Abstract Despite undergoing a substantial reduction with increasing temperature the presence of carbon black added to the strength of both natural and styrenebutadiene rubber at temperatures up to 185° C. The magnitude of reinforcement was primarily dependent upon filler surface area although at the higher temperatures when this dependence is not so marked both high structure and particle activity appear advantageous. No theory of carbon black reinforcement can reasonably ignore the morphological characteristics of the material whose action it is attempting to explain. The concept of within aggregate voids, and occluded rubber envisaged by Medalia and used in this paper to describe the effect of fillers on rubber modulus, provides an interesting molecular meaning to the effects that have hitherto been explained on the basis of “shell” theories. Occluded rubber might reasonably be viewed as a type of shell since it undoubtedly represents a polymer zone in which molecular mobility is restricted. Furthermore the view of rubber being pulled from the interstices of an aggregate, manifestly a stress softening action, provides a source of plastic flow and mechanical hysteresis in the region of the aggregate—an apparent prerequisite for reinforcement.

Atomic Form Factor

Temperature affects both elastic and inelastic scattering of electrons in a crystal. The Debye-Waller factor, B, describes the influence of temperature on the elastic scattering of electrons, whereas the imaginary part of the (complex) atomic form factor, fc = fr + ifi, describes the influence of temperature on the inelastic scattering of electrons (i.e. absorption). In HRTEM simulations, two possible ways to include absorption are: (i) an approximate method in which absorption is described by a phenomenological constant, μ, i.e. fi; - μfr, with the real part of the atomic form factor, fr, obtained from Hartree-Fock calculations, (ii) a more accurate method in which the absorptive components, fi of the atomic form factor are explicitly calculated. In this contribution, the inclusion of both the Debye-Waller factor and absorption on HRTEM images of a (Oll)-oriented GaAs crystal are presented (using the EMS software.Fig. 1 shows the the amplitudes and phases of the dominant 111 beams as a function of the specimen thickness, t, for the cases when μ = 0 (i.e. no absorption, solid line) and μ = 0.1 (with absorption, dashed line).
