Impact of Filler Surface Modification on Large Scale Mechanics of Styrene Butadiene/Silica Rubber Composites
Macromolecules, 2011Co-Authors: Klaus Werner Stöckelhuber, A S Svistkov, A Pelevin, Gert HeinrichAbstract:In material science of elastomers the influence of nanoscale and Nanostructured Filler particles is of utmost significance for the performance of innovative rubber products, i.e., passenger car tires with ultralow rolling resistance but high wet-grip performance. A better understanding of the physical characteristics of the Filler–rubber interface and the Filler–rubber interphase as well is necessary to improve the overall macroscopic properties of these elastomeric nanocomposites. Therefore, the surface energies and polarities of Filler particles with different modified surfaces were measured by a modified Wilhelmy technique. In all cases the rubber matrix consisted of a solution - styrene butadiene copolymers, filled with 20 or 40 phr pyrogenic or precipitated silica grades with different surface modifications by silanes, and a carbon black sample as reference. A moving die rheometer was employed to observe the Filler flocculation at elevated temperatures (160 °C) in rubber mixtures containing no curati...

Growth of Carbon Nanotubes on Clay: Unique Nanostructured Filler for High‐Performance Polymer Nanocomposites
Advanced Materials, 2006Co-Authors: Wei-de Zhang, In Yee Phang, Tianxi LiuAbstract:High-performance composites are produced using Nanostructured clay-carbon nanotube (CNT) hybrids as a reinforcing Filler. The intercalation of iron particles between the clay platelets serves as the catalyst for the growth of CNTs, while the platelets are exfoliated by the CNTs, forming the unique 3D Nanostructured hybrid Filler: a 2D clay platelet with several attached 1D CNTs (see Figure). The clay-CNTs hybrid can be directly incorporated into nylon-6 by simple melt compounding.

metal polymer composite with Nanostructured Filler particles and amplified physical properties
Applied Physics Letters, 2006Co-Authors: David Bloor, Paul Laughlin, Adam Graham, E.j. Williams, David LusseyAbstract:The limits of conductivity of a novel elastomeric matrix–Nanostructured nickel powder composite are reported. The conductivity falls by a factor of ⩾2×1014 for compression and by a similar amount in extension. Uncompressed and highly compressed composite displays ohmic behavior but between these limits the current-voltage characteristics are highly nonlinear. The matrix intimately coats the Filler so that even above the expected percolation threshold the composite has a very low conductivity. The conductivity of the composite is increased under all mechanical deformations. These and other unusual properties are amplified versions of smaller effects seen in composites containing less highly structured Fillers.
