“…The XRD pattern in Figure 1B showed sharp peaks at 2θ = 23.12°, 25.21°, 26.68°, and 28.87°, corresponding to the (400), (002), (−202), and (−302) planes of low‐temperature Wo phase (α‐CaSiO 3 ), which was corresponding to the triclinic crystal structure with space group P ¯1 (PDF 27–1064). [ 44 ] Besides, trace amount of calcite, quartz, mullite, and feldspar impurity minerals were observed.…”

In order to increase the applicability of wollastonite (Wo) in polycarbonate (PC) polymer, surface modification of Wo was carried out using different modifiers containing silane coupling agent KH570, stearic acid (SA), and sodium dodecylbenzene sulfonate. The physical, physic-chemical, and application properties of modified Wo were evaluated. Results showed that KH570 modified Wo had narrower particle size distribution, higher absolute zeta potential and were more evenly distributed. Scanning electron microscope study confirmed their changes in morphology and aspect ratio during the modification process. The tensile strength of Wo/PC composites, in which KH570-modified Wo was used were superior to those in which original Wo or other modifiers modified samples were used. The maximum tensile strength of 65 ± 1 MPa was obtained by adding 15 wt% KH570-modified Wo. Thermal analysis indicated that adding Wo to the polycarbonate increased the residue content but decreased the thermal decomposition temperature and glass transition temperature slightly, regardless of unmodified or modified Wo. These results indicated that the well-modified Wo mineral had the potential to replace expensive carbon and glass fibers as fillers in polycarbonate products.
