  • Hyperbranched Polymer vesicles from self assembly characterization mechanisms and properties to applications
    Chemical Society Reviews, 2015
    Co-Authors: Wenfeng Jiang, Yongfeng Zhou, Deyue Yan
    Abstract:

    Vesicles, including lipid vesicles, surfactant vesicles, as well as Polymer vesicles, have been extensively investigated over the past fifty years. Among them, Polymer vesicles have attracted more and more attention because of their low permeability, superior stability and toughness, in addition to the numerous possibilities for tailoring physical, chemical and biological properties. Polymer vesicles are generally fabricated through the self-assembly of amphiphilic Polymers with a linear architecture. Recently, as representative Polymers with a highly branched three-dimensional architecture, Hyperbranched Polymers have also exhibited great potential for preparing vesicles. The resultant Hyperbranched Polymer vesicles, defined as branched-Polymersomes (BPs), have shown unique properties, such as giant and easily tuned vesicle sizes, facile functionalization, a special formation mechanism, and appealing solution behaviours. In this tutorial review, ten years of advances in BPs have been summarized since their first discovery in the year 2004, including the syntheses of vesicle-forming Hyperbranched Polymers, self-assembly methods, self-assembly mechanisms, as well as the special properties. In addition, the cytomimetic, biomedical and other initiatory applications of BPs are also included.

  • a supramolecular janus Hyperbranched Polymer and its photoresponsive self assembly of vesicles with narrow size distribution
    Journal of the American Chemical Society, 2013
    Co-Authors: Yong Liu, Yongfeng Zhou, Xinyuan Zhu, Haibao Jin, Binbin Jiang, Deyue Yan
    Abstract:

    Herein, we report a novel Janus particle and supramolecular block coPolymer consisting of two chemically distinct Hyperbranched Polymers, which is coined as Janus Hyperbranched Polymer. It is constructed by the noncovalent coupling between a hydrophobic Hyperbranched poly(3-ethyl-3-oxetanemethanol) with an apex of an azobenzene (AZO) group and a hydrophilic Hyperbranched polyglycerol with an apex of a β-cyclodextrin (CD) group through the specific AZO/CD host–guest interactions. Such an amphiphilic supramolecular Polymer resembles a tree together with its root very well in the architecture and can further self-assemble into unilamellar bilayer vesicles with narrow size distribution, which disassembles reversibly under the irradiation of UV light due to the trans-to-cis isomerization of the AZO groups. In addition, the obtained vesicles could further aggregate into colloidal crystal-like close-packed arrays under freeze-drying conditions. The dynamics and mechanism for the self-assembly of vesicles as well...

  • The effect of Hyperbranched Polymer lubricant as a compatibilizer on the structure and properties of lignin/polypropylene composites
    Wood Material Science and Engineering, 2013
    Co-Authors: Shaorong Lu, Shanrong Li, Rihua Ling, Jinhong Yu, Bin Huang
    Abstract:

    Abstract In this work, the lignin/polypropylene (PP) composites were prepared by lignin and PP using Hyperbranched Polymer lubricant (HBPL) as a compatibilizer, which was synthesized by oleic acid and amino-terminated hyperbranch (HBP-NH2) Polymer in toluene solvent. The impact and flexural strength of the resulting composites were investigated. Experimental results indicated that the impact strength and flexural strength of lignin/PP composites modified with HBPL are 52.3% and 63.6% higher than that of untreated systems, respectively. HBPL treatment could also significantly improve the melt flow rate (MFR) of the lignin/PP composites. Meanwhile, the storage modulus (E′) of adding the HBPL was slightly higher than that of the uncompatibilized system. In addition, scanning electron microscope images showed that the dispersion of the lignin added with HBPL in the Polymer matrix was improved. It can be inferred that the lignin and PP matrix interfacial bonding was strengthened.
