Alumina materials have widely been used in industrial fields, such as catalysis and adsorption. However, due to the fast sol–gel process and complicated crystalline-phase transformation, the synthesis of alumina materials with both highly ordered mesostructures and crystallized frameworks remains a great challenge. Herein, we report a novel vesicle-aggregation-assembly strategy to…

Sticky ends in a self-assembling ABA triblock copolymer: the role of ureas in stimuli-responsive hydrogels

T. Shafranek, Ryan; D. Leger, Joel; Zhang, Song; Khalil, Munira; Gu, Xiaodan; Nelson, Alshakim

Directing polymer self-assembly through noncovalent interactions is a powerful way to control the structure and function of nanoengineered materials. Dynamic hydrogen bonds are particularly useful for materials with structures that change over time or in response to specific stimuli. In the present work, we use the supramolecular association of urea…

Unique Isodimorphism of Poly(decamethylene succinate-ran-decamethylene fumarate): Large Pseudoeutectic Region and Fantastic Crystallization/Melting Behavior

Ye, Hai-Mu; Wang, Jing; Wang, Cai-Shui; Li, Hong-Fang

Poly(decamethylene succinate-ran-decamethylene fumarate)s (PDSFs) were synthesized, and their structure and crystallization behavior were systematically studied. All polyesters possess high crystallizability irrespective of composition and display the widest pseudoeutectic region that has been reported to date. Nevertheless, both melting point– and crystallization temperature–composition…

High Performance Thermoplastic Elastomers with Biomass Lignin as Plastic Phase

Huang, Jinhao; Liu, Weifeng; Qiu, Xueqing

For the first time, the coordination-based energy sacrificial bonds have been constructed in the interface between lignin and polyolefin elastomer for preparing a new class of high performance thermoplastic elastomers (TPEs) with biomass lignin as the hard plastic phase. The coordination bonds not only promoted the dispersion of lignin, but…

Liquid crystalline side-chain triblock copolymers consisting of a nematic central subblock edged by photochromic azobenzene-containing fragments: their synthesis, structure and photooptical behaviour

Boiko, N. I.; Bugakov, M. A.; Chernikova, E. V.; Piryazev, A. A.; Odarchenko, Ya I.; Ivanov, D. A.; Shibaev, V. P.

For the first time, symmetrical photosensitive fully liquid crystalline side chain triblock copolymers (pAzo-b-pPhM-b-pAzo) and random copolymers (pAzo-ran-pPhM) with nematogenic phenyl benzoate (PhM) and photosensitive smectogenic azobenzene containing groups (Azo) were synthesized by the combination of RAFT polymerization and subsequent chemical modification. The central block of synthesized…

Ribeiro, Livia M. O.; Falleiros, Larissa N. S. S.; de Resende, Miriam M.; Ribeiro, Eloízio J.; Almeida, Renata M. R. G.; da Silva, Antonio O. S.

The search for appropriate supports for enzyme immobilization has attracted increasing interest in the field of biocatalysis. Immobilized enzymes are catalysts of enormous industrial interest because they combine the advantages of heterogeneous catalysis with the high selectivity and mild operational conditions of enzymes. This study evaluated the use of different…

Anisotropic nanoparticles as templates for the crystalline structure of an injection-molded isotactic polypropylene/TiO2 nanocomposite

Zhang, Peng; Kraus, Tobias

We study the molecular origins of anisotropy in a semicrystalline polymer nanocomposite that is caused by aligned, elongated filler nanoparticles. Our study is based on spatially resolved 2D WAXS/SAXS data that indicates the arrangement of molecules, lamellae, and filler particles in the composite. Isotactic polypropylene (IPP) samples filled with anisotropic…
