“…Control over dispersion was brought forward by a series of experimental studies that are now able to construct phase diagrams and probe material structure with unprecedented detail. Experiments continue to explore and propose structure–property relationships necessary to design improved materials. ,− Theoretical modeling continues to offer the most versatile and efficient route toward providing predictions and establishing reasoning for experimental findings. However, given the underlying approximations, computer simulations need to continue to test and challenge the accuracy of theory.…”

Polymer/Nanoparticle Interactions: Bridging the Gap

Materials created by dispersing nanoparticles in a polymer matrix strive to meet the promise of enhanced and often unique properties at a reduced cost. The availability of structure− property relationships and predictive modeling are deemed necessary to tailor materials according to our needs. However, the road from detailed information at the atomistic level to macroscopic properties has been severely segmented due to diverse experimental, theoretical, and modeling methods employed to study polymer−particle mixtures, each with their own advantages and limitations. In this Perspective, we focus on seemingly simple polymer−nanoparticle mixtures where nanoparticles are bare or grafted with chains of the same chemical constitution as the matrix. We present a number of studies that attempt to quantitatively identify where complete miscibility is achieved. As we discuss, features pertaining to the nanoscale dimensions of particles continue to challenge our fundamental understanding on polymer−particle interactions. However, through a concerted approach of theory, experiments, and simulations, recent studies significantly expand our knowledge on the morphological behavior of these systems. Most importantly, our discussion demonstrates how new developments bridge knowledge of microscopic interactions with thermodynamic behavior, an achievement that has far more reaching implications in the area of polymer−particle mixtures.

“…The applicability of the RG approximation needs to be carefully examined. Combination of this two-dimensional USAXS technique and an X-ray imaging technique (Kishimoto et al, 2013) enables us to elucidate the three-dimensional structural distribution of nanoparticles in rubbery materials, which is a key for improving the design of vehicle tyres. One-dimensional scattering intensity profile of silica particles in styrenebutadiene rubber.…”

“…Rubber containing nanoparticles is such a system; the hierarchical structure of the nanoparticles in rubber has a close relationship with reinforced mechanical and viscoelastic properties of filled rubber (reinforcement effect) (Wang, 1998). For clarifying the mechanism of the reinforcement effect, the structure of nanoparticles needs to be studied over a wide structural scale; hence both small-angle X-ray scattering (SAXS) (Ehrburger-Dolle et al, 2001;Kishimoto et al, 2008;Koga et al, 2008;Chevigny et al, 2011;Baeza et al, 2012;Takenaka, 2013) and X-ray imaging techniques (Kishimoto et al, 2013) have been used. Apart from the reinforcement effect of nanocomposites, SAXS techniques are widely used to reveal the hierarchical structures of nanoparticle aggregates (Hyeon-Lee et al, 1998;Kammler et al, 2004;Rai et al, 2012).…”

“…The material properties of the separate phases are required as input data for FEA simulations, in this case the mechanical properties were determined experimentally by physical nano-indentation material characterisation tests. Kishimoto et al used IBSim to study inhomogeneous local deformation of rubber matrices, where uniformly and non-uniformly distributed silica particles were embedded [ 35 ]. By using IBSim models, more accurate results were obtained showing that the inhomogeneous local stress fields strengthened the mechanical properties, such as the ultimate strength, of the material.…”

Image-Based Simulation (IBSim) is the process by which a digital representation of a real geometry is generated from image data for the purpose of performing a simulation with greater accuracy than with idealised Computer Aided Design (CAD) based simulations. Whilst IBSim originates in the biomedical field, the wider adoption of imaging for non-destructive testing and evaluation (NDT/NDE) within the High-Value Manufacturing (HVM) sector has allowed wider use of IBSim in recent years. IBSim is invaluable in scenarios where there exists a non-negligible variation between the ‘as designed’ and ‘as manufactured’ state of parts. It has also been used for characterisation of geometries too complex to accurately draw with CAD. IBSim simulations are unique to the geometry being imaged, therefore it is possible to perform part-specific virtual testing within batches of manufactured parts. This novel review presents the applications of IBSim within HVM, whereby HVM is the value provided by a manufactured part (or conversely the potential cost should the part fail) rather than the actual cost of manufacturing the part itself. Examples include fibre and aggregate composite materials, additive manufacturing, foams, and interface bonding such as welding. This review is divided into the following sections: Material Characterisation; Characterisation of Manufacturing Techniques; Impact of Deviations from Idealised Design Geometry on Product Design and Performance; Customisation and Personalisation of Products; IBSim in Biomimicry. Finally, conclusions are drawn, and observations made on future trends based on the current state of the literature.
