Pore formation and evolution mechanism during biaxial stretching of β-iPP used for lithium-ion batteries separator

Ding, Lei; Xu, Ruizhang; Pu, Lian; Yang, Feng; Wu, Tong; Xiang, Ming

The morphological evolution and pore formation mechanism of different kinds of ?-iPP spherulites during biaxial stretching were analyzed. The smaller radial-growth spherulite deforms heterogeneous, causing a faster reduction in ?-crystal content and higher orientation degree during longitudinal stretching, while the bigger spherulite derived from the hedrites deformed more homogeneous due…

Facilitate charge transfer at donor/acceptor interface in bulk heterojunction organic photovoltaics by two-dimensional nanoflakes

Yang, Weitao; Ye, Zhixiang; Liang, Tao; Ye, Jian; Chen, Hongzheng

Recently, two-dimensional (2D) materials have been applied in organic photovoltaics (OPVs) as electrode modifier or third component in bulk due to their high charge carrier mobility, various electronic band structure, and facile fabrication via liquid phase exfoliation. Herein, solution exfoliated few layers black phosphorus (BP) and tungsten diselenide (WSe2) were…

A solvent-free porous liquid comprising hollow nanorod–polymer surfactant conjugates

Kumar, Raj; Dhasaiyan, Prabhu; Naveenkumar, Parinamipura M.; Sharma, Kamendra P.

Liquids having permanent porosity can offer significant processing advantages over their solid counterparts. This has recently led to tremendous activity towards the design and development of intrinsic pores in the liquid phase, predominantly for studies involving gas sequestration. We show here the development of a solvent-free mesoporous liquid material based…

Solidification and melting phase change behavior of eutectic gallium-indium-tin

Koh, Amanda; Hwang, Wonseok; Y. Zavalij, Peter; Chun, Seth; Slipher, Geoffrey; Mrozek, Randy

The room-temperature liquid metal alloy of gallium, indium, and tin (galinstan) has been studied as a deformable conductive element for stretchable electronics and soft robotics. While these applications are predicated on the soft and conformable behavior of galinstan, little work has been done to understand the solidification of the liquid…

Multilayered assembly of poly(vinylidene fluoride) and poly(methyl methacrylate) for achieving multi-shape memory effects

Ji, Xiaoying; Chen, Dayong; Zheng, Yu; Shen, Jiabin; Guo, Shaoyun; Harkin-Jones, Eileen

The alternately-organized poly(vinylidene fluoride) (PVDF)/poly(methyl methacrylate) (PMMA) multilayer materials were prepared through layer-multiplying coextrusion. With the multiplication of layers, the thickness of each layer was reduced in proportion and the layer interfaces were enriched generating a broader and more continuous thermal transition temperature (Ttrans) from PVDF to PMMA layers…

Melt-Spun Nanocomposite Fibers Reinforced with Aligned Tunicate Nanocrystals

Redondo, Alexandre; Chatterjee, Sourav; Brodard, Pierre; Korley, LaShanda T. J.; Weder, Christoph; Gunkel, Ilja; Steiner, Ullrich

The fabrication of nanocomposite films and fibers based on cellulose nanocrystals (P-tCNCs) and a thermoplastic polyurethane (PU) elastomer is reported. High-aspect-ratio P-tCNCs were isolated from tunicates using phosphoric acid hydrolysis, which is a process that affords nanocrystals displaying high thermal stability. Nanocomposites were produced by solvent casting (films) or melt-mixing…
