Multiscale Modeling of Polymer Based Nanomaterials

Smith G.D., Smith J.S., Bedrov D., Borodin O., Smith G.D., Smith J.S., University of Utah, US

In materials design and engineering there is a need for fundamental information that spans large scales of time and distances, from the quantum chemical nature of interactions to the macroscopic mechanical, and electrical properties. In [...]

Morphological Implications of the Interphase; Linking Crystalline and Amorphous Regions in Semi-Crystalline Polymers

Rastogi S., Terry A.E., Eindhoven University of Technology, NL

In semi-crystalline polymers, a range of morphologies can be obtained in which a chain may traverse the amorphous region between the crystals or fold back into the crystals leading to adjacent or non-adjacent re-entry, depending [...]

Effect of Nano-architectural Control on Optical Loss in Electro-optic Polymers

Huang D., Parker T.C., Lumera Corporation, US

Polymer electro-optic (EO) devices show great promise for high-speed telecom data transmission, broadband radio frequency (RF) signal distribution, and high-speed data transfer within the next generation of microprocessors running at 20 GHz and above (i.e., [...]

Direct Observation of the Length of Molecular Cooperativity in Melts of Ultrathin Glass Formers

Overney R.M., Sills S., University of Washington, US

It is our great pleasure to submit this paper, which provides the long awaited microscopic real-space information about the glass transition process in polymers. In the light of the comments made by Nobel Laureate P.W. [...]

Modeling of PDMS – Silica Nanocomposites

Smith G.D., Smith J.S., Smith G.D., Smith J.S., Borodin O., University of Utah, US

A hydrogen bonding pathway between polydimethylsiloxane (PDMS) and hydroxyl groups on a silica surface was studied using quantum chemistry calculations of disiloxane and hexamethyldisiloxane molecules with small silica clusters. A newly developed classical force field [...]
