Bottlebrush polymers are a type of branched or graft polymer with polymeric side-chains attached to a linear backbone, and the unusual architecture of bottlebrushes provides a number of unique and potentially useful properties. These include a high entanglement molecular weight, enabling rapid self-assembly of bottlebrush block copolymers into large domain structures, the self-assembly of bottlebrush block copolymer micelles in a selective solvent even at very low dilutions, and the functionalization of bottlebrush side-chains for recognition, imaging, or drug 2 delivery in aqueous environments. This review article focuses on recent developments in the field of bottlebrush polymers with an emphasis on applications of bottlebrush copolymers.Bottlebrush copolymers contain two (or more) different types of polymeric side-chains. Recent work has explored the diverse properties and functions of bottlebrush polymers and copolymers in solutions, films, and melts, and applications explored include photonic materials, bottlebrush films for lithographic patterning, drug delivery, and tumor detection and imaging. We provide a brief introduction to bottlebrush synthesis and physical properties and then discuss work related to: i) bottlebrush self-assembly in melts and bulk thin films, ii) bottlebrushes for photonics and lithography, iii) bottlebrushes for small molecule encapsulation and delivery in solution, and iv) bottlebrush micelles and assemblies in solution. We briefly discuss three potential areas for future research, including developing a more quantitative model of bottlebrush self-assembly in the bulk, studying the properties of bottlebrushes at interfaces, and investigating the solution assembly of bottlebrush copolymers.

“…The particular interest lies in brushes with side-chain block copolymers [2,3], since they can lead to cylindrical "core-shell" structures. The range of potential applications of molecular brushes is extremely wide and covers molecular containers, nanowires, impact materials, elastomers, adhesives, stabilizers, dispersing agents, emulsifiers, compatibilizers, and materials for mineralization of inorganic crystals [4][5][6][7][8][9].…”

Comb-like polymethylsiloxanes consisting of a silsesquioxane backbone and dimethylsiloxane side chains were synthesized by means of the "grafting to" method using a linear polyfunctional matrix [SiMe(ONa)O] n and monofunctional oligomers (CH 3 ) 3 Si[OSi(CH 3 ) 2 ] n OCOCH 3 . The effects of architecture of the synthesized methylsiloxane polymers on their physicochemical properties, rheology, and behavior at the air-water interface were studied and compared with those for the linear analoguepolydimethylsiloxane.

“…When we now compare the results of our investigation into grafted comb-polymers and the results of investigations of combpolymers in solution, [19][20][21][22] there are clear similarities. In both cases the backbone will be more strongly stretched than it would have been without the side-chains, as its stretching reduces the polymer density for the side-chains.…”

Modeling the Structure and Antifouling Properties of a Polymer Brush of Grafted Comb-Polymers

et al. 2011

Numerical self-consistent field theory is used to study the structural characteristics of a polymer brush consisting of end-grafted comb-polymers. A comb-polymer brush is shown to retain the parabolic density profile characteristic of the unbranched brush. Increasing either the number of branches or the length of the side-chains leads to an increase in the height (H) of the brush. This is partly because of the branched structure: it is more favorable to stretch the polymer backbone, while leaving the side-chains almost unstretched. The other reason for the increased stretching is simply because of the extra polymer in the brush due to the branches. We find that it does not matter how the side-chains are distributed along the backbone for the predicted density profile; it is only the total amount of polymer in the side-chains that is important. The effect of branching on the brush height can be captured in a simple scaling law: H ∼ N b(N T/N b)2/3, where N b is the chain length of the polymer backbone, N T is the total chain length, thus including the side-chains, and their ratio N T/N b is a measure for the amount of branching. The structure of the branched brush is less suitable for keeping away small particles from the grafted interface. It is, however, a good way of increasing the polymer density, and thus its antifouling properties, when the grafting density of the brush is limited.
