    基于熔融接枝烷基链提升聚丁烯发泡行为研究，韩冲 孙并臻 宫瑞英 李朝旭，高分子学报，2020
    聚烯烃材料引入长支化结构，能够提升材料熔体强度和异相成核作用，使聚合物具备更加优异的发泡性能，从而扩宽材料的应用领域. 本文利用甲基丙烯酸十八烷基酯（SMA）熔融改性聚丁烯（PB），发现其链段缠结程度提升，发泡行为改善. 通过红外谱图的化学结构分析以及材料的力学性能分析，发现随着SMA添加量的增加，材料拉伸强度降低，冲击强度呈现先升高后降低的趋势. 差示扫描量热（DSC）的分析结果表明改性PB的结晶度下降. 采用间歇釜式法制备PB发泡珠粒，利用扫描电子显微镜（SEM）研究发泡珠粒泡孔结构，结果表明：SMA改性后，发泡珠粒平均泡孔尺寸、孔径分布、泡孔密度都得到改善，发泡温度窗口加宽且发泡稳定性提升. 当添加SMA达到3份时，珠粒......

    Asymmetric ionic aerogel of biologic nanofibrils for harvesting electricity from moisture W Yang, X Li, X Han, W Zhang, Z Wang, X Ma, M Li, C Li Nano Energy 2020, 71, 104610
    Artificial asymmetric ionic membranes have attracted great interests in harvesting electricity from ubiquitous water activities, while mostly based on delicately-designed nanopores/nanochannels, either to harness saline water in mimic of cytomembranes or to harness moisture with carbon nanomaterials. Herein, fully b......

  • Nacre-based carbon nanomeshes for a soft ionic actuator with large and rapid deformation. Journal of Materials Chemistry C. X. Han; M. Kong; M. Li;* X. Li; W. Yang; C. Li*DOI: 10.1039/c9tc06186j
    Nacre-based carbon nanomeshes for a soft ionic actuator with large and rapid deformation. Journal of Materials Chemistry C. X. Han; M. Kong; M. Li;* X. Li; W. Yang; C. Li*DOI: 10.1039/c9tc06186j
    Marine molluscs have inspired to construct robust composites with hierarchical microstructures, and also to design artificial muscles with rapid and controllable deformation. Abalone nacre has the unique “brick and mortar” structure, whose two-dimensional (2D) “mortar” can serve both as the strong adhesive between a......

    Incorporation of nanoscale colloidal objects into three-dimensional (3D) hydrogel networks can not only reinforce the hydrogels as “colloidal cross-linkers”, but also add many extra functionalities for diverse applications. For the first time, deformable droplets of liquid metal (LM) in combination with sonication w......

    Porous metal foams have been one of the most sought-after materials owing to their combination of bulk metallic characteristics (e.g., thermal/electrical conductivity and ductility) and nanometric size-effect properties (e.g., catalytic reactivity, plasmonic behavior, and high surface area). Traditional sol-gel appr......
