Повний текст джерелаThermo-responsive linear graft copolymers and hydrogels with different topologies have been designed and their nanostructure, their rheological properties as well as their tunable mechanical properties have been investigated. In the case of hydrogels, the self-assembly of the thermo-responsive sequences, which serve as secondary interactions, induces in isochoric conditions a strong enhancement of both stiffness and elongation at break, including also remarkable fatigue properties. Specifically, this reinforcement is totally reversible by switching on/off the associations. It is clearly shown that the topology of the network displays a crucial influence on the mechanical performance of hydrogels, especially the resistance to fracture. After a careful investigation of the structure by 2-D neutron scattering and tensile experiments, different nanostructures are proposed according to the topology. Finally, this concept of thermo-toughening of hydrogels through a controlled microphase separation has been extended to other polymeric networks combining LCST and UCST type polymers

Повний текст джерелаTo specifically study the impact of phase-separation processes on hydrogels mechanical reinforcement, we worked under isochoric conditions developing architectures not only thermo-responsive but also able to keep a high level of hydration on both sides of the phase-separation temperature. For this purpose, grafted hydrogels have been formulated from a chemically cross-linked hydrophilic polymer network grafted with thermo-sensitive side-chains of LCST type (PNIPAm). From this primary structure and keeping constant the weight ratio between the hydrophilic and thermo-responsive parts, we demonstrate that the thermodynamic characteristics of the phase transition (enthalpy and temperature transitions) are only very weakly dependent on the molar mass of PNIPAm grafts as well as their self-assembly process which leads to cylindrical domains concentrated in PNIPAm grafts. Like the nanocomposite materials, the formation of these dense polymer domains stabilized by physical interactions highly enhances both the gels stiffness and fracture resistance at high temperature by dissipating energy. We show that this temperature-controlled reinforcement increases with the molar mass of the PNIPAm grafts. Varying the hydrophilic/thermo-responsive parts weight ratio while keeping constant the molar mass of the grafts, opposite behaviours at low and high temperatures were established. When the hydrophilic cross-linked network weight is high compared to the one of thermo-responsive grafts, the hydrogels exhibit good properties at low temperature (entropic elasticity) whereas at high temperature, their mechanical behaviour is controlled by the phase-separated domains concentrated in PNIPAm grafts (energetic elasticity). The phase-separation phenomenon of PNIPAm grafts being thermo-reversible by nature and the interactions between these chains being weakly dynamic at high temperature, we demonstrate that these grafted hydrogels exhibit both adhesive and shape-memory properties. Finally, expanding the phase-separation concept, we show that replacing the hydrophilic network by a UCST type thermo-responsive one allows getting a dual thermo-response with phase-separation occurring at both low and high temperatures. While these transition temperatures are perfectly correlated to the thermodynamic characteristics of each polymer, the mechanical reinforcement is more dependent on the energy due to the nature of interactions developing inside the UCST network (H-bonds) or between the LCST grafts (H-bonds and hydrophobic interactions) during the phase-separation process

Повний текст джерелаDiese Arbeit befasst sich mit der RAFT-vermittelten Synthese und Charakterisierung von stimuli-empfindlichen Polymeren und ihrer Selbstorganisation zu „intelligenten” Hydrogelen. Die Hydrogele wurden so entwickelt, dass sie bei niedrigen Temperaturen stark quellen, bei Temperaturerhöhung jedoch reversibel in einem hydrophoben, kollabierten Zustand umgewandelt werden. Mit dem permanent hydrophoben Polystyrol (PS) und dem hydrophilen, thermisch schaltbaren Poly(methoxy-diethylen¬glycol-acrylat) (PMDEGA) als Bausteine, wurden unterschiedliche Gelierungsverhalten und thermische Übergangstemperaturen erreicht. Zur Synthese von Diblock-, symmetrischen Triblock- und dreiarmigen Sternblock-Copolymeren wurden neue funktionelle Kettenüberträger entwickelt. Diese gestatteten es, tert-butyl Benzoeester und Benzoesäure Endgruppen in die Polymere einzubauen, die einerseits eine effiziente Analyse mittels Routine 1H-NMR und darüber hinaus eine spätere Funktionalisierung der Endgruppen mit einer Fluoreszenzsonde ermöglichten. Da über PMDEGA kaum Daten vorlagen, wurde der Einfluss von Molekulargewicht, Endgruppen und Architektur auf das thermo-responsive Verhalten untersucht. Die speziellen Kettenüberträger ermöglichten es, gezielt hydrophobe wie hydrophile Endgruppen in die Polymere einzuführen. Die Trübungspunkte der wässerigen Lösungen von PMDEGA zeigten sich bis zu relativ hohen molaren Massen abhängig gegenüber allen untersuchten Variablen, nämlich dem Molekulargewicht, der Art und Zahl von Endgruppen. Durch Variation der diversen Parameter ließ sich die Schalttemperatur von PMDEGA in physiologisch relevanten Temperaturbereich von 20 bis 40 °C einstellen. Um die Polymere für einen zweiten Stimulus, nämlich Licht, empfindlich zu machen, wurden Azobenzol-funktionalisierte Acrylate synthetisiert und statistisch mit MDEGA copolymerisiert. Die Zusammensetzung der Polymeren wurde variiert und das isotherme Schalten der Löslichkeit durch Licht untersucht. Obwohl ein reversibles Schalten erreicht wurde, waren die Unterschiede zwischen den Trübungstemperaturen von UV-Licht bestrahlten und unbestrahlten Proben nur gering. Interessanterweise senkte die UV-Bestrahlung, d.h. ein erhöhter Gehalt von cis-Azobenzol-Gruppen, die Trübungstemperaturen herab. Dies ist genau umgekehrt als für azobenzolbasierten Systeme klassisch beschrieben. Die Gelbildung der verschiedenen Blockcopolymere von PS und PMDEGA wurde mittels Rheologie untersucht. Dabei traten deutliche Unterschiede auf, zwischen dem Gelierungsverhalten der Diblockcopolymere, die nur einen PS Block enthalten, dem der symmetrischen Triblockcopolymere, die zwei assoziative PS Endblöcken besitzen, und dem der Sternpolymere, die drei assoziative PS Blöcke aufweisen. Unabhängig von der Länge des hydrophilen Blockes, bilden Diblockcopolymere des Typs PS11-PMDEGAn keine Gele, sondern selbst bei hohen Konzentrationen von 40 Gew. % Lösungen. Im Gegensatz dazu bildeten die Triblockcopolymere des Typs PS8-PMDEGAn-PS8 Gele bei niedrigen Temperaturen, vereinzelt schon ab 3.5 wt. %. Mit steigender Temperatur, tritt bereits unterhalb des Trübungspunktes für diese Systeme ein Gel-Sol Übergang auf. Der Gel-Sol Übergang bewegt sich zu höheren Temperaturen mit steigende Länge des hydrophilen inneren Blocks. Dieser Trend verstärkt sich mit zunehmender Anzahl von Endblöcken und deren Länge. An der Trübungstemperatur veränderten sich die mechanischen Eigenschaften aller Gele signifikant und die gebildeten flüssigen Dispersionen ließen sich reversibel beim Abkühlen wieder zu Gel schalten. Diese Arbeit, zeigt dass PMDEGA ein bei niedrigen Temperaturen gut wasserlösliches, nicht-ionisches, thermisch-schaltbares und wahrscheinlich biokompatibles Polymer ist. PMDEGA liest sich einfach mittels den RAFT-Verfahren molekular maßschneiden, mit spezifischen Endgruppen und komplexen Polymerarchitekturen. Solche amphiphilen Triblock- und Sternblock-Copolymeren hoher Molmasse, wirken als assoziative Telechele. Daher eigenen sich bei entsprechendem Design diese amphiphilen Blockcopolymere als effiziente Verdicker und Gelbildner mit einstellbaren mechanischen und thermischen Eigenschaften.

