| 摘 要： | 以过氧化二苯甲酰(BPO)为引发剂，N-乙烯基吡咯烷酮(NVP)和甲基丙烯酸β-羟乙酯(HEMA)在一定温度下共聚得水凝胶，可作为软性角膜接触镜材料．实验发现，随NVP含量的增大，水凝胶的含水量越大，透氧性增大，水凝胶材料的透氧率(Dk／L)的倒数与其厚度成正比．并自行设计了一套角膜接触镜材料透氧性能的测试装置、

| Abstract: | Hydrogel contact lens material was synthesized by copolymerization of NVP and HEMA,and BPO was used as initiator.Oxygen permeability of contact lens is the major motivating factors of wearing contact lens conveniently and safely.The oxygen permeability of the hydrogel materials,with different assembly,water content and thickness were studied.An convenient apparatus was designed for the determination of oxygen permeability of hydrogel membranes. |
