  1. A fully coupled thermo-viscoelastic finite element model for self-folding shape memory polymer sheets

    The thermo-mechanical response of thermally activated shape memory polymers (SMPs) is investigated using finite element analysis (FEA) with a thermo-viscoelastic material model. The SMP can be heated by external sources or internal viscous heating. The modeling results indicate how the coupled thermo-mechanical loading conditions affect the folding and unfolding of SMP sheets in response to localized heating. These results can be used to set guidelines for the design of functional, self-folding SMP structures.

  2. Room temperature deformable shape memory composite with fine-tuned crystallization induced via nanoclay particles

    PLA/TPU/MMT Nanoclay blends demonstrate superior shape memory effect with room temperature deformable capability. By adding 1 wt % MMT nanoclay content into the polymer blend, crystallinity of the composite can be fine-tuned and shows 95% recovery ratio when stretched 100% under room temperature condition.

  3. Evolution of concentration fluctuation during phase separation of polystyrene/poly(vinyl methyl ether) blend in the presence of nanosilica

    The composition evolution of PVME during phase separation, especially for A200-filled blends, is retarded by nanosilica which is attributed to the preferential adsorption of polymer chains on the surface of A200 and the decrease of thermodynamic driving force. However, the weak interaction between R974 and the components of the blend matrix and little effect of R974 on the molecular dynamics of PS chains may result in the weak retardation of concentration fluctuation for blend matrix.

  4. An empirical model to predict temperature-dependent thermal conductivity of amorphous polymers

    Sampath Kommandur and Shannon K. Yee

    An empirical model that can predict temperature-dependent thermal conductivity of amorphous polymers is developed using classical expressions and results of previous studies. The model depends only on fundamental material properties like density, molecular weight of monomer, and speed of sound. The model predicts temperature-dependent thermal conductivity of polymers, transition between vibrational modes, and an upper limit for the thermal conductivity, which are all in good agreement with theoretical and experimental data.

  5. Can Extensional Flow Rupture Macromolecules in an Electrospinning Process?

    Chenggui Sun, Cagri Ayranci, Yu Chen and Yaman Boluk

    Version of Record online: 11 MAY 2017 | DOI: 10.1002/polb.24352

    The fracture of high molecular weight poly(ethylene oxide) (PEO) chains under extensional stretching during the electrospinning of aqueous solutions was investigated by measuring solution viscosities and monitoring the change of molecular weight. The degree of macromolecular chain fractures in 1.0% polymer solutions increased with the increase in molecular weight. The strain rates for stretching and fracturing of macromolecules are critical for the degradation of polymers along with experimental elongational strain rates.
