Abstract In this work, a ternary composite of epoxy filled with ND and MS was produced for abrasive applications.Surfactants (oleic acid (OA), sodium dodecyl sulfate (SDS) and Triton TX-100 (TX-100)) were used to improve the particle dispersion and, consequently, the composite properties.The elastic modulus Outdoor Swivel Chair w/Cushion (set of 2) increased up to 76% for the sample with 1 wt% ND and 5 wt% ND using TX-100 (1ND5MS-TX100).Regardless of the filler concentration, the particles did not modify the thermal degradation behavior of the epoxy.Thermogravimetric (TGA) and dynamic mechanical (DMA) analyses suggest a strong Nail Care Kit particle-matrix interface, also evidenced in scanning electron microscope (SEM) micrographs.
The composites presented superior tribological performance.1ND5MS-TX100 presented a wear rate of 2.19 x 10-3 mm3.Nm-1, 61.3% lower than the epoxy.
Also, all composites significantly reduced the roughness of the marble, being proportional to the abrasives concentration.Overall, composites with TX-100 presented improved wear behavior.
