“…To address the interface challenge, silane coupling agent is usually used to alter the surface property of silica and improve the filler–polymer interaction. The silanol group in silane would react with silica surface and then exposed tail groups outward to silica surface (i.e., SH, CH 3 , and NH 2 ) . The presence of these functional silane molecules would greatly influence the polymer–filler interface properties.…”

The effect of interface property on the mechanical behavior of silica-polybutadiene composites is systematically investigated via combined experimental and dynamics simulation. In experiment, the interface property is controlled by SiO 2 particle size, silane coupling agents, and silane grafting density. The effects of these control parameters on the vulcanization kinetics, tensile strength, and dynamic mechanic properties are investigated and discussed. Both the experimental and simulation studies reveal the pivot role of filler-polymer interface on the mechanical reinforcement. Simulation study reveals that the constrained polymer layer (12 nm) surrounding the silica particles shows increased stress from 30 to 230 MPa, which is identified as the major reason for the overall enhancement of 100% modulus from 0.8 to 1.6 MPa. The molecular mechanics of interface from simulation is well correlated to the experimental results in this study, which provides a molecular level understanding of the relationship between interfacial interaction and mechanical reinforcement.

“…Explanation is given by the occurrence of interaction between alkoxy groups of TESPT and silanol groups on silica surface during the mixing process, leading to the reduced hydrophilicity of silica surface and, thus, improved rubber–filler interaction. The enhanced rubber–filler interaction also contributes to a greater dis‐agglomeration of silica leading to the improved degree of silica dispersion in the rubber matrix .…”

“…Several organosilanes have been developed and evaluated over the years . The most widely used silane coupling agent for tire applications is bis ‐(triethoxysilylpropyl) tetrasulfide (TESPT) which has been reported to provide not only a good coupling efficiency, but also additional crosslinks in the rubber vulcanizates .…”

The influence of silane coupling agent on properties of silica-filled compounds under peroxide curing was investigated. bis (triethoxysilylpropyl) tetrasulfide (TESPT) was selected in this study and its content was varied from 0 to 12% w/w of silica. It is found that with increasing TESPT content, bound rubber content, tensile strength, elongation at break and tear strength are enhanced. By contrast, magnitude of Payne's effect, modulus at 100% elongation (M 100 ) and heat build-up are decreased. The changes of such properties are attributed to the reduction of crosslink density in conjunction with the improvements of both rubber-filler interaction and degree of filler dispersion with increasing TESPT content in the peroxide curing system.

This article covers recent developments of material research in Thailand with a focus on environmental sustainability. Data on Thailand’s consumption and economic growth are briefly discussed to present a relevant snapshot of its economy. A selection of research work is classified into three topics, namely, (a) resource utilization, (b) material engineering and manufacturing, and (c) life cycle efficiency. Material technologies have been developed and implemented to reduce the consumption of materials, energy, and other valuable resources, thus reducing the burden we place on our ecological system. At the same time, product life cycle study allows us to understand the extent of the environmental impact we impart to our planet.
