The rice husk ash (RHA) was first modified with epoxidized natural rubber latex (ENRL) and then blended with natural rubber latex (NRL) to prepare NR/RHA composite. The morphological structure, thermal stability and dynamic properties were studied with multiple instruments. FTIR and TGA analysis showed that ENR was grafted onto the surface of RHA. The composite prepared with modified RHA showed better dispersity and reinforcement compared to the composite with unmodified RHA, and the glass-transition temperature tended to be higher.

Adsorption Desorption

Abstract It can be stated that the effect of carbon black in a rubber vulcanizate with regard to dynamic properties can be explained by assuming physical adsorption of rubber on the black surface. The effect can be represented by assuming an adsorbed layer having different properties from the bulk rubber taking the layer thickness to be at least 20 A. Adsorption-desorption from this layer causes non-linearity and may contribute to losses observed in the glass transition. This adsorption is analogous to adsorption of simple liquids in microporous systems such as silica gel and activated carbon.

The dynamic mechanism of liquid–glass transition for Mg 7 Zn 3 alloy is studied by the molecular dynamics simulations. The temperature dependences of dynamic properties during the liquid–glass transition are investigated. Two relaxation processes are clearly observed near the glass transition temperature. The diffusivity deviates from the Arrhenius law after the melting temperature Tm and satisfies the power law before the dynamic singularity temperature Tc owing to the cage effect. The solid- and liquid-like atoms are defined according to the vibration characteristic of atoms. It is found that the solid-like atoms have higher local packing density, lower mobility and potential energy than the liquid-like ones. Based on the evolutions of solid- and liquid-like atoms, the atomic mechanism of dynamic liquid–glass transition is systematically elucidated, which is consistent with the potential energy landscape.
