Molecular structure of bottlebrush polymers in melts
Bottlebrushes are fascinating macromolecules that display an intriguing combination of molecular and particulate features having vital implications in both living and synthetic systems, such as cartilage and ultrasoft elastomers. However, the progress in practical applications is impeded by the lack of knowledge about the hierarchic organization of both individual bottlebrushes and their assemb...
متن کاملThermoresponsive PNIPAAM bottlebrush polymers with tailored side-chain length and end-group structure.
We explore the phase behaviour, solution conformation, and interfacial properties of bottlebrush polymers with side-chains comprised of poly(N-isopropylacrylamide) (PNIPAAM), a thermally responsive polymer that exhibits a lower critical solution temperature (LCST) in water. PNIPAAM bottlebrush polymers with controlled side-chain length and side-chain end-group structure are prepared using a "gr...
متن کاملBright Fluorescent Nanotags from Bottlebrush Polymers with DNA-Tipped Bristles.
Bright signal outputs are needed for fluorescence detection of biomolecules at their native expression levels. Increasing the number of labels on a probe often results in crowding-induced self-quenching of chromophores, and maintaining the function of the targeting moiety (e.g., an antibody) is a concern. Here we demonstrate a simple method to accommodate thousands of fluorescent dye molecules ...
متن کاملDiagram of States of Bottlebrush Polymers under Poor Solvent Conditions
Introduction Bottlebrush polymers are macromolecules which consist of a long chain serving as “backbone” onto which flexible side chains are densely grafted. There is a lot of recent interest in both the synthesis of these macromolecules and characterization of physical properties by various experimental techniques (light and neutron scattering, atomic force microscopy, electron microscopy, etc...
متن کاملMicrophase separation in bottlebrush polymers under poor-solvent conditions
Molecular-dynamics simulations are used to study the structure of bottlebrush polymers with rigid backbones, for various grafting densities, side chain lengths, and varying solvent quality. While we confirm different states of the bottlebrush proposed by Sheiko et al. (Eur. Phys. J. E, 13 (2004) 125) we find that the transition between stretched and collapsed brushes occurs in a rather gradual ...
