“…For instance, previous studies have shown that dimensional stability and impact strength of plastic composite materials [1][2][3][4][5], mechanical properties of rubber materials [11,12], rheological properties of sealants [13] and gloss characteristics of paper [14,15] can be controlled by changing shape/size of PCCs. Anhydrous calcium carbonate has three crystalline polymorphs: calcite, aragonite and vaterite.…”

Calcium carbonate (CaCO 3 ) occurs in two major polymorphs: rhombohedral calcite and orthorhombic aragonite, the latter is thermodynamically metastable. In this study, we first prepared aragonite needle-like particles by introducing CO 2 -containing gas into Ca(OH) 2 aqueous slurry. Then, the resulted aragonite particles were heat treated at 500 • C for 1 h, in order to induce the aragonite-calcite phase transition. Particle structures before and after the heat treatment were characterized mainly by powder X-ray diffractometry (XRD), field emission-scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM). We found that single-crystalline calcite needle-like particles with zigzag surface structures can be fabricated using the phase transition.

“…The shear modulus of fillerreinforced rubber is strain dependent. [36] In the certain range, the shear modulus decreases rapidly as the strain increases. That is due to the collapsing of filler-filler network structure in rubber composites, commonly known as Payne effect.…”

In our work, effects of 2-mercapto-1-methylimidazole modified graphite nanoplatelet (MMI-GN) and carbon black (CB) on static and dynamic mechanical properties of styrene butadiene rubber (SBR) composites were studied. MMI-GN is synthesized by ball-mill process, and the result reveals that π-π interactions existed between MMI and GN. The results demonstrate that the static and dynamic mechanical performances of SBR/CB/MMI-GN composites are significantly improved over these of SBR/CB and SBR/CB/GN composites. Compared with SBR/CB, the tensile strength, tear strength, and modulus at 300% elongation of SBR/CB/MMI-GN-3 are greatly improved by 45%, 27%, and 4%, respectively. And the rolling resistance of SBR/CB/MMI-GN-3 is reduced by 3.7% with remaining almost unchanged in the wet grip property. The superiority of MMI-GN in the enhancement for the overall performance of SBR/CB composites is attributed to the well dispersion of GN throughout the SBR matrix and the enhanced interfacial interactions between GN and the SBR matrix. This work might expedite synthesis of the graphite-based materials for enhancing rubber composites, and enlarge the potential applications of modified graphite to fabricate the high-performance rubber composites.

“…In each case, the storage modulus was comparatively high and nearly constant at strains below 1%. The modulus decreased at higher strains because the filler agglomerates were broken; this effect is known as the Payne effect [16]. Thus, by varying the type and quantity of filler, one can vary the modulus behavior and Payne effect of the filled rubber.…”

This research finds a natural rubber-based material with good dielectric properties and low cost for a foodstuff conveyor belt (FCB) that can be heated with microwaves. For this purpose, epoxidized natural rubber-50 (ENR50) and standard Thai rubber 5L (STR5L) were mixed with a filler mixture of silica and magnesium carbonate. The FCB compound with filler (FCBcF) yielding the best vulcanization time, and the best mechanical, dielectric and dynamic properties, was selected for further study. The optimal FCBcF, ENR50:SiO 2 :MgCO 3 (100:40:40) with microwave pre-heating at 2.45 GHz and 340 W for one minute before vulcanization, was well cross-linked and strongly converted the microwaves to heat. FCBcF also showed satisfactory mechanical properties with reduced cost of raw materials and reduced the curing time by 50% per round. The results demonstrate that pre-heating of FCBcF prior to vulcanization reduces the time and cost of fabricating FCBs, providing long-term economic and environmental benefits.
