In this study, we demonstrate enhanced mechanical properties of three-dimensional graphene/hydroxyapatite (3DG/HA) nanocomposites by employing the Taguchi method. The hydrothermal process time, the total pressure, the hydrothermal temperature, and the weight percent of graphene to the hydroxyapatite were considered as control parameters. The results showed that all parameters were effective in controlling the process. According to the findings, the hydrothermal temperature had the greatest effect on the results. The predicted strength fracture toughness is 2.08 ± 0.30 Mpa.m^0.5, which is within the 90% confidence interval. Microscopic analysis confirmed the presence of graphene sheets with folding and wrinkling in the powders and indicated that various preferential directions played a role in the growth of hydroxyapatite crystals.

在这项研究中，我们证明了采用Taguchi方法增强了三维石墨烯/羟基磷灰石（3DG / HA）纳米复合材料的机械性能。将水热处理时间，总压力，水热处理温度以及石墨烯相对于羟基磷灰石的重量百分比作为控制参数。结果表明，所有参数均有效地控制了工艺。根据发现，水热温度对结果的影响最大。预测的强度断裂韧性为2.08±0.30 Mpa.m ^0.5，这在90％的置信区间内。显微镜分析证实粉末中存在折叠和起皱的石墨烯片，并表明各种优先方向在羟基磷灰石晶体的生长中起作用。
