高亲水性有色隐形眼镜的紫外合成与表征
DOI: 10.3969/j.issn.1671-7627.2006.02.004, PP. 15-18
Keywords: 隐形眼镜,彩色,紫外,含水率,抗张强度
Abstract:
以当前研究较多的甲基丙烯酸β-羟乙酯(hema)、n-乙烯基-α-吡咯烷酮(nvp)为单体(质量比1:1),安息香乙醚(bee)为引发剂(1%,质量分数),透明蓝为色料,利用紫外光引发自由基反应,合成了有色隐形眼镜.红外光谱定性说明单体参与了聚合反应,色料质量分数为2.46×10-5时,镜片浸出液ph与人体泪液接近,平均透光率达到97%以上,含水率为66.51%,抗张强度为916.26pa(湿态).扫描电镜下观察到均匀交织的网状结构,进一步证明了镜片的高含水率、高透氧率、高抗张强度.
