“…The samples were synthesised by the 'grafting from' approach in the group of Prof. Krzysztof Matyjaszewski (Carnegie Mellon University, USA). [260][261][262] The macromolecules were of different lengths of the main chain (DP of 3 700 and 400 for 'long' and 'short' molecules, respectively) and the side chains (DP of 30 and 60 for 'long' and 'short' molecules, respectively). All SFM experiments were performed by the author in the group of Prof. Martin Möller under his guidance using PicoSPM (Molecular Imaging, USA) device as described in our ref.…”

The modern state of SFM research on polymer nano-objects including single chains is discussed in comparison with other similar high-resolution microscopy techniques. The range of problems to be solved preferentially by SFM is highlighted. Promising methodology to describe quantitatively the morphology of macromolecular objects is proposed. The main benefits of this algorithm seem to be the apparent mathematical correctness as well as the possibility to estimate errors and the confidence of the numbers obtained. Special attention is paid to the dynamic observations of conformational transitions on a substrate in real time regime. This approach allows one to realise direct control of the adsorbed macromolecules by means of exposure to different vapours. Driving forces of the vapour-induced reorganisation are discussed.

“…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.

“…A previous study on similar brush-shaped copolymers crosslinked either covalently or physically resulted in elastomers with an unusually low equilibrium shear modulus G e , of order 1 kPa [1]. That behavior was attributed to the effect of the side chains on the brush polymers, which behave in some respect as a low molecular weight diluent that cannot be leached from the sample.…”
