  1. Competitive Effects of Stereocomplexation and Hyper-Conjugation of Triethoxysilyl-Terminated Poly(d-lactide) in Poly(l-lactide) matrices

    Triethoxysilyl-terminated PDLA (eSi-PDLA) was blended with PLLA to undergo terminal hyper-conjugation through hydrolytic polycondensation of the silyl functionalities and stereo complexation with the matrix. The morphology was found to be different from the one formed from the similar blend of PLLA and trimethoxysilyl-terminated PDLA (mSi-PDLA).

  2. Adhesion Tuning at Superhydrophobic States: From Petal Effect to Lotus Effect

    Polyimide with weak hydrophobicity was modified into superhydrophobic surfaces via electrospinning. At superhydrophobic state, high-low adhesions was adjusted by further morphology control and Petal Effect was converted to Lotus Effect. Such non-chemically involved wetting conversion was achieved for the first time.

  3. Shape-Memory Polyurethane Nanocomposites with Single Layer or Bilayer Oleic Acid-Coated Fe3O4 Nanoparticles

    Two series of PU/Fe3O4 nanocomposite films based on commercial shape-memory PU and single layer or bilayer OA-coated Fe3O4 NPs are prepared by solution mixing followed by solvent casting. It appears that the nanocomposite films based on bilayer OA-coated Fe3O4 NPs show slightly superior shape-memory properties over these based on single layer OA-coated Fe3O4 NPs.

  4. Nanoscale Bumps and Dents on Nanofibers Enabling Sonication-Responsive Wetting and Improved Moisture Collection

    Mallinath S. Birajdar and Jonghwi Lee

    Article first published online: 18 JUN 2015 | DOI: 10.1002/mame.201500155

    The formation of clinging nanoparticles half-embedded onto the surfaces of nanofibers and the introduction of nano-craters onto the surfaces were developed for the first time. These unique surface nanoengineering techniques offer the possibility to tailor the properties of nanofibers one degree further from conventional electrospun fibers.

  5. One-Pot, One-Step Strategy for the Preparation of Clickable Melamine Based Microporous Organic Polymer Network

    In this work, the clickable MOP with high surface area is synthesized in one-pot and one-step polymerization process using melamine and independently prepared propargyl anthracene selecting as nitrogen source and carbonyl monomer, respectively. As a model reaction, the feasibility of the click coupling on the acetylene containing MOP is demonstrated using independently prepared fluorescent azido-pyrene.
