with precise two- or three- dimensional nanostructure.  We want to emphasize, where possible, how the structure resulting from directed-self-assembly (not self-assembly) of the materials system imparts specific properties, function, or organization over device-relevant length scales that enable specialized applications.
