Natural Polymers from Biomass Resources as Feedstocks for Thermoplastic Materials
Macromolecular Materials and Engineering - Tập 304 Số 5 - 2019
Kerstin Müller, Cordt Zollfrank, Markus Schmid
AbstractWith the objective of a more sustainable circular economy, one long‐term goal is the utilization of renewable resources as feedstock for the production of polymer‐based materials. In order to successfully process such materials using existing industrial‐scale technologies or even recycling processes, the natural polymers must have thermoplastic properties. ...... hiện toàn bộ
Polypyrrole‐Fe3O4 Magnetic Nanocomposite Prepared by Ultrasonic Irradiation
Macromolecular Materials and Engineering - Tập 291 Số 1 - Trang 68-74 - 2006
Guihua Qiu, Qi Wang, Min Nie
AbstractSummary: Ultrasonic irradiation was employed to prepare polypyrrole (PPY)/Fe3O4 magnetic nanocomposite by chemical oxidative polymerization of pyrrole in the presence of Fe3O4 nanoparticles. This approach can solve the problem in the dispersion and sta...... hiện toàn bộ
Structure and Morphology of New Bio‐Based Thermoplastic Polyurethanes Obtained From Dimeric Fatty Acids
Macromolecular Materials and Engineering - Tập 297 Số 8 - Trang 777-784 - 2012
C. Bueno-Ferrer, Elodie Hablot, Florence Perrin‐Sarazin, Marı́a Carmen Garrigós, Alfonso Jiménez, Luc Avérous
AbstractBio‐based TPUs from dimer acid‐based polyols are synthesised by using a two‐step prepolymer process including reactive processing. The effect of the polyol on the final chemical structures, morphologies and properties of bio‐based TPUs is evaluated by different analytical techniques. It is observed that the percentage of hard segment (HS) distributed in org...... hiện toàn bộ
Polyurethanes Based on Castor Oil: Kinetics, Chemical, Mechanical and Thermal Properties
Macromolecular Materials and Engineering - Tập 293 Số 11 - Trang 922-929 - 2008
Elodie Hablot, Dan Zheng, Michel Bouquey, Luc Avérous
AbstractPolyurethanes based on vegetable oil were synthesized with castor oil and toluene diisocyanate, isophorone diisocyanate or hexamethylene diisocyanate, using dibutyltin dilaurate as a catalyst. The effects of the nature of the diisocyanate on the evolution of the kinetics, as well as the physical and mechanical properties and the thermal stability, of the di...... hiện toàn bộ
Kinetic and Thermodynamic Studies of Emulsion Polymerization of a Sugar Monomer by Calorimetry with Compensation Heating and Differential Cooling
Macromolecular Materials and Engineering - Tập 288 Số 6 - Trang 516-524 - 2003
Adrian Cosmin Dobre, Emile‐Joseph Yaacoub, Adrian Schumpe
AbstractThe kinetic and thermodynamic features of free‐radical batch emulsion polymerization of a sugar monomer (3‐MDG) and butyl acrylate (BA) were investigated in a power compensation calorimeter. The homopolymerizations as well as the copolymerization have been studied. The overall activation energy of 3‐MDG homopolymerization was 140 ± 3.8 kJ · mol−1<...... hiện toàn bộ
Flame Retardancy of Polymers: The Role of Specific Reactions in the Condensed Phase
Macromolecular Materials and Engineering - Tập 301 Số 1 - Trang 9-35 - 2016
Bernhard Schartel, Birgit Perret, B. Dittrich, M. Ciesielski, Johannes Krämer, Patrick Müller, Volker Altstädt, Lin Zang, Manfred Döring
Characterization of Low‐Molecular‐Weight PLA using HPLC
Macromolecular Materials and Engineering - Tập 295 Số 1 - Trang 58-66 - 2010
Fabio Codari, Davide Moscatelli, Giuseppe Storti, Massimo Morbidelli
AbstractHPLC is applied and assessed as an effective tool to investigate both the production of PLA by polycondensation and its corresponding degradation. A new HPLC calibration procedure, through which it is possible to fully characterize LMW PLA samples by determining the concentration of each individual oligomer, is developed. A comparison between HPLC, ... hiện toàn bộ
Development of a Self‐Assembled Peptide/Methylcellulose‐Based Bioink for 3D Bioprinting
Macromolecular Materials and Engineering - Tập 304 Số 11 - 2019
Carla Cofiño, Soledad Pérez‐Amodio, Carlos E. Semino, Elisabeth Engel, Miguel A. Mateos‐Timoneda
AbstractThe introduction of 3D bioprinting to fabricate living constructs with tailored architecture has provided a new paradigm for biofabrication, with the potential to overcome several drawbacks of conventional scaffold‐based tissue regeneration strategies. Hydrogel‐based materials are suitable candidates regarding cell biocompatibility but often display poor me...... hiện toàn bộ
Morphology and Thermomechanical Properties of Melt‐Mixed Polyoxymethylene/Polyhedral Oligomeric Silsesquioxane Nanocomposites
Macromolecular Materials and Engineering - Tập 295 Số 9 - Trang 846-858 - 2010
Miguel Sánchez‐Soto, S. Illescas, Henry W. Milliman, David A. Schiraldi, Asier Aróstegui
AbstractThe influence of the functionalization of fully condensed POSS cages on the properties of POM‐based nanocomposites is studied. POSS with different organic substituents [glycidylethyl, aminopropylisobutyl, and poly(ethylene glycol)] are taken into account and melt mixed with POM. Good dispersion was achieved upon the addition of amino functionalized POSS, le...... hiện toàn bộ
Morphology, Thermal Stability, and Mechanical Behavior of [Poly(propylene)‐grafted Maleic Anhydride]‐Layered Expanded Graphite Oxide Composites
Macromolecular Materials and Engineering - Tập 292 Số 2 - Trang 155-168 - 2007
Frances T. Cerezo, C. Preston, Robert A. Shanks
AbstractPP‐g‐MA‐layered EGO composites were prepared directly by solution blending. Two types of PP‐g‐MA/EGO composites were prepared using different mixing methods: distributive and dispersive. In this study, the effects of the mixing method of EGO on the crystalline structure and thermo‐mechanical properties o...... hiện toàn bộ
