- Large-Scale X-Ray Microtomography Analysis of Fiber Orientation in Weld Line of Short Glass Fiber Reinforced Thermoplastic and Related Elasticity Behavior
Abderrahmane Ayadi, Hedi Nouri, Sofiane Guessasma and Frederic Roger
Version of Record online: 17 JUN 2016 | DOI: 10.1002/mame.201500463
Large-scale microcomputed tomography is used to investigate the microstructural features of weld lines in short glass fiber reinforced polymer (SFRP) using helical scanning trajectory. 3D fiber arrangement is obtained along 19.8 mm. Full-scale modeling combining finite element model and 3D imaging demonstrates high potential to correlate macroscopic strain localization in SFRP with local fiber heterogeneities.
- Effects of Surface Deactivation of Carbon Black on Thermomechanical Sensitivity of Filler Networks in Rubber Compounds
Lewis B. Tunnicliffe, Alan G. Thomas and James J. C. Busfield
Version of Record online: 17 JUN 2016 | DOI: 10.1002/mame.201600128
This study examines the dynamics of carbon black reinforced rubber. Weak polymer-filler interactions result in systematic shifting of the onset of the Payne effect to larger strains. The temperature dependence of the filler networks is observed to increase dramatically following graphitization of the carbon black to such an extent that a secondary peak in tanδ above the Tg is observed.
- Polydimethylsiloxane Fluidic Device with Polydopamine-Coated Inner Channel for Production of Uniform Droplets
Dae-Ryong Jun, Yu Ri Choi, Rae Hyung Kang and Sung-Wook Choi
Version of Record online: 17 JUN 2016 | DOI: 10.1002/mame.201600176
A polydimethylsiloxane (PDMS)-based fluidic device with two flow channels is fabricated by using a rapid prototyping method. The inner channels are coated with polydopamine (PDA) for hydrophilic modification. Uniform water-in-oil and oil-in-water emulsion droplets were produced by the PDMS and PDA-coated PDMS fluidic devices, respectively.
- Cationic Hydrolytically Degradable Flocculants with Enhanced Water Recovery for Oil Sands Tailings Remediation
Thomas R. Rooney, Sarang P. Gumfekar, João B. P. Soares and Robin A. Hutchinson
Version of Record online: 17 JUN 2016 | DOI: 10.1002/mame.201600230
Dual functional cationic flocculants are synthesized that become more hydrophobic in response to hydrolysis to expel water and improve sediment consolidation. Micellar radical polymerization of a new cationic short-chain polycaprolactone methacrylate macromonomer combines polyester material properties with the productivity of radical polymerization to afford a family of flocculants with highly tunable final properties.
- Controlled and Tunable Biomimetic Apatite Mineralization of Synthetic Hydrogels
Jacqueline L. Harding and Melissa D. Krebs
Version of Record online: 16 JUN 2016 | DOI: 10.1002/mame.201600151
The selective and predictable mineralization of polymeric hydrogels with CO32− and F− substituted apatites to mimic bone and dental mineralized matrix is demonstrated. The fabrication method provides the ability to tune calcium phosphate composite hydrogels for specific applications.
