“…These observations bear no hallmark of intrinsic ionic behaviour. They are, on the contrary, consistent with recent work that highlights the important role played in the transition by local interactions between anions and the amide groups in the PNIPAM chain [16,[44][45][46].…”

“…The broad peaks around 1300cm -1 represents the C-H and C-N in plane deformation. The characteristic PPy peaks are found in the lower wavelength region in which the peak at around 600cm -1 represents C-S stretching due to sulfonate doping [15]. In the CA doped composite the sharp peak appearing at 2352 cm -1 is due to carboxylic group in CA.…”

“…Indeed, in our group, we have prepared and modified various acrylamide-based block copolymers with CAs as pendant chains to study their effect on the tuning of the LCST. [45][46][47][48][49] Bile acids have the property of associating with ␤-cyclodextrin (␤-CD), due to the compatibility of the size and shape of bile acids with the cavity of ␤-CD. [50][51][52][53][54][55] This reversible association allows the tuning of the thermoresponsive properties via the addition of a supramolecular host.…”

Bile acids are gaining increasing importance as building blocks in the development of novel polymeric materials. This is evidenced by the growing number of publications advocating the advantages of their incorporation in the design and construction of materials. Composed of a rigid steroid backbone, functional groups with potential towards diverse reactions, and a biocompatible framework, there are various ways in which these molecules can be utilized to afford biomaterials via distinct architectures. Soft materials utilize the intrinsic capacity of bile acids to self-assemble and have seen a range of applications, most notably in the field of drug delivery. On the other hand, there is also the possibility of including bile acids in the polymer backbone, which has been used in the preparation of elastomers. This review discusses a selection of materials that can be prepared using bile acids and the advantages afforded by these molecules. Focus will be on the development of soft and hard materials, where soft materials are described as being held by weak intermolecular interactions, whereas hard materials are mechanically stronger with bile acids covalently incorporated in the polymer network.Key words: bile acids, polymers, biomaterials, drug delivery, dental composites. Résumé :Les acides biliaires sont des synthons de plus en plus importants dans la mise au point de nouveaux matériaux à base de polymères, comme en témoigne le nombre croissant de publications préconisant leur incorporation dans la conception et la fabrication de ces matériaux. Composées d'un squelette stéroïdien rigide, de groupes fonctionnels au potentiel réactionnel diversifié, et d'une structure biocompatible, ces molécules, de par leurs différentes architectures, présentent diverses possibilités d'application dans le domaine des biomatériaux. La capacité intrinsèque des acides biliaires à s'autoassembler permet de produire des matériaux souples dont les applications sont variées, notamment dans le domaine de la libération des médica-ments. Par ailleurs, la possibilité d'intégrer des acides biliaires dans le squelette de polymères a aussi été explorée dans le cadre de la fabrication d'élastomères. Le présent article de synthèse porte sur une sélection de matériaux pouvant être préparés à partir d'acides biliaires et sur les avantages que comportent ces molécules. Une attention particulière est accordée à la mise au point de matériaux souples et de matériaux rigides. On y décrit les matériaux souples comme étant maintenus par des interactions intermoléculaires faibles, tandis que les matériaux rigides, dans lesquels les acides biliaires sont incorporés dans le réseau polymérique par des liaisons covalentes, sont mécaniquement plus solides.
