During the last decade, supramolecular chemistry (1) showed its great potential for the elaboration of innovative materials, with features such as self-healing or stimuli-responsiveness. Supramolecular materials are composed of polymer chains functionalized by strongly interacting moieties. These moieties, called “stickers”, can associate by non covalent interactions (hydrogen bonds, ionic…) and thus, form a transient network in the polymer matrix. While the self-assembly of stickers favors elastic behavior in the case of telechelic polymer chains (2), our group focused on the control of dissipative properties of center-functionalized polymers at small and large deformation (3), an important property for soft adhesives. The specificity of our project is to adjust the viscoelastic properties of non or lightly entangled center-functionalized polymers by varying the supramolecular parameters, such as the strength and the density of stickers. Monodisperse poly(butylacrylate) chains below and above their average molecular weight between entanglements, center-functionalized by multiple hydrogen bonding stickers were synthesized by ATRP. Their structure (by AFM and SAXS) and linear viscoelastic properties in the melt state were systematically characterized. Stickers are observed to self-assemble into cylindrical aggregates packed into a hexagonal structure. This supramolecular structure gives a gel-like character at low molecular weight and high sticker density while the entanglements’ dynamics makes them highly dissipative over a large frequency range (5 decades) for higher Mw and lower sticker density. The transition from one regime to another is easily adjusted by varying independently the length of the side chains and the nature of stickers. Such a fine control of the dissipative properties via chemical non random structures makes the supramolecular center-functionalized polymers promising to target fine-tuned innovative soft materials.
