    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Poly lactic acid ; Graphene Oxide; Stereocomplex; Nucleation Mechanism; Crystalline Morphology; Filler Structure; Mechanical Properties; Gas Barrier; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : In the past two decades, a burgeoning biorefinery concept has grown in concert with the materials science, contributing to the rise of biobased materials that respect environment and are versatile for various applications. An excellent example is poly(lactic acid) (PLA) that exhibits high strength and desirable degradability. READ MORE

  7. 5. Filler Controlled Morphology in Polymer Blends

    Author : Anders L. Persson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; filled polymer blends; Lewis acid-base properties; co-continuous; rheokinetics; viscosity minimation; polymer solid interactions; crystallinity gradient;

    Abstract : The morphology of a polymer blend can be altered very dramatically when a filler is added. Depending on the mutual interactions of the polymers and their individual interactions with the filler, many different filler distributions are possible. READ MORE