A new kind of thermo-responsive biological hydrogel scaffolds was synethized in this studies. First, P(NiPAAm-MAA) hydrogels were polymerized with N-isopropyl acryamide (NiPAAm) and Methylacrylic acid (MAA). Then the P(NiPAAm-MAA)-PEG-HA hydrogels were synthesized with Hyaluronic acid (HA) by cross-linking the Polyethyl glycol bisamine (PEG-diamine). The new hydrogles combined both advantages of NiPAAm and HA which including better mechanical properties, biodegradable and biocompatibility. The characteristic of P(NiPAAm-MAA)-PEG-HA hydrogels were evaluated by H-NMR, FT-IR and Viscometer. The swelling ratio and water content of hydrogels were measured in different pH value at 37℃. And the lower critical solution temperature (LCST) of the hydrogels was measured with different temperature by Viscometer. The hydrogels were immersed in PBS (pH=7.4) at 37℃ to observed the change of weight lost. The surface of hydrogels after freeze-drying were observed by SEM. Finally, MTS activity assay of hydrogels cultured for 24, 48, 72 hours. The results showed that the hydrogels exhibited a LCST at 34℃ and swelling ratio was between 4-8 times and water content was between 73-93%. The swelling ratio and water content depended on the pH value of PBS solution. MTS activity culture prove that the hydrogels were no toxicity. So The new thermo-responsive P(NiPAAm-MAA)-PEG-HA hydrogels will have great potential applications in tissue engineering.

Abstract In this study we examined the behavior of freshly isolated rat hepatocytes cultivated within thermal-sensitive hydrogels based on N-isopropylacrylamide (NIPAAm) and acrylic (AAc). The hydrogel scaffold can mimic the in vivo extracellular matrix and provide a three-dimensional environment for cell proliferation and differentiation. Hepatocyes were encapsulated in NIPAAm-AAc copolymer hydrogel beads and cultured in the rotation cell culture system (RCCS) that could provide a microgravity cell culture environment. Factors such as rotation speed of RCCS, hydrogel encapsulation, cell numbers in hydrogel beads, culture condition (static or dynamic), and medium oxygen level were studied for its influence on cell aggregate size, albumin secretion rate, and urea production rate. Hydrogel copolymer modified with galactosamine, which provides a galactose moiety for recognition by hepatocytes surface receptors, was found to drastically up-regulate the metabolic functions of hepatocytes.

In this study, we reported the preparation of thermo-responsive supramolecular hydrogels via inclusion complexation between cyclodextrins (CDs) and peptide amphiphiles (PAs). Alkylamine were used as the macroinitiator of ring-opening polymerization (ROP) to synthesize PAs. CDs threaded onto alkyl chain and form inclusion complex. The network structure of hydrogels was composed of hydrophobic interactions between alkyl chain and inner cavity of CDs, hydrogen bonding between CDs and side chain of PAs. The gel-sol transition temperature and gelation concentration were tuned by alkyl chain length, type of amino acids and CDs, the molar ratio of CDs and PAs. The secondary structure of peptides was mainly random coil. C12Thr20+α-CD hydrogels formed lamellar packing and the one bilayer thickness decreased with increasing temperature. The intelligent hydrogels could be promising in tissue engineering.
