  1. DC electrorheological response of polyethylene/organically modified layered silicate nanocomposites

    Distinct separation of the two molecular weight modes of the bimodal HDPE resins significantly enhances the electrorheological response of polyethylene (PE)/organically modified silicate layered nanocomposites. Slower structural relaxation modes introduced by higher molecular weight species in the bimodal PE matrices enhance the ER response of the nanocomposites. The weaker ER response observed for unimodal matrices with faster bulk relaxation modes can be due to a screening effect of prematurely released cationic surfactants.

  2. Fabrication and optical characterization of imprinted broad-band photonic films via multiple gradient UV photopolymerization

    A broad-band photonic polymer film can be imprinted using multiple gradient UV photopolymerization in the presence of cholesteric liquid crystals. Forming a UV intensity gradient and controlling the rate of photopolymerization are key factors in broadening the reflection band. [GRAPHIC]

  3. Effect of molecular weight on conformational characteristics of poly(3-hexyl thiophene)

    This research estimates the radius of gyration (Rg) of P3HT chains using an integrated system consisting of a gel permeation chromatograph, a static light scattering unit, and a viscometer compared with the calculated values for unsubstituted poly(thiophene) (PT) and freely rotated chains. The P3HT chains expanded more than the PT chains and shrunk more than the freely rotating chains. The estimated (Rg) of P3HT chains agreed well with the previously reported calculated values using molecular–dynamics.

  4. Effect of polymer chain stiffness on initial stages of crystallization of polyetherimides: Coarse-grained computer simulation

    A coarse-grained model was developed for two polyimides with slightly different chemical structures but significantly different macroscopic properties (one is semicrystalline, another one is amorphous). In this model, the only difference between these two polyimides is the intramolecular stiffness. Dissipative particle dynamics simulations are performed, demonstrating that this model can reasonably reproduce the difference in crystallization behavior of these polyimides.

  5. Effect of annealing temperature on interrelation between the microstructural evolution and plastic deformation in polymers

    Free volume sites of glassy solids provide fertile positions for nucleation of shear transformations that bring about the plastic deformation at the postyield deformation. Thermal treatment is selected as a procedure to alter the microstructural state variable and study the interrelation between the free volume content and plastic deformation units. While the free volume sites shrink upon annealing, the shear activation volume increases in size which is associated with less localized plastic deformation.
