Hydroxyapatite-poly (vinyl) alcohol nanocomposite powder was synthesized using varying poly (vinyl) alcohol concentrations. The dried powder was compacted into micro-porous disks at a load of 4 tons. The disks were sintered at 1200 degrees C to evolve porous nanocomposites. Size and shape of the pores observed in the scanning electron micrographs were quantified by using image processing software. Ultrasound velocity measurements were done to evaluate mechanical properties non-destructively.
采用不同浓度的聚乙烯醇合成了羟基磷灰石-聚乙烯醇纳米复合材料粉末。将干燥的粉末在 4 吨的压力下压制成微孔圆盘。将圆盘在 1200°C 下烧结以形成多孔纳米复合材料。通过使用图像处理软件对扫描电子显微镜照片中观察到的孔的大小和形状进行定量分析。通过超声速度测量来无损评估力学性能。
