Strain‐hardening modulus of cross‐linked glassy poly(methyl methacrylate)

01-Jul-2010 | Wendlandt, Michael; Tervoort, Theo A.; Suter, Ulrich W., Journal of Polymer Science Part B: Polymer Physics, 2010

The strain hardening modulus, defined as the slope of the increasing stress with strain during large strain uniaxial plastic deformation, was extracted from a recently proposed constitutive model for the finite nonlinear viscoelastic deformation of polymer glasses, and compared to previously ...

Effect of homopolymer solubilization on triblock gel structure and mechanical response

01-Jul-2010 | Seitz, Michelle E.; Rottsolk, Rebecca L.; Shull, Kenneth R., Journal of Polymer Science Part B: Polymer Physics, 2010

The linear modulus, swelling behavior, and high strain response of a set of well-characterized model triblock gels were investigated to understand the effect of homopolymer solubilized within the micelle core on gel structure and mechanical properties. Structural parameters were obtained from ...

Water cavitation of hydrogels

01-Jul-2010 | Zimberlin, Jessica A.; Crosby, Alfred J., Journal of Polymer Science Part B: Polymer Physics, 2010

Using the cavitation rheology (CR) technique developed in our labs, we show that fluids with negligible interfacial tensions with a surrounding material can be used to induce an elastic, cavitation instability in that material. We do this by changing the cavitation media from air, which was ...

Characterization and electrical transport properties of polyaniline and multiwall carbon nanotube composites

25-Jun-2010 | G. Chakraborty, S. Ghatak, A. K. Meikap, T. Woods, R. Babu, W. J. Blau, Journal of Polymer Science Part B: Polymer Physics, 2010

Polyaniline/multiwalled carbon nanotube (PANI/MWNT) composites were prepared by in situ polymerization. Scanning electron microscope, X-ray diffraction, Fourier transform infrared, Uv-Visible spectroscopy, Fluorescence spectrophotometry were done to characterize the PANI/MWNT composites. Thermal ...

Aggregation behavior of poly([gamma]-benzyl-L-glutamate)-b-polyisoprene-b-poly([gamma]-benzyl-L-glutamate) rod-coil-rod triblock copolymer in N,N-dimethylformamide

25-Jun-2010 | Yoichi Ogata, Kazuhiro Iso, Satoshi Kura, Toshiyuki Hayakawa, Yutaka Makita, Journal of Polymer Science Part B: Polymer Physics, 2010

Solution property of poly([gamma]-benzyl-L-glutamate)-b-polyisoprene-b-poly([gamma]-benzyl-L-glutamate) (GIG copolymer) was studied by using dynamic light scattering and static light scattering for N,N-dimethylformamide (DMF) solution and DMF/toluene mixed solutions. GIG copolymer proved to ...

Water purification by membranes: The role of polymer science

25-Jun-2010 | Geoffrey M. Geise, Hae-Seung Lee, Daniel J. Miller, Benny D. Freeman, James E. McGrath, Donald R. Paul, Journal of Polymer Science Part B: Polymer Physics, 2010

Two of the greatest challenges facing the 21st century involve providing sustainable supplies of clean water and energy, two highly interrelated resources, at affordable costs. Membrane technology is expected to continue to dominate the water purification technologies owing to its energy ...

The tensile properties of electrospun nylon 6 single nanofibers

25-Jun-2010 | Mohamed Basel Bazbouz, George K. Stylios, Journal of Polymer Science Part B: Polymer Physics, 2010

In this article, we have aimed to mechanically characterize the nylon 6 single nanofiber and nanofiber mats. We have started by providing a critical review of the developed mechanical characterization testing methods of single nanofiber. It has been found that the tensile test method provides ...

Two-phase crystallization kinetics of syndiotactic polystyrene

25-Jun-2010 | Andrea Sorrentino, Roberto Pantani, Giuseppe Titomanlio, Journal of Polymer Science Part B: Polymer Physics, 2010

In this work, a two phase crystallization model based on the extension of the Kolmogoroff approach was proposed and verified by comparison with experimental isothermal and nonisothermal crystallization data of Syndiotactic Polystyrene (sPS) in a very wide range of cooling rates, up to 600 °C/s. ...

Adsorption of block copolymers in nanoporous alumina

15-Mar-2010 | Sotiria Karagiovanaki, Alexandros Koutsioubas, Nikolaos Spiliopoulos, Dimitris L. Anastassopoulos, Alexandros A. Vra ..., Journal of Polymer Science Part B: Polymer Physics, 2010

We have studied the adsorption of end-attaching block copolymer chains inside the cylindrical pores of nanoporous alumina. Highly asymmetric PS-PEO block copolymers, with a small PEO anchoring block and a long PS dangling block, were allowed to adsorb onto porous alumina substrates with an ...

Processing-structure-mechanical property relationships of semicrystalline polyolefin-based block copolymers

15-Mar-2010 | Fanny Deplace, Zhigang Wang, Nathaniel A. Lynd, Atsushi Hotta, Jeffrey M. Rose, Philip D. Hustad, Jun Tian, Hisashi ..., Journal of Polymer Science Part B: Polymer Physics, 2010

The incremental plastic deformation of the crystals of block copolymers made of semicrystalline polypropylene endblocks and amorphous ethylene-r-propylene midblocks occurring during step cycle tensile tests has dramatic effects on the stress-strain curves. This can be understood from the ...
