“…Zhu et al studied the tribological properties of aramid fiber and CSW‐reinforced nonmetallic friction materials. Wang et al demonstrated that CSW improved tensile and thermal properties of silicone rubber. Li et al found that thermal stability of fluororubber (FPM)/CSW was better than that of FPM/anhydrous calcium sulfate composites.…”

The melting and crystallization behaviors, morphology, and mechanical properties of polypropylene (PP)/surface-treated calcium sulfate (CaSO 4 ) whisker (T-CSW), b-PP/T-CSW, and b-PP/polypropylene-graft-maleic anhydride (PP-g-MAH)/T-CSW composites had been investigated via differential scanning calorimetry (DSC), wide angle X-ray diffraction (WAXD), polarized light microscopy (PLM), scanning electron microscopy (SEM), and mechanical tests. We found that T-CSW was an a-nucleating agent and increased the crystallization temperatures of PP, but PP-g-MAH and high loadings of T-CSW had weakly negative effects on the crystallization rates of PP. The T-CSW restrained the formation of b-spherulites, and the spherulitic size decreased in the composites. PP-g-MAH improved the compatibility and adhesion between T-CSW and the matrix.

“…The calcium sulfate whisker is a promising reinforcing material with a high aspect ratio [20]. Because of the remarkable advantages of high tensile strength and elastic modulus, calcium sulfate whiskers are often applied in rubber, paper, plastics, and ceramics as fillers to improve the comprehensive properties, including thermal stability, mechanical strength, chemical resistance, and electrical insulation [21][22][23][24]. The physical properties of the materials are highly dependent on the morphology of the whiskers [25].…”

For effective utilization of the residues, calcium sulfate whiskers were prepared from semi-dry desulfurization residues by hydrothermal synthesis reactions. Aiming at collecting the products with a long length and large aspect ratio, the additives, including sodium oleate, sodium dodecyl benzene sulfonate (SDBS), and sodium citrate, were added to control the growth of the crystal. Compared with no additives, whiskers with relatively a longer length and larger aspect ratio could be obtained in the presence of sodium oleate or SDBS. The sodium citrate made the whiskers thicker and shorter. Then, the effects of the additives on crystal growth and the morphology of the hydrothermal products were investigated with the aid of X-ray diffraction (XRD) patterns and molecular dynamics simulations. According to the results of XRD, the diffraction intensity of the crystal face (400) increased under the influence of sodium oleate, promoting crystal growth along the c-axis. The molecular structures of the corresponding faces were built based on the strong peaks shown in the XRD patterns. The atomic distribution on the computed crystal faces was presented. The interaction energies on different faces were calculated to illustrate the different adsorption configurations of the additives. Among the calculated faces, the interaction energies on (400) were both most negative for sodium oleate and SDBS. Therefore, sodium oleate and SDBS preferred to adsorb on (400). As a result, the growth of (400) was thus inhibited and the crystal grew along the c-axis. Compared with sodium oleate and SDBS, the lowest adsorption energy of sodium citrate on the face (310) indicated that sodium citrate has no positive effect on the directional growth of the crystal parallel to c-axis. The molecular simulation results were virtually identical to the crystal faces analysis results.

“…Calcium sulfate whisker (CSW) is one of the representatives of such inorganic fillers that has many advantages such as high strength, low cost, non-toxicity, and environmentally-friendly nature, making it a desirable reinforcing agent in many fields such as papermaking [6] , plastics [7] , rubbers [8] , and adhesives. However, to the best of our knowledge, CSW has rarely been used to reinforce PVC.…”
