A unique kind of polymeric system known as a block copolymer (BCP) is one in which each of the polymer chains is made up of two or more chemically different homopolymer blocks that are covalently joined.
BCP-based materials are typically utilised in bulk form, while more recently thin films have seen an increase in utilisation.
Patterned BCP thin films are perfect for emerging nanotechnologies like microelectronics, magnetic storage, solar cells, optics, and acoustics because of their nanoscale property.
The exact control of structural orientation, local alignment, and long-range ordering is critical for technologies necessary to transfer structure created by the self-assembly of BCP thin films into patterning applications.
Block copolymers (BCPs) are macromolecules made up of two or more homopolymer blocks that are covalently joined together but have different chemical compositions.
Usually, dozens to hundreds of recurring chemically identical units make up a block. A variety of chain architectures, including linear, branching, cyclic, and hybrid molecular architectures, can be created by connecting different blocks in different topologies.
The capacity of BCP to spontaneously self-assemble into exquisitely organised nanostructures is one of their very useful qualities. Homopolymers that differ chemically typically oppose one another, resulting in phase separation.
The homopolymer building components in BCP, however, are covalently bound together. Therefore, in BCP melts, a microphase separation takes place as opposed to a microphase separation. In this review, we focus on the diblock copolymer’s most basic form, in which each linear chain is made up of two blocks, A and B.
The characteristic length scales of these clearly defined structural groupings range from a few nanometers to hundreds of nanometers.
One of the main reasons BCP materials can be a desirable substitute for patterning technology to create nanostructures and nanopatterns, which are made using traditional lithographic procedures similar to those used in the manufacture of microelectronics, is because of this.
The self-assembly of BCPs can extend beyond the characteristic length limits imposed by conventional device fabrication techniques, giving BCPs in nano-lithography an additional advantage.
This enables BCPs to meet the ongoing efforts to increase the speed of microprocessors and the storage density of hard disk drives.
The Global Block Copolymer Thin Films market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Block copolymers are perfect for developing nanotechnologies since they self-assemble on nanoscale length scales.
The utilisation of block copolymers in thin film geometries, where self-assembly is heavily impacted by surface energetics, is necessary for several applications (such as membranes and templating).
We discuss confinement, substrate surface modification, temperature and solvent annealing conditions, as well as the roles of surface and interfacial factors on self-assembly in this review.
The employment of gradient and high-throughput approaches to obtain a complete understanding of self-assembly in order to enable new nanotechnologies is motivated by our last remarks on revolutionary thin film manipulation and characterization techniques.
For their prospective applications, block copolymers (BCPs), which are made of different polymer blocks linked by covalent bonds, are of great interest.
This is especially true for BCP thin films, which may be affordably produced using solution processing techniques on a wide range of substrates.
Different domains with adjustable dimensions and functionality can form from the diverse blocks. A number of variables, including the interaction of the BCP molecules with the substrate, the film thickness, and the post-deposition annealing methods, might affect the degree of long-range order and orientation of these domains.
Coil-coil diblock copolymers, in which each block is a fully flexible polymer chain, have been the subject of the majority of studies on BCPs. These BCPs produce well-understood structures.
